    专利说明:

    The invention relates to an apparatus and method for analyzing drilling mud, particularly excavated material, from the end of a drill string transported with the drilling mud.
    It is known from the prior art to analyze in drilling, especially in oil wells, the drilling mud used for drilling and in particular with this transported to the surface fracture material, ie material that has been removed at the bottom of a drill string. In this case, valuable information about the condition of the borehole and the drilling process itself can win, which contributes significantly to the safety and efficiency of a bore. Examples of these are the patents and patent applications published under the numbers US Pat. No. 6,386,026 B1, US Pat. No. 7,642,474 B2, US Pat. No. 2008/0196942 A1, US 2015/0013448 A1 and US Pat. No. 20140333754 A1.
    The object of the invention is to provide an improved technology for the analysis of drilling mud, in particular of removed material, which is conveyed from the drill head end of a drill string to the surface.
    This object is achieved according to the invention by a device and a method having the features of claims 1 and 8, respectively.
    It is known that different types and compositions of minerals have different properties. In the determination of minerals and
    Mineral compositions are predominantly determined in the art for properties related to the reaction of the minerals to visible and non-visible radiation. This can be, for example, X-rays, gamma rays or light in the visible and invisible spectrum.
    The influence of the crystal structure of the individual minerals on the respective electromagnetic waves is observed, recorded and analyzed. In order to make reliable statements about the material properties in this form of rock analysis, it is usually necessary to evaluate individual discrete samples. This poses no problem under laboratory conditions. However, if one wishes to continuously analyze minerals during a continuous process, such as during drilling, this method has many disadvantages. The previous solutions do not offer any solutions for this, but rather put individual discrete measurements one after the other in order to simulate a continuous data flow.
    Furthermore, it is known to associate the strength properties of a rock with the type of rock. For this purpose, the material can be crushed, for example, which determines how much force is required for the crushing. However, this information alone is insufficient for an accurate determination of a mineral composition.
    In the invention, although the material to be analyzed is also comminuted and this process is detected, it is not only the force required for the comminution, but the event of breaking of the individual pieces of material is detected.
    This detection can be carried out according to the invention in two ways, each of which can be used alone but also complementary to each other.
    In the first embodiment, the stress applied to breakage (pressure of the rolls) and the deformation or vibrations generated thereby of at least one roll of a crusher are detected while crushing the material to be analyzed.
    In the second embodiment, acoustic information is detected as the material is shredded. Expressed simply simplified, the "crunching" is thus taken up during the comminution.Of course, the vibrational properties of the roller also influence the crunching and are taken into account accordingly.
    In both variants of the invention, therefore, a mechanical stress / force caused by the breakage and a deformation or a sequence of vibrations caused by the breaking of the material during comminution are detected. These oscillation sequences or characteristics are then assigned to different rock structures.
    Common to both variants is that the analysis of the breakage can take place in a continuous material flow and therefore no discrete samples are required or analyzed. It is also essential for the invention that the pressure, the deformation and / or the vibrations are not considered punctually but always over time, since in this way the individual components can be analyzed for their fracture properties and not only for their hardness, as it is known in the art.
    Accordingly, in a preferred embodiment of the invention, characteristics of the above-mentioned changes with respect to the respective materials are stored on the arithmetic unit and compared during operation with the detected changes.
    Further preferred embodiments of the invention are
    Subject of the remaining claims.
    Further features and advantages of the invention will become apparent from the following description of a preferred
    Embodiment of the invention with reference to the drawing. This shows:
    Fig. 1 highly schematically a system for automated analysis of drilling mud, in particular of removed material, which is conveyed from a drill head side end of a drill string to the surface, wherein the system comprises a device according to the invention.
    In the plant 1 shown in FIG. 1, drilling mud, which is represented by a first arrow 2, is directed onto a vibrating screen 3. For the purposes of the invention, drilling mud is understood to mean both the fluid used for drilling (also referred to as "drilling fluid" or "mud") and the materials carried away with the fluid during drilling (also referred to as "cuttings" or "cavings"). Understood. An analysis of the removed material is therefore also understood in the context of the invention as analyzing the drilling mud.
    The vibrating screen 3 separates the part of the drilling mud that can be reused for drilling from the components to be analyzed. The proportion which can or should be supplied for reuse is represented by a second arrow 4.
    Of course, this portion of the drilling mud before its reuse (recycling) can be fed to a further treatment or / and other analyzes. Thus, for example, for this part of Bohrschlamxns a proportion of organic compounds or a mean density can be determined or he can, for example, go through different filters.
    Still on the vibrating screen 3 located the remaining portion of the drilling mud passes under a sprinkling 5, which washes the material. Thereafter, it is received by a camera 6 in the illustrated embodiment.
    The images of the camera 6 can be used for different purposes. For example, the size and shape of the material can be determined. The resulting benefits and applications are explained below.
    The material (represented by a third arrow 7) then passes into a crusher 8 (also referred to as a "crusher") which in the illustrated embodiment has two rollers 9 between which the material is passed.
    The rollers 9 crush the material, resulting in the breaking of individual chunks noises or the rollers come in specific for breaking vibrations. These vibrations are detected by one or more sensors 10 for detecting the mechanical and / or acoustic vibrations of at least one roller and / or the material, and forwarded to a computing unit 11, which determines a break characteristic from the sensor data, due to which preferably automatically or computer assisted It is detected which material is being crushed by the rollers. When interpreting the breakage characteristic, the images of the camera 6 can also be drawn, since pieces of different sizes can cause different breakage characteristics. A camera 6, in particular for determining the size of individual material components, can therefore advantageously be used in addition. Furthermore, the camera 6 can be used to determine a number of the pieces of material falling in the comminutor, which likewise advantageously supports the analysis of the breaking properties.
    In addition, the arithmetic unit 11 can establish a relationship between the determined material compositions and the time, and thus perform a lithological or petrographic analysis of the bore and conclude on the stability of the bore.
    Of course, also produce materials that were not irrigated and recorded, typical characteristics, which is why a system without the corresponding components 5, 6 for sprinkling and picking can operate according to the invention.
    Furthermore, an analysis can be made only for a part of the drilling mud, for example, to make the system 1 correspondingly small. For this purpose, for example, only a percentage of the drilling mud can be conducted into the plant or only a part of the material remaining on the vibrating screen 3 is analyzed. For this purpose, for example, an additional vibrating screen may be provided which directs only a portion of the material to the crusher.
    According to the invention, the material does not have to be comminuted between two rollers 9, although this is preferred in the invention. The crusher 8 can also be designed with more rollers 9 or roller pairs. It is also possible to use only one roller or two or more rollers in succession and to pass the material between this roller (s) and a fixed resistor, such as a plate, and thereby to comminute it.
    The comminuted material (represented by a fourth arrow 12) passes to the crusher 8 on a conveyor belt 13, where it is first uniformly spread and smoothed by a roller 14. The conveyor belt 13 then passes with the smoothed, comminuted material (represented by a fifth arrow 15) past different sensors 16.
    The sensors 16 can perform additional measurements according to known methods. For example, the sensors 16 may be sensors for X-ray fluorescence analysis, gamma spectroscopy and / or near-infrared spectroscopy.
    After the additional, optional analyzes, the material can be disposed of, as indicated by a sixth arrow 17. Of course, discrete samples of this discarded material can also be taken and drained to be additionally fed to conventional analysis, optionally "offline" in a laboratory.
