    ® PROCESS FOR OPERATING A SEDIMENTARY BASIN COMPRISING HYDROCARBONS, BY MEANS OF A STRATIGRAPHIC MODELING.
    @) Process for exploiting hydrocarbons within petroleum.
    of a sedimentary basin, by means of a stratigraphic simulation coupled with a hydrological model and a diagenetic model.
    For at least one time step, by means of a stratigraphic simulator, a meshed representation of the basin studied is determined comprising at least one mineralogical composition and a porosity within each mesh. Then, by means of a hydrological model, at least one hydrological zone is delimited and at least one chemical composition of the fluids and a direction of circulation of the fluids are determined in each of the cells located in the zone. Then at least the chemical composition of the fluids, the mineralogical composition and the porosity are updated in each of the meshes of the meshed representation by means of a diagenetic model comprising a balance of hydrological flows, established by means of at least the directions of circulation. of fluids and from which an order of mesh path by fluids is determined, and comprising a reaction kinetic model, modeling the interactions between the chemical composition of the fluids and the mineralogical composition in the mesh.
    Application in particular to exploration and exploitation
    The present invention relates to the field of exploration and exploitation of petroleum deposits or geological gas storage sites.
    Oil exploration consists of finding hydrocarbon deposits within a sedimentary basin. Understanding the principles of the genesis of hydrocarbons and their links with the geological history of the subsoil has enabled the development of methods for assessing the petroleum potential of a sedimentary basin. The general approach to evaluating the petroleum potential of a sedimentary basin involves going back and forth between a prediction of the petroleum potential of the sedimentary basin, carried out on the basis of measured information relating to the basin studied (analysis of outcrops, seismic surveys, drilling, for example), and exploration drilling in the various zones with the best potential, in order to confirm or deny the potential predicted beforehand, and to acquire new information making it possible to clarify the predictions of petroleum potential in the basin studied.
    The petroleum exploitation of a deposit consists, from information gathered during the petroleum exploration phase, in selecting the zones of the deposit having the best petroleum potential, in defining exploitation schemes for these zones (for example at using a reservoir simulation, in order to define the number and positions of exploitation wells allowing optimal recovery of hydrocarbons), to drill exploitation wells and, in general, to set up the infrastructures of production necessary for the development of the deposit.
    The oil potential of a sedimentary basin can be assessed either probabilistically or analytically. The analytical approach is most often implemented using computer software, allowing the synthesis of available data and the simulation of the geological history of the basin studied. Depending on the complexity of the geological history of the basin studied, the family of software used for the analytical approach can include one, two or three-dimensional simulation of sedimentary, tectonic, thermal, hydrodynamic, and chemical processes. organic and inorganic which are involved in the formation of an oil basin. This is called an approach called "basin modeling".
    Concerning more particularly the modeling of sedimentary processes, so-called “stratigraphic simulation” software is implemented. This software aims in particular to evaluate different hypotheses on the sedimentary processes that have contributed to the stratigraphic architecture of a basin observed today. Conventionally, the simulation of the history of the filling of a sedimentary basin takes at least into account the following parameters: (1) the space available for sedimentation, created by tectonic and / or eustatic movements, (2) the sediment supply in the basin, either by the borders, or by means of an in situ production or precipitation, (3) the transport of these sediments in the available space created. The DionisosFIow® software developed by IFP Energies nouvelles (France) is an example of software implementing a stratigraphic simulation.
    The inclusion of diagenesis in stratigraphic simulation software is currently limited. In fact, most often, only the impact of mechanical compaction on the thickness of the sedimentary layers, as these layers are buried in the basin, is taken into account. Thus, in the document (Granjeon & Joseph, 1999), we describe compaction laws which link the porosity of the sediment to the burial, thus making it possible to quantify the volume of the sedimentary layers. If such a restriction can be satisfactory (i.e. producing a simulation result close enough to reality) for sedimentary rocks of elastic type, it cannot lead to a satisfactory simulation of the early diagenesis of carbonate rocks.
    In general, diagenesis is called the succession of physicochemical and biological modifications undergone by sediments having deposited within a basin, and which contribute to changes in texture and composition of these sediments, after their deposition. Indeed, the sediments which deposit in a sedimentary basin are movable and rich in water. These sediments will be subjected, during their progressive burial in the basin, to circulations of fluids which will transform them. This succession of modifications is conventionally divided into two main stages: early diagenesis and late diagenesis or burial. Early diagenesis, or eogenesis, most often designates the sequence of transformations, or fluid-rock interactions (superficial) occurring during or just after the deposition of a sediment, before it is covered by another sediment . This direct relationship with the water-sediment interface and the area of influence of surface fluids (meteoric during emersion or marine in the case of hardened underwater bottoms) also implies an important role of biological factors on diagenetic processes . The so-called late diagenesis designates the mineral transformations of the more or less compacted sediments and rocks, long after their deposition, linked to circulations of non-superficial fluids. It includes any other physico-chemical modification, a priori slower (compaction, mineralogical transformation, dissolution).
    It is therefore clear that the circulation of fluid in a basin has a major impact on the transformations undergone by rocks during geological time. This impact is particularly important in the case of carbonate deposits, because their mineralogical composition makes them particularly sensitive to chemical alteration, and causes a great variety of diagenetic reactions (dissolution, precipitation, recrystallization ...). The marine area constantly flooded with water generally oversaturated with respect to carbonate mineral species constitutes a preferential locus for the destruction of porosity by marine cementations. In the particular case of evaporative contexts, the precipitation of evaporites and the dolomitization processes (of sebkha and reflux) will locally occur and affect the initial properties of the sediment. Under subaerial conditions (emersion of previously deposited sediments), the presence of relatively dilute water, which can show a wide range of saturation with respect to carbonate minerals induced different processes: dissolution, cementation, neomorphism (local dissolution and precipitation with modification of the mineralogy).
    Thus, the processes occurring during the diagenesis of a carbonate rock have the effect of modifying the intrinsic characteristics of the rock (nature and geometry of the grains forming the matrix of the rock; nature and geometry of the pores of the rock), and in fact, the petrophysical and mechanical properties of carbonate rock.
    In general, the diagenetic transformations undergone by a rock over time have as a consequence the variation over geological times of the mineralogical composition, of the petrophysical properties (porosity, permeability for example) and mechanical of the rocks (elastic modules). Thus, it clearly appears that a stratigraphic simulation must, to be the most representative of reality, to model the diagenetic effects induced by the circulation of fluid during the geological history of a sedimentary basin.

    We know the document (Whitaker et al., 1999) which describes a simplified simulation of the effects of the presence of fluids on the evolution of the mineralogy and the porosity of carbonate sedimentary deposits. More specifically, the authors describe a hydrological model composed of three zones with distinct hydrological properties: a vadose meteoric zone (emerged zone whose porosity is not entirely saturated by the meteoric fluid), a phreatic meteoric zone (emerged zone whose porosity is fully saturated with meteoric fluid) and a mixing zone (seawater / freshwater). The thickness of each of these zones, known as hydrozones, is calculated at each time step according to the DupuitGhyben-Herzberg method as defined in the document (Vacher, 1988). The authors also describe a diagenetic model, based on predefined mineralogical transformation rates, from the literature, for each mineral and for each hydrozone, and functions of the climate (arid versus humid). This model also uses the principles of thermodynamics and mass conservation to predict the occurrence of these mineralogical transformations (for example, the dissolution of calcite cannot take place in the presence of aragonite). However, the kinetic effects linked to variations in temperature, pressure, etc. are not considered in this diagenetic model. In fact, according to this approach, only the location of the different hydrozones conditions the mineralogical transformation kinetics. Thus, these are constant rates of mineralogical transformation, taken from the literature, and independent of the kinetic effects, which make it possible to simulate the evolutions of the mineralogy and of the porosity in each hydrozone. In addition, the geochemical evolution of groundwater (i.e. the evolution of the chemical composition of groundwater) in each hydrological area is not considered. In addition, in this model, no transport of fluid inside a hydrozone is considered, which is not realistic, especially in the case of the phreatic type hydrozone. Therefore, diagenesis is assumed to be uniform in these areas. And finally, these hydrological and diagenetic models are not coupled to a stratigraphic simulation, that is to say that the result of these simulations is not used as input parameters and / or constraints of the stratigraphic simulation, and vice versa.
    We also know the document (Whitaker and Smart, 2007) which describes an improvement of the previous kinetic laws of mineralogical transformation, via a geochemical modeling OD, however not coupled to a stratigraphic simulation. In particular, this improved approach is based on the PHREEQC model (Parkhurst, 1995) to define laws in each of the hydrozones, function of different parameters such as the thickness of the vadose and phreatic zones, the PCO 2 , the meteoric water flow , porosity, evapotranspiration, oxidation and mixing of water (only at the vadose / phreatic interface). The kinetic laws defined are linear, assigned to each hydrozone, even to parts of hydrozone (the top of the water table for example) and do not take into account the potential kinetic effects. Similarly, no fluid transport is modeled in this approach.
    We also know the document (Whitaker et al., 2014) which describes a stratigraphic modeling taking into account the effects of meteoric diagenesis (early diagenesis taking place during the emergence of carbonate sediments, linked to fresh water called "meteoric" >) undergone by carbonates. More precisely, this approach makes it possible to predict the distribution of petrophysical properties (permeability and porosity) pre-burial by simulating the distribution of the facies of deposits of an isolated carbonate platform (that is to say a platform not fed by flows hydrological from the continent, such as an island) and the meteoric diagenesis undergone by these facies. In this approach, the hydrozones are defined in the same way as in the previous studies, as well as the mineralogical transformation rates which can vary locally within each hydrozone as described in (Whitaker and Smart, 2007). For example, the authors show that in a semi-arid climate, the soils are poorly developed, the thickness of the vadose zone is small and evapotranspiration is limited, which leads to the precipitation of calcite in the vadose zone and in the first meters near the level of the water table. However, this approach does not model the influence of a circulation of fluid, in particular lateral.
    Thus, in general, the approaches described in the documents of the prior art use a simple hydrological model, not including the modeling of an aquifer and more generally, of an upstream-downstream hydrological flow. Thus, this type of approach is only applicable to morphological configurations of the isolated carbonate platform type and cannot be generalized to other types of platforms (attached, barred ...), for which the taking into account of an aquifer and an upstream-downstream hydrological flow including a flow balance calculation is necessary to have a complete monitoring of the evolution of water chemistry and therefore of fluid-rock interactions. This approximation, if it can be acceptable when the simulation of the diagenesis is limited to an oil reservoir (for example an isolated carbonate platform), it cannot be valid at the scale of the sedimentary basin, for which the hydrological flows are significant over time, in particular the upstream-downstream flows of fluids.
    The present invention aims to overcome these drawbacks by means of a stratigraphic simulation coupled with a hydrological model and a diagenetic model defined so as to take into account the hydrological flows within a sedimentary basin, thus making it possible to model more realistically. the evolution of the chemical composition of the fluids circulating within the basin and therefore the fluid-rock interactions over geological time.
    The method according to the invention
    Thus, the present invention relates to a method for exploiting hydrocarbons within a sedimentary basin, said basin resulting from a succession of sedimentary deposits over time, at least part of said sedimentary deposits having been subjected to circulations of fluids , said method being implemented on the basis of measurements of properties relating to the stratigraphy and to the hydrology of said basin and by means of a stratigraphic simulator executed on a computer, said stratigraphic simulator allowing the determination of a meshed representation representative of the stratigraphy of said basin for a succession of time steps.

    Detailed description of the process
    In general, one of the objects of the invention relates to a method for exploiting the hydrocarbons present within a sedimentary basin, comprising at least three coupled simulations: a stratigraphic simulation of the stratigraphic evolution of a sedimentary basin, a hydrological simulation delimiting hydrological zones, and a simulation of the diagenetic effects generated by hydrological flows (for example of vertical and / or lateral direction) intervening within the basin during geological times. According to an implementation of the invention, the stratigraphic, hydrological and diagenetic simulations are carried out according to three sequential stages, or alternatively, the models on which the stratigraphic, hydrological and diagenetic simulations are based are resolved simultaneously.
    Generally, a sedimentary basin is formed by successive sediment deposits over time. These sedimentary deposits are in particular subjected to circulations of fluids during geological times, circulations of fluids which contribute to a modification of the properties of these deposits. The present invention aims to quantify these modifications, and in particular at least the changes in mineralogical composition and porosity, by means of a stratigraphic simulation according to the prior art, coupled with a hydrological model and a diagenetic model. According to an implementation of the invention, other petrophysical properties (such as permeability) and / or mechanical properties (such as Young's modulus and Poisson's ratio) of the sedimentary basin are determined in addition.
    The present invention is particularly suitable in the case of carbonate and evaporitic deposits subjected to hydrological flows, but can however be applied to any type of deposit such as elastic deposits.
    The present invention requires having:
    - measurements relating to the stratigraphy of the basin studied: these are measurements carried out in situ, making it possible in particular to determine the architecture of the basin at present, to qualify the various sedimentary deposits (mineralogical composition, thicknesses, ages, conditions deposits etc) or the geological events undergone by these sedimentary deposits (fracturing, erosion, subsidence, etc). These measurements can consist of outcrop and / or analog studies, of log measurements carried out along wells drilled in the studied basin, of rock samples taken for example by coring, in seismic images obtained following seismic acquisition campaigns. From the measurements thus carried out, one can define the input parameters of a stratigraphic simulation, such as the morphology of the basin, the sediment inputs (inorganic, such as the production of different carbonates, and possibly organic), their transport for each time step. For example, the morphology for a given time step can be obtained from the morphology measured at the current time (on a seismic image for example) and by means of a structural restoration, a technique well known to the specialist, who can for example be carried out using KronosFIow software (IFP Energies nouvelles, France). Likewise, the sediment inputs for a given time step can be determined from the volume of the sedimentary layer observed at present, divided by the duration of the sedimentation. Finally, the transport parameters for a given time step can be estimated from deposit profiles established from the observation of the basin at the current time. These measurements can also make it possible to define input parameters of the hydrological model and of the diagenetic model according to the invention.
    - measurements relating to the hydrology of the basin: these are measurements carried out in situ, making it possible in particular to qualify hydrological parameters of the basin, at present and preferably for previous geological times. Currently, it can be a question of measurements of the pluviometry, the evaporation, the flows of the aquifers of the basin studied. For previous geological times, we can for example extrapolate current measurements from knowledge of previous climates deduced from the observation of the basin to the current one, or we can assume that the transport parameters are equivalent to those of current rivers , and that rainfall and evaporation are defined with reference to the current climatic zones. These measurements make it possible in particular to define the transport parameters necessary for a stratigraphic simulation, but also to define parameters of the hydrological model and of the diagenetic model according to the invention.
    - a stratigraphic simulator: this is software run on a computer aiming to reconstruct the sedimentary processes that have affected the basin from geological time t to present time. A digital stratigraphic simulation is generally implemented discretely over time, that is to say a stratigraphic simulation simulates the stratigraphic state of the basin for a succession of time steps. A time step of a stratigraphic simulator corresponds to a geological duration during which deposits or sedimentary erosion have been recorded. The properties (including porosity and mineralogy) of these deposits can be relatively heterogeneous at the basin level. The simulation of the history of the filling of a sedimentary basin is carried out using input parameters representative of the sedimentary history of the basin studied. According to an implementation of the invention, the input parameters of a stratigraphic simulation are at least (1) the space available for sedimentation, linked to tectonic and / or eustatic movements and to the mechanical compaction of the sediments (or compaction of the sediments under the effect of the weight of the overlying layers) (2) the supply of sediments in the basin, either by the borders, or through production or precipitation in situ , (3) the transport of these sediments (transport capacity estimated from the characteristics of the sediment such as the size of the grains or their density, the flow of water flowing at the surface of the soil and the local slope of the basin ) in the available space created. The system of equations describing these processes can for example be solved by a spatial discretization in finite volume, and an explicit diagram in finite volumes. According to the invention, the result of a stratigraphic simulation for a time step corresponds to a mesh representation for which each mesh is at least filled with the following information: mineralogical composition and porosity of the sediments. In a very classic way, the mesh representation resulting from a stratigraphic simulation is also populated with properties characteristic of the deposition environment (water depth, elevation of the basin, ...) and is populated in facies. A description of such a stratigraphic simulator can be found in the document (Granjeon and Joseph, 1999). An example of such a stratigraphic simulator is the DionisosFIow software (IFP Energies nouvelles, France). Furthermore, the stratigraphic simulator according to the invention does not model the phenomena of diagenesis linked to transport of fluid.
    According to an implementation of the invention, the method according to the invention comprises at least the following steps 1) to 4), the sequence of steps 1) to 3) being applied for at least one time step of the simulation stratigraphic. Alternatively, steps 1) to 3) are performed simultaneously, which means that the models on which these steps are based are solved simultaneously. This alternative allows greater efficiency in terms of computation time and / or avoiding that the solution of one of the models is a function of the solution of a model solved in the previous step.
    1. Stratigraphic simulation
    2. Determination of hydrological zones
    3. Determination of diagenetic effects
    4. Exploitation of hydrocarbons from the formation
    Preferably, steps 1) to 3) are repeated for each time step of the stratigraphic simulation. Advantageously, steps 1) to 3) are at least repeated for each time step of the stratigraphic simulation for which a simulation of the diagenetic effects on the sedimentary deposits linked to hydrological flows is desired.
    1. Stratigraphic simulation
    It is a question during this stage of simulating the sedimentary deposits within the basin studied for the time step considered. This step is carried out using a stratigraphic simulator as described above, using stratigraphic simulation parameters as described above; these parameters being determined at least from measurements relating to the stratigraphy and to the hydrology of the basin studied as described above.
    According to one embodiment of the invention, this step is implemented by means of a stratigraphic simulator such as that described in the document (Granjeon and Joseph, 1999). An example of such a stratigraphic simulator is the DionisosFIow software (IFP Energies nouvelles, France).
    According to the invention, at the end of this step, a mesh representation representative of the stratigraphy of the basin is obtained for the time step considered, each of the meshes of this representation being informed at least in terms of mineralogical composition and initial porosity , possibly modified by the effect of mechanical compaction. According to an implementation of the invention, each of the meshes of the mesh representation is also indicated in the deposition environment and in facies.
    For purely illustrative purposes, Figure 1A presents a vertical section within a mesh representation resulting from a stratigraphic simulation for a given time step. We can observe in this figure that the architecture of the basin studied for the time step considered is in the form of a bowl in which successive sediments have been deposited, part of these sediments having been brought into the basin by a river F, at minus part of the basin being situated below sea level M. The stratigraphic simulation for the time step considered made it possible to simulate the sedimentary deposit D (mesh layer most at the surface of the basin).
    2. Determination of hydrological zones
    During this step, it is a question of defining at least one hydrological zone within the basin studied for the time step considered, by means of a hydrological model and input parameters of the hydrological model.
    Within the meaning of the invention, a hydrological zone is a zone having hydrological properties (at least the chemical composition of the fluids and the direction of the circulation of the fluids) which can be considered as relatively homogeneous in space for the time step considered. .
    Conventionally, the different types of hydrological zones are:
    - Marine areas, with normal salinity (i.e. close to the average salinity of seawater, around 30 to 35 g / l) and with circulation of fluids essentially vertical and limited to the first meters of sediments (under the water-sediment interface). According to an implementation of the invention, the circulation of fluids in such an area can be represented by a vertical flow of decreasing value;
    - Restricted coastal areas (lagoons, lagoons, coastal lakes), in which the fluid salinity can vary drastically from normal marine salinity (salinity slightly lower than marine salinity, and around 10 to 30 g / l), from brackish conditions to hypersaline conditions (salinity much higher than marine salinity, which can exceed 50 to 100 g / l). According to an implementation of the invention, the circulation of fluid within this type of zone can be represented by a vertical percolation and a lateral flow linked to the reflux of brines.
    - Continental areas, subject to a flow of meteoric fluid (that is to say of non-marine origin). Conventionally, the continental areas are themselves broken down into:
    o a vadose meteoric zone, unsaturated with water, and for which the circulation of fluids can be represented according to an implementation of the invention as essentially vertical (percolation of precipitation of fresh water);
    o a meteoric phreatic zone, saturated with fresh water and for which the circulation of fluids can be represented according to an implementation of the invention as essentially lateral;
    o a mixing zone, formed of sea water and fresh water, with limited fluid circulation, and which can be represented by a zero flux value according to an implementation of the invention.
    According to the invention, several hydrological zones of the same type can co-exist in a sedimentary basin at a given time step.
    In general, the input parameters of the hydrological model are determined from at least part of the measurements relating to the stratigraphy and hydrology of the basin as described above, and from at least part of the information present. in the mesh representation at the end of the previous step.
    According to an implementation of the invention, the input parameters of the hydrological model can include the morphology (topography, limits of geological layers, etc.) of the basin, the porosity and the permeability within each mesh of the mesh representation, the climate medium at the time step considered (rain and evapotranspiration). The permeability in a mesh can be determined from the mineralogical composition and the porosity resulting from the stratigraphic simulation for the time step, as well as from a knowledge of the facies present in the mesh (which is conventionally also an output of a stratigraphic simulation) and by means of a homogenization method as described in patent application EP 3104199 (US 6423664). The permeability in a mesh can also be determined by the specialist based on his general knowledge of the basin.
    Preferably, the hydrological zones are determined in three dimensions, on the scale of the sedimentary basin. According to an implementation of the invention, the distribution and the geometry of the various hydrological zones can be determined using the hydrological model of Dupuis-Forcheimer, which is based on an integration along the verticals of the Navier equation- Stocks and in which the speed of transport of the water in the subsoil (and consequently the level of the aquifers) is conditioned by the pressure gradients in the subsoil. More precisely, we can define a hydrological model based on an equation of the type:
    dh s s —-v ”(wfe) = O with:
    fe hydraulic head [L], t
    time [T], K the symmetric tensor of hydraulic conductivity (or permeability) [LT], S s the coefficient of specific storage [L -1 ], a term source of extraction (pumping) [T].
    The term source Q of extraction corresponds to the recharging of water (or pumping) of the aquifer by precipitation reduced by evapotranspiration, as well as the water supplies at the borders of the simulated zone (contribution from the upstream and export zones downstream areas). According to this implementation of the invention, the substratum of the sedimentary basin is assumed to be impermeable. The resolution of this equation makes it possible to determine the hydraulic properties (hydraulic head and flow speed) at any point in the basin. The elevation of the groundwater roof, which separates the phreatic zone from the vadose zone, and the pressure gradients are deduced from the calculated loads. Such an embodiment of the hydrological model makes it possible in particular to determine the level of the water tables in the stationary state, and therefore for example to divide the continental zone of a sedimentary basin into a meteoric vadose zone, a meteoric phreatic zone and a mixing zone seawater / freshwater.
    According to the invention, once the hydrological zones are demarcated, each of the meshes of the meshed representation of the basin is assigned a chemical composition of the fluids present in the mesh and a direction of circulation of the fluids, at the input of the mesh and / or in out of the mesh.
    According to an implementation of the invention, the direction of circulation of the fluids in the mesh considered is defined by the type of hydrological zone to which the mesh considered belongs. According to an implementation of the invention, in the case where the mesh considered is close to a mesh belonging to a hydrological zone of different type, it is also possible to define a direction of circulation of the fluids between these meshes of different hydrological type .
    According to an implementation of the invention for which steps 1) to 3) have been previously applied for at least the previous time step of the simulation, the composition of the fluids at the input of the diagenetic model for the time step considered corresponds to the composition of the fluids determined at the end of the application of steps 1) to 3) for the preceding time step.
    According to an implementation of the invention for which steps 1) to 3) were not previously applied to a previous time step, the initial chemical composition of the fluids within a hydrological zone given for the step of time considered is predefined by a specialist, depending on the hydrological zone considered and measures relating to the hydrology of the basin as described above. The specialist is fully aware of the means for initializing such a chemical composition for each of the hydrological zones identified.
    According to an implementation of the invention, the chemical composition of the fluids present in a mesh is for example described by the saturation of these fluids with carbonate minerals, the alkalinity and the partial pressure of CO 2 aqueous.
    For purely illustrative purposes, Figure 1B presents an example of the implementation of a hydrological model for the same basin and for the same time step as those considered in Figure 1A. Thus the basin studied, for this time step, comprises several hydrological zones: a meteoric vadose zone ZV, a meteoric phreatic zone ZP and a zone of mixing ZM seawater / freshwater. In this Figure 1B are also presented in the form of arrows the main directions of the hydrological flows in each of these zones (vertical direction for the vadose zone ZV, lateral for the phreatic zone ZP, with zero circulation for the mixing zone ZM), as well as the location of three columns of meshes: the columns COL1 and COL2 which cross at the same time the vadose zone ZV and the phreatic zone ZP, the column COL2 being more downstream (compared to the direction of the flow in the phreatic zone ) as column COL1, and column COL3 crossing only the mixing zone ZM.
    3. Determination of diagenetic effects
    During this step, it is a question of determining at least the evolution of the mineralogical composition and of the porosity induced by the circulation of fluids in the basin studied for the time step considered. According to the invention, this modeling is carried out by means of a diagenetic model taking into account the directions of circulation of the fluids in the basin as determined in the previous step, and of a reaction kinetic model modeling the interactions between chemical composition of the fluids and mineralogical composition in each of the meshes of the mesh representation. Thus, according to the invention, the chemical composition of the fluids is also updated in each mesh of the mesh representation, due to the fluids / minerals interactions in the mesh, but also because the fluids circulate from a mesh to a other.
    According to the invention, the diagenetic model includes:
    - a hydrological flow balance, established at least for each of the hydrological zones, and taking into account the directions of circulation of the fluids identified in the previous step, and from which an order of course of the meshes of the meshed representation is followed, followed by fluids circulating in the basin studied;
    - a reaction kinetic model, modeling the interactions between the chemical composition of the fluids and the mineralogical composition of the sediments, along the path followed by the fluids identified by means of the hydrological flow balance.
    Thus, according to the invention, the diagenetic model is adapted according to the type of hydrological zone, each zone having directions of circulation of the own fluids (for example an essentially vertical direction in the vadose zone, subjected essentially to the percolation of precipitation; an essentially lateral direction in a phreatic zone) and having characteristics in terms of chemical composition of similar fluids (fresh water in the vadose zone; sea water in a marine zone). The chemical imbalance between the fluid and the mineralogy in each mesh of a given hydrological zone generates a modification of the porosity and the initial mineralogy in this mesh, function of reaction kinetics based on quantitative phenomenological laws adapted to the scales of time and d space considered for each diagenetic process.
    According to an implementation of the invention, the reaction kinetic model developed in the document is used (Vacher et al., 1990). In particular, this document describes that the kinetics of a diagenetic reaction representing the evolution over time of the proportion of a mineral A (in the totality of the mineralogical assembly) can be considered more or less analogous to a law first order exponential decay, which can be expressed as:
    dC / dt - -kCA
    Ca - Ca q exp (-ki) t l / 2 = -ln (2) / k where dC A / dt represents the dissolution rate of A, C A and C A0 the concentrations of A (cm 3 / m 3 ) at times t (years) and at the start of the process, k and t 1/2 being respectively the reaction constant and the corresponding half-life of A. According to an implementation of the invention, these changes are determined for the three main carbonate minerals, that is to say aragonite, calcite and dolomite.
    By feedback, the chemistry of the fluid entering the mesh considered is modified at the output, according to the kinetics. This modified chemical composition of the fluid is then transported from one mesh to another in the same hydrological zone, according to the order of mesh path determined from the hydrological flow balance. According to an implementation of the invention, this modified chemical composition of the fluid in a given hydrological zone is also transported to a neighboring hydrological zone, for example vertically and / or laterally.
    According to an implementation of the invention, the hydrological flow balance can be carried out as follows:
    For a vadose meteoric zone, only the vertical flows are considered. The incoming vertical flow comes directly from the infiltration of surface water and the outgoing flow results from a direct transfer of this surface water from the vadose zone to the water table.
    - For the meteoric water table, the lateral flows calculated by the hydrological model (see step 2 described above) are integrated along each vertical to define the horizontal water flow, to which we then add the vertical water flow of surface flowing from the vadose zone to the underlying phreatic zone, and from which the vertical flow escaping at the base of the phreatic zone is subtracted to reach the deeper hydrological zones.
    According to an implementation of the invention, on the basis of this hydrological flow balance, a preferential order of mesh travel is determined for the fluids circulating in the basin such that:
    - in a vadose-type zone: an order of mesh travel is determined according to which the fluids flow independently from one column of meshes to another, and in which, for a given column, the fluids flow from a given mesh of this column towards a mesh directly underlying, including the first mesh of the phreatic zone for the column considered;
    - in a phreatic type zone: an order of mesh path is determined according to which the fluids in this zone circulate from a given column of cells to a column of cells located downstream, the downstream direction being determined by the direction of the flow in the phreatic zone. According to an implementation of the invention, the lateral displacement of the fluids between two adjacent columns is carried out from mesh to mesh, or, alternatively, the chemical composition of the fluids determined for the mesh of a column located in the phreatic zone is averaged before transfer to the next column of cells.
    According to an implementation of the invention, the diagenetic model makes it possible to determine the proportion of the three main carbonate minerals in each mesh of the meshed representation as a function of the initial mineralogical composition and of the duration of the time step according to the following reactions:
    - the aragonite initially present is changed to calcite and / or the initial porosity is increased;
    - the calcite initially present is changed to dolomite and / or the initial porosity is increased;
    the dolomite 1 initially present is modified into dolomite 2.
    The reactions thus defined make it possible to represent respectively the dissolution (partial or total) of aragonite and its transformation into calcite, the (partial) dissolution of calcite and its transformation into dolomite, and finally the recrystallization of a dolomite.
    According to an implementation of the invention, from the mineralogical composition and the porosity thus determined at the end of the diagenetic model, and from textural information (for example of lithological facies type, which is an output classical stratigraphic simulation), in addition to this, other petrophysical properties (such as permeability) and / or mechanical properties (such as Young's modulus and Poisson's ratio) are determined at the end of this step. of the sedimentary basin. To do this, it is possible to use a homogenization method as described in patent application EP 3104199 (US 6423664).
    For purely illustrative purposes, FIG. 1C presents an example of implementation of a diagenetic model for the same basin and for the same time step as those considered in FIGS. 1A and 1B. Thus, Figure 1C shows from left to right the evolution of the porosity φ and the percentage of calcite C along respectively the three columns of meshes COL1, COL2 and COL3 presented in Figure 1B. Thus, it can be observed in this FIG. 1C, that the columns COL1 and COL2 are found totally or partially within the meteoric hydrozones. The vertical circulation per descensum within the vadose zone ZV allows 1) to represent the percolation of precipitation within this zone; 2) calculate the vertical recharge of the phreatic zone; 3) to modify the mineralogies and porosity of the meshes of the column specific to the vadose zone. The lateral circulation within the phreatic zone ZP makes it possible to represent 1) the circulation within the phreatic table; 2) to incrementally modify the chemical composition of the fluid; 3) to reflect these changes in fluid composition on the mineralogies and porosity of the meshes of the column specific to the phreatic zone. Column COL3, is found entirely in the marine zone ZM and sees the porosity of the meshes affected by cementing processes only within the first meshes under the water-sediment interface.
    According to a first main embodiment of the invention in which the sedimentary basin comprises at least one hydrological zone of continental type, the diagenetic model can account for the effects induced by circulations of fluids of variable directions according to the hydrological zone considered: percolation vertical for fluids in the vadose zone (due to precipitation) and lateral flow for fluids in the phreatic zone. The diagenetic model can be implemented as follows for this first main embodiment of the invention and as illustrated diagrammatically in FIG. 2:
    - in the vadose zone ZV: the diagenetic modifications, including the modifications of the chemical composition of the fluids, are determined column of cells by column of cells, and independently of a column of cells to another. Within a column (for example COL1 or COL 2 in Figure 2), the passage from one mesh to another, per descensum, is carried by the water flow (shown diagrammatically by the arrow WV in Figure 2) which percolates only vertically in the vadose zone, this vertical flow being induced by precipitation P at the surface of the basin. The diagenetic reactions which take place in the first mesh (at the top of the column) modify: 1) the mineralogical composition M, and the residual porosity φ π within the mesh i; 2) the chemical composition% j of the fluid leaving this mesh i. Thus, the chemical composition of the fluid entering the underlying cell is a function of the chemical composition of the fluid in the overlying meshes. At the bottom of the vadose zone, the chemical composition of the fluid which passes into the phreatic zone is thus the result of the initial chemical composition of the fluid and of the modifications undergone successively in each mesh thus crossed by the vertical flow.
    - In the phreatic zone ZP: the diagenetic modifications, including the modifications of the chemical composition of the fluids, are determined column of cells by column of cells, then the fluids thus modified for a given column are "transported" to the column of cells located downstream, the downstream direction being determined by the main direction of the hydrological flow in the phreatic zone. More precisely, the chemical composition of the fluids, the mineralogical composition M, and the residual porosity φ ΓΙ are determined for each of the meshes of a column COL1 of the phreatic zone, then an average X mO y is carried out on the chemical compositions of the fluids present in the meshes of the water box to the column COL1 considered and then used (transfer schematically by the arrow denoted WP in Figure 2) this average chemical composition X moy input of the wale adjacent downstream COL2. According to an implementation of the invention, the chemical composition of the fluid entering the meshes of a column located in the phreatic zone is the result of: 1) the chemical composition of the fluid originating from the overlying vadose zone; 2) the chemical composition% m arin of the marine water coming from the underlying bevel (shown diagrammatically by the arrow WM in Figure 2); 3) the chemical composition of the fluid X avg in the upstream column, or else a predefined initial chemical composition in the case of the most upstream column of meshes (for example, one can choose a chemical composition of the initial fluid corresponding to the composition from the water table to the present). Thus, in each mesh of the phreatic zone, the chemical imbalance between the chemical composition of the fluid and the initial mineralogical composition (corresponding to the mineralogical composition determined at the end of the stratigraphic simulation step for the time step considered) modifies at least the mineralogical composition M ,, the residual porosity φ ΓΙ within the mesh i and the chemical composition of the fluid. According to an implementation of the invention, these modifications are averaged per column, and a new chemical composition of the fluid is transferred laterally to the adjacent downstream mesh column. Thus, this first main embodiment of the invention aims to represent the effects of a meteoric diagenesis, including the dissolution, recrystallization and cementation processes which take place when a layer of sediment deposited in the marine environment is emerged and subjected to a stream of meteoric fluid.
    According to a second main embodiment of the invention in which the sedimentary basin comprises at least one sedimentary deposit of evaporite type (resulting from a deposit in hyper saline medium), the diagenetic model can account for the effects induced by hydrological flows in variable directions: a vertical percolation (linked to precipitation) and a lateral flow linked to the ebb of brines. The diagenetic model can be implemented as follows for this second main embodiment of the invention:
    - For any mesh whose mineralogical composition is of the evaporitic type, we simulate a process of vertical percolation of the supersalted fluid within the directly underlying meshes. If an underlying mesh is of calcareous mineralogy and if the Mg / Ca ratio of the percolating fluid is greater than or equal to a predefined value (very conventionally fixed at 6), the initial mineralogical composition is modified into a mineralogy of the dolomitic type. The chemical composition of the fluid leaving a mesh is also modified by these fluid-rock interactions. The chemical composition of the fluid entering a mesh is therefore a function of the composition of the fluid in the overlying mesh. This modeling of diagenetic modifications (namely dolomitization) is stopped when the Mg / Ca ratio of the percolating fluid is less than a predefined value, very preferably equal to 6.
    - In parallel, we simulate a lateral flow of brines, to represent the phenomenon of "reflux". According to an implementation of the invention, the chemical composition of the fluid associated with this reflux is the averaged result of the chemical composition of the fluid present in the column of cells in which the diagenetic modification, as described above, has occurred. This reflux is then transferred laterally to the adjacent downstream mesh column.
    4- Exploitation of hydrocarbons from the sedimentary basin
    At the end of the application of the preceding steps 1) to 3), preferably applied for each time step of the stratigraphic simulation, there is available a precise prediction at least of the distribution of the mineralogy and of the porosity, at from which we can for example determine other petrophysical and / or mechanical properties within the basin studied. Such information, which is more reliable, contributes to improving knowledge of the basin studied, and thus makes it possible to determine in particular whether a good quality reservoir is present within the basin, what are the possible migration routes for hydrocarbons, or even for define an operating plan for the identified reservoir.
    Indeed, these properties can be particularly useful at the input of a basin simulation (such as for example carried out by means of the TemisFIow® software (IFP Energies nouvelles, France) which makes it possible in particular to quantify the petroleum potential of a basin, d '' a flow simulation (such as for example carried out using the PumaFlow® software (IFP Energies nouvelles, France)) which makes it possible to define at least one diagram of exploitation of the hydrocarbons present in the basin.
    For example, the determination of an exploitation scheme includes the definition of a number, a geometry and a location (position and spacing) of injector and producer wells, the determination of a type of assisted recovery ( by injection of water, surfactants, etc.), etc. An operating plan for a hydrocarbon reservoir must, for example, allow a high rate of recovery of hydrocarbons trapped in the identified geological reservoir, over a long operating period, requiring a limited number of wells and / or infrastructures .
    Conventionally, the determination of a hydrocarbon exploitation diagram is carried out using a flow simulation, in particular exploiting petrophysical properties such as permeability and porosity. Thus, steps 1) to 3) as described above, preferably repeated for each time step of the stratigraphic simulation, making it possible to improve the knowledge of these properties, the result of the flow simulation is more precise, which improves the step of determining a hydrocarbon exploitation scheme.
    Then, once an exploitation scheme has been defined, the hydrocarbons trapped in the reservoir are exploited according to this exploitation scheme, in particular by drilling the injector and producer wells of the exploitation scheme thus determined, and by installing the infrastructures for production necessary for the development of the deposit.
    Thus, the present invention allows, via a coupling between a stratigraphic simulation, a hydrological model and a diagenetic model, taking into account the effects of hydrological flows within a sedimentary basin. In particular, the present invention makes it possible to model the evolution of the chemical composition of the fluids circulating within the basin and in fact makes it possible to model in a more realistic manner the diagenetic modifications linked to the circulation of fluid in a basin. In this way, the present invention contributes to a better knowledge of the sedimentary basin studied, and thus makes it possible to define conditions allowing an optimal exploitation of this basin.
