MODULAR LOAD CARRIER SEGMENT
BACKGROUND OF THE INVENTION
The present disclosure generally relates to systems and methods for servicing a wellbore, and more particularly to perforator tool assemblies, for example, one or more modular load segments for a perforator tool assembly.
Hydrocarbons, such as gas and petroleum, are generally obtained from underground formations which can be on land or offshore. The development of underground operations and the processes involved in the removal of hydrocarbons from an underground formation are complex. Typically, underground operations involve a number of different steps such as, for example, drilling a wellbore at a desired wellsite, treating the wellbore to optimize production of hydrocarbons , and carrying out the steps necessary to produce and process the hydrocarbons from the underground formation.
Drilling wells are drilled in the ground for a variety of purposes including to tap into formations containing hydrocarbons to extract the hydrocarbons for use as fuel, lubricants, chemical production, and other purposes. When a wellbore is completed, casing can be placed and cemented in the wellbore. Subsequently, a perforator tool assembly may be introduced into the casing, and one or more perforation guns in the perforator tool assembly may be activated, used, actuated, or otherwise caused to detonate an explosive charge to perforate the casing, the formation or both to promote the production of hydrocarbons from the selected formations. Punch tool assemblies may include one or more punch cannons. Punch guns can include one or more explosive charges.
Regardless of the type of explosive charge used to create perforations or fractures, the perforator tool assembly must be designed to deploy the explosive charge (shaped charge) at the bottom of the well and to align or offset the explosive charges according to the needs of a given operation. A well site may require storing various sets of hole puncher to accomplish the desired operation. Thus, there is a need for modular punch tool assemblies which can be designed for a given explosive charge and for a given operation.

DETAILED DESCRIPTION
Certain aspects and examples of this disclosure relate to perforator tool assemblies for use in deployment of one or more explosive charges downhole. The creation of a desired perforation or fracture within the casing of a wellbore or underground formation may require that an explosive charge or a perforation charge be deployed within a drill tool assembly at a specific location within the wellbore and one or more explosive charges are arranged at a precise orientation, offset, distance, or any combination of those these relative to each other within the perforator tool assembly. Providing modular charge segments, including at least modular charge carrier segments and modular charge spacer segments, allows explosive charges to be deployed in a variety of configurations without the need for storage or warehousing of many different components to allow the different configurations required for a given operation. For example, an operation may require that a first set of perforator tool include hollow charges which include explosive material spaced a first predetermined distance and at a first offset from each other. After detonating the shaped charges, the operation may then require that a second set of perforating tool include shaped charges spaced a second predetermined distance and at a second offset from each other. Modular load segments allow these different configurations without the need to store multiple sets of hole punch tools. A supply of modular load segments can reduce costs associated with warehousing and can allow greater flexibility of configurations for shaped loads and for real-time adjustments to a drilling operation. Thus, modular load segments allow easy interchangeability of shaped charges, increased efficiency for assembly punch tool assemblies, and elimination of safety risks due to unintentional activation of the shaped charges.
According to the present disclosure, modular load segments, including at least modular load bearing segments and modular load spacer segments, can allow a unique design for mass production (which can reduce costs), a faculty of multi -phase of hollow charges, adjustment shot by foot of hollow charges, automatic locking of hollow charges, integrated connection for a detonating cord, elimination of secondary components reduction of storage, diversification of manufacturing process, improvement security related to a non-conductive material, reduced assembly time, accommodating customer-specific applications, and real-time ability to change a configuration, and any other security and cost reduction as discussed here in more detail.
The modular load segments of a hole punch assembly can be deployed into the wellbore during any suitable downhole operation. For example, in one embodiment, the modular load segments of a perforator tool assembly can be deployed downhole to facilitate a fracturing operation. In one or more embodiments, the modular load segments of a perforator tool assembly can be deployed downhole for stimulation of a hydrocarbon producing formation, during a plugging and abandonment process to facilitate filling of any openings in the formation, repair of a wellbore, or for any other suitable operation.

In order to facilitate a better understanding of the present disclosure, the following examples of certain embodiments are given. In no event should the following examples be construed as limiting, or defining, the scope of the disclosure.
Various aspects of this disclosure may be implemented in various environments. For example, Figure 1 is a diagram showing an example of a wellbore environment for use of a modular drill tool assembly, according to an aspect of the present disclosure. The system 10 includes a service platform 20 which extends over and around a wellbore 12 which enters an underground formation 14 for the purpose of recovering hydrocarbons from a first production area 40a, a second production area 40b, a third production area 40c, or any combination thereof (collectively, production areas 40). The wellbore 12 can be drilled in the underground formation 14, according to any suitable drilling technique. Although shown as extending vertically from the surface in Figure 1, the wellbore 12 can also be deviated, horizontal, curved, curved over at least some portions of the wellbore 12, or any combination of these. For example, the wellbore 12, or a lateral wellbore drilled off the wellbore 12, can deviate and remain inside one of the production zones 40. The wellbore 12 can be cased, an open hole, to contain a casing and / or can generally comprise a hole in the ground having various shapes or geometries as the specialists in the field know. In the illustrated embodiment, a casing 16 can be placed in the wellbore 12 and fixed, for example, by (at least in part) cement 18.
The service platform 20 can be one of a drilling platform, a completion platform, a reconditioning platform, or another mast structure and can support a production tube 30 in the wellbore 12. The production tube 30 may include segmented pipes which extend below the surface 104 and into the wellbore 12. The present disclosure contemplates any suitable structure for supporting a production tube 30. The service platform 20 may also include a derrick with a working bridge through which the production tube 30 extends downwards from the service platform 20 into the wellbore 12. In certain embodiments, such as in an offshore location, the service platform 20 can be supported by piers extending down to a seabed. Otherwise, in certain embodiments, the service platform 20 can be supported by columns resting on hulls and / or on pontoons which are ballasted under the surface of the water, which can be called a semi-submersible platform. or just a platform. In an offshore location, a casing 16 can extend from the service platform 20 to exclude seawater and contain returns of drilling fluid. It is understood that other mechanical mechanisms, not shown, can control the approach and withdrawal of the production tube 30 in the wellbore 12, for example a traction work coupled to a lifting device, another vehicle service, a coiled tubing unit and / or other appliance.
In one or more embodiments, the production tube 30 may include a transport system 32 and a puncture tool assembly 34 which includes one or more embodiments of the present disclosure. The perforator tool assembly 34 may also be a downhole deployment device or a suitable tool for deployment of the perforator tool assembly 34 at the well bottom. The transport system 32 can be any of a column of hinged pipes, a smooth cable, coiled tubing, and a cable line. For example, a cable line can be coupled to a truck or other logging facility. In one or more embodiments, the production tube 30 may further include one or more downhole tools (not shown in Figure 1), for example above the punch tool assembly 34. The production tube 30 may include one or more packings, one or more completion components such as strainers and / or production valves, sensing and / or measuring equipment, and other equipment which are not shown in Figure 1. In some contexts, the production tube 30 can be referred to as a tool train. The production tube 30 can be lowered into the wellbore 12 to place the perforator tool assembly 34 to perforate the casing 16 and enter one or more production zones 40.
The perforator tool assembly 34 may be coupled via electrical connection to a system controller 108 at surface 104. In one or more embodiments, a system controller 108 may be placed at the bottom of the well or remotely from the system 10. A control signal can be transmitted from the system control unit 108 to the punch tool assembly 34 to cause the punch tool assembly 34 to perform one or more operations. or modify one or more operations of the perforator tool assembly 34.
Figure 2 is a diagram illustrating an example of a modular load carrying segment 200 of a perforator tool assembly 34, according to aspects of this disclosure. In one or more embodiments, the modular load carrying segment 200 is disposed in a perforating tool assembly 34 or any other tool or device suitable for deploying the modular load carrying segment 200 at the bottom of the well. The modular charge-carrying segment 200 fixes a hollow charge, for example an explosive or a piercing charge (see, for example, an element 410 in FIG. 4A), at a predetermined location and orientation. The modular load carrying segment 200 provides interchangeability for a number of shots (explosions of the hollow charge) per foot and a degree of phasing from one hollow charge to another. A reduction in storage of various perforator tool assemblies 34 required to provide phasing and shots per foot commonly used as the modular load bearing segment 200 can be configured in one or more configurations to accommodate various phases and shots per foot . The modular load carrying segment 200 is also suitable for mass production as the modular load carrying segment 200 can be molded or printed in three dimensions which is favorable for mass production. In one or more embodiments, the modular charge carrier segment 200 can eliminate certain potential safety risks such as the modular charge carrier segment 200 can include rubber, plastic or other non-conductive material which reduces the risk of non-detonation intentional or short circuit. In addition, modular load bearing segments 200 comprising such materials can reduce the potential amount of debris which can be unfavorable to downhole conditions as the material can be completely or substantially consumed or sufficiently pulverized. The modular load-carrying segment 200 can also increase loading efficiency and load reduction of shaped charges as the shaped loads are easily inserted into and removed from the modular load-bearing segment 200.
Shaped charges (such as shaped charges 410 illustrated in FIG. 4A) can be placed in a charge opening 250 formed in the modular charge-carrying segment 200. In current assemblies, shaped charges are placed in predetermined notches at a given or specified spacing and a degree of phasing between the hollow charges as determined by the particular assembly which can generally comprise a single mechanical casing of carbon and alloy steel fabrication. The modular load carrying segment 200 includes a load opening 250 which can direct a shaped load to different degrees of phasing and spacing by coupling the modular load carrying segment 200 to one or more other modular load carrying segments 200 as discussed with reference to Figure 4A and Figure 4B. A charge opening 250 can be of any shape, size, dimension or combination thereof to accommodate or allow a shaped charge to be disposed within the modular load bearing segment 200.
The modular load-carrying segment 200 includes an opening 254 and 252 at each end of the modular load-carrying segment 200. The openings 254 and 252 allow the modular load-carrying segment 200 to couple to one or more other modular load-carrying segments 200. For example, an opening 254 can be adjacent to a male connector 270 and an opening 252 can be adjacent to a female connector 272. A male connector 270 of a first modular load-carrying segment 200 can receive the female connector 272 d a second modular load-carrying segment 200. A male connector 270 can be a recessed portion of the modular load-carrying segment 200 sufficient to allow insertion into a female connector 272. An internal surface 222 can form a recessed edge with the female connector 272 so that the female connector 272 receives the male connector 270.
Male connector 270 may include one or more locking tabs 210. Locking tabs 210 may include fasteners, cantilever pressure seals, cantilever arms, cantilever bars - false or any other device or mechanism that flexes or locks to fix modular load segments. A locking tab 210 of a first modular load-carrying segment 200 is configured to pair with a notch 230 for fixing or coupling a second modular load-carrying segment 200 to the first modular load-carrying segment 200. For example, the locking tab 210 can be configured to deflect or flex to allow pairing. The male connector 270 of the first modular load-carrying segment 200 slides or otherwise is positioned inside the female connector 272 of the second modular load-carrying segment 200 so that the locking tab 210 mates with a notch 230 for position the shaped charge in the desired or predetermined orientation. A locking tab 210 may include a fastener, a coupler, a cantilever arm, a latch, or any other mechanism for pairing the locking tab 210 with a notch 230. One or more tabs release 212 can be disposed on the modular load carrying segment 200. A release tab 212 is configured or operates to release the locking tab 210 so that the first modular load carrying segment 200 can be removed or decoupled from the second modular load carrying segment 200. In one or more embodiments, a release tab 212 may not be present as a locking tab 210 may be depressed or otherwise unlocked from a corresponding notch 230. In one or more embodiments, locking tab slots 214 are configured to allow the locking tab 210 and the release tab 212 to be depressed, bent, or deflected to allow a first carrier segment to modular load 200 to be coupled to or released from a second modular load carrying segment 200. Once the release tab 212 is locked or fixed in a notch 230, the rotational or linear movement of the hollow loads is limited or prevented .
In one or more embodiments, at or near or near one or more notches 230, a corresponding indicator 280 can be arranged to indicate an orientation or a phasing of a hollow charge placed inside the carrier segment of modular load 200. While FIG. 2 illustrates the notches 230 5 spaced apart in order to position a hollow load at intervals of fifteen degrees of offset or phasing (for example, 60, 75, 90, 105, 120, etc.) , the present disclosures contemplate that the notches 230 may be spaced by any suitable distance to position the shaped charge of a modular charge-carrying segment 200 at the desired or predetermined offset or phasing. While FIG. 2 illustrates indicators 280 associated with notches 230 10 for offsets or phasing of sixty, ninety, etc. degrees, this disclosure contemplates that indicators 280 may indicate any degree of offset or phasing and may be associated with any one or more notches 230. An indicator 280 may include a label, identifier, or other visual indicator . An indicator 280 may be applied or otherwise affixed to an external surface 220 (as illustrated) or an internal surface 222 of the modular load carrying segment 200. An indicator 280 may be applied via any one or more suitable applicators including but not limited to to screen printing, painting, adhesion, engraving, laser printing, or any other suitable applicator or a combination thereof. In one or more embodiments, the notches 230 may be arranged on the modular load-carrying segment 200 200 in a 360-degree profile so that the notches 230 bypass the modular load-carrying segment 200. In one or more modes embodiment, the notches 230 can be arranged at any interval or location of the modular load-carrying segment 200. For example, notches 230 can be arranged on one side, halfway, or according to any other arrangement on the modular load carrying segment 200.
In one or more embodiments, a modular load carrying segment 200 may include a slot, a space, an opening, or an opening 260 which allows the opening 254 to be enlarged (e.g., the modular load carrying segment 200 can flex, flare or deform outward) so that a shaped charge can be placed in or removed from the modular load bearing segment 200. The width of slot 260 may vary depending on the shape, size, the dimensions or any combination thereof of the shaped charge, the type or bendability of the material of the modular load bearing segment 200, any other factor or any combination thereof . In one or more embodiments, a charge opening 254 may be smaller in size than a shaped charge as a slot 260 is configured to deflect to allow charging and charge reduction of the shaped charge. In one or more embodiments, a charge opening 254 may be of sufficient size so that a slot 260 is not required.
In one or more embodiments, the modular load carrying segment 200 may include a plurality of arms 240 which operate within an arm opening 242. The arms 240 may move along the arm opening 242 in order to grasp a detonator cord (for example a detonator cord 910 discussed in more detail with reference to FIG. 9).
FIG. 3A and FIG. 3B are diagrams illustrating an example of configuration of modular load-carrying segments 200, according to aspects of the present disclosure. FIG. 3A illustrates a modular load-carrying segment 200a in position for pairing with a modular load-carrying segment 200b as indicated by the arrows. FIG. 3B illustrates the modular load-carrying segments 200a and 200b paired such that the locking tab 210 of a modular load-carrying segment 200b is paired with or is in the locked position with a notch 230 of a load-bearing segment modular load 200a. While openings 250 of the modular load carrying segments 200a and 200b are illustrated at a zero degree phase from each other, the present disclosure contemplates that modular load carrying segments 200a and 200b can be paired or configured to be n no matter what degree of phase each other.
FIG. 4A and FIG. 4B are diagrams illustrating an example of configuration of modular charge-carrying segments and of explosive charges, according to aspects of the present disclosure. FIG. 4A illustrates a shaped charge 410 disposed inside a modular charge-carrying segment 200a. A hollow charge 410 is disposed inside a modular charge-carrying segment 200b. A modular load-carrying segment 200b is coupled to a modular load-carrying segment 200a such that the shaped charge 410 of a modular load-bearing segment 200b is at a phasing or sixty degrees offset from the shaped charge 410 d '' a modular load carrying segment 200a. In one or more embodiments, a modular load carrying segment 200b includes a slot 260 and a slot 260 can be used as a guide for aligning the shaped charge 410 of a modular load carrying segment 200b at the desired or predetermined offset. For example, a slot 260 can align with an indicator 280 associated with a phasing or a shift of sixty degrees so that the locking tab 212 of a modular load-carrying segment 200b pairs with a notch 230 d a modular load-carrying segment 200a for positioning the hollow load 410 of the modular load-carrying segment 200b at a phasing or offset of sixty degrees with the hollow load 410 of the modular load-carrying segment 200a.
While Figure 4A illustrates a phasing or offset of sixty degrees, the present disclosure contemplates any degree of phasing or offset. For example, FIG. 4B illustrates a phase shift or a 120-degree offset of a shaped charge 410 of a modular load-carrying segment 200b with respect to the shaped charge 410 of a modular load-carrying segment 200a. Indicators 280 may indicate any one or more offsets or phasing.
FIG. 5A is a diagram illustrating an example of a modular charge spacer segment 500, according to aspects of the present disclosure. A modular load spacer segment 500 and a modular load carrier segment 200 can form a system to accommodate different organizations to create a configuration for any number of shaped charges 410 per foot. A modular load spacer segment 500 is similar to a modular load carrier segment 200 except that a modular load spacer segment 500 does not include a load opening 250. A modular load spacer segment 500 includes a tongue locking 210 and notches 230 so that it can be paired with one or more modular load carrying segments 200. A modular load spacer segment 500 can be of any length and can be used to increase the distance between a first shaped load , for example, a shaped charge 410 in FIG. 4A, of a first modular load-carrying segment 200 and a second shaped charge 410 of a second modular load-carrying segment 200.
Figure 5B is a diagram illustrating an exemplary configuration of modular load carrying segments 200 and a modular load spacer segment 500, in accordance with aspects of the present disclosure. A modular load spacer segment 500 can be disposed between a first modular load carrier segment 200a and a second modular load carrier segment 200b to space the shaped charges 410 associated with each modular load carrier segment 200 by a predetermined or desired distance. . While only one modular charge spacer segment 500 is illustrated in Figure 5B, the present disclosure contemplates any number of modular charge spacer segments 500 disposed between any two modular charge carrier segments 200.
FIG. 6A is a diagram illustrating an example of modular load carrying segment 600, according to aspects of the present disclosure. A modular load-carrying segment 600 is similar to a modular load-carrying segment 200. A modular load-carrying segment 600 may include a lower opening 620 to allow a lower portion (see an element 630 of Figure 6B) of a shaped charge 410 to protrude in order to engage or be compressed against a detonator cable (see item 910 in Figure 9). To improve efficiency and eliminate potential safety risks during loading and load reduction of shaped charges, for example, shaped charges 410 in Figure 4A, a modular load-carrying segment 600 may include lateral locking tabs 610 which engage with or mate with a corresponding receptacle or other mechanism (such as a notch or a matching mechanism) 640 of a shaped charge 410. Lateral locking tabs 610 can be any type of attachment, coupler, or other mechanism that allows the shaped charge 410 to be attached within the modular load-carrying segment 600. Lateral locking tabs 610 can deflect or flex while the shaped charge 410 is during loading in the modular load carrying segment 200. For a reduction in the load of the hollow load 410, a tool can be inserted between the hollow load 410 and the tongues lateral locking tabs 610 causing deflection or sagging of the lateral locking tabs 610 which releases the shaped charge 410. In one or more embodiments, lateral locking tabs 610 may not be required if a modular load-bearing segment 200 includes a slot 260.
FIG. 6B is a diagram illustrating an example of modular load-carrying segment 600 and a hollow load 410. A modular load-carrying segment 600 is illustrated with a hollow load 410 arranged inside a modular load-carrying segment 600 A lower portion 630 of the shaped charge 410 protrudes from the lower opening 620. The lower portion 630 may include a notch or a groove which allows a detonator cable (see element 910 in Figure 9) to enter in engagement or being compressed against the shaped charge 410.
Figure 7A is a diagram illustrating an example configuration of modular load carrying segments 200, in accordance with aspects of the present disclosure. Modular load bearing segments 200a and 200b are configured to be matched as indicated by the arrows to fix corresponding shaped charges 410. The shaped charges 410 can be embedded at least partially under an external surface 220 of the modular charge-carrying segments 200. A portion of one or more shaped charges 410 can extend at least partially on the male connector 270 and a portion d one or more shaped charges 410 may extend at least partially under a female connector 272.
FIG. 7B is a diagram illustrating an example of paired modular load bearing segments 200, according to aspects of the present disclosure. In one or more embodiments, when modular load-carrying segments 200a and 200b are paired or coupled together, a female connector 272 of a modular load-carrying segment 200a can overlap the hollow load portion 410 of a carrier segment of modular load 200b which is embedded at least partially under the external surface 220 of a modular load-carrying segment 200b, the male connector 270 of a modular load-carrying segment 200b can overlap the portion of the hollow load 410 by modular load-carrying segment 200a which is partially disposed under the female connector 272 of a modular load-carrying segment 200a or both to fix any or more shaped charges 410.
Figure 8 is a diagram illustrating an example of modular load carrying segments 200 and shaped charges 410, according to aspects of this disclosure. In one or more embodiments, shaped charges 410 may comprise two notches or planar portions 810a and 810b arranged at or spaced close to 180 degrees as illustrated in FIG. 8. When notches or planar portions 810 are not aligned with a female connector 272 and a male connector 270, the shaped charge 410 is in a locked position as illustrated by the shaped charge 410 of the modular load segment 200a. When planar portions 810 are aligned with a female connector 272 and a male connector 270, the shaped charge 410 is in an unlocked position.
In one or more embodiments, part of a punch tool assembly 34 may include a modular load carrying segment 200a which may include a first female connector 272 disposed at a first end of the modular load carrying segment 200a and a first male connector 270 at a second end of the modular load carrying segment 200a and a modular load carrying segment 200b which may similarly include a second female connector 272 disposed at a first end of the modular load carrying segment 200b and a second male connector 270 at a second end of the modular load carrying segment 200b. The first shaped charge 410 placed or positioned inside the modular load-carrying segment 200a illustrates a locked or fixed position of the first shaped charge 410. The first shaped charge 410 can be positioned or arranged inside the carrying segment of modular load 200a such that the notches or planar portions 810 are oblique with respect to or not completely aligned with the first female connector 272 and the first male connector 270. While FIG. 8 illustrates the notches or planar portions 810 positioned at a substantially ninety degree angle from a slot 260, the present disclosure contemplates any position of the notches or planar portions 810 oblique to the first female connector 272 and the first male connector 270 so that the second male connector 270 overlaps at least a portion of the first shaped charge 410 to place the first shaped charge 410 in a locked or fixed position, for example, for deployment at the bottom of a well. The second shaped charge 410 arranged or positioned inside a modular load bearing segment 200b illustrates an unlocked position for the second shaped charge 410. The notches or planar portions 810 of the second shaped charge 410 are aligned with the first female connector 272 of the modular load carrying segment 200a and the second male connector 270 of the modular load carrying segment 200b so that no overlap occurs between the second shaped charge 410 and the first female connector 272 and the second male connector 270 , for example, during charging or load reduction.
FIG. 9 is a diagram illustrating an example of configuration of modular load-carrying segments 600 and shaped charges 410, according to aspects of the present disclosure. A detonator cord or cable 910 can be coupled to the external surface 220 (as illustrated in FIG. 2) of the modular charge-carrying segments 600a and 600b, for example, via one or more arms 240. To fix the detonation cable 910 one or more arms 240 are fixed around the detonation cable 910 to compress the detonation cable 910 against an amplification channel 920 or a lower surface of the modular charge-carrying segment 600. One or more arms 240 can eliminate the need for any secondary component to secure the detonator cable 910 to the shaped charge 410. Arms 240 can provide a safety feature as no metal fastener is required to secure the detonator cable 910 which could damage the 910 detonator cable or injure personnel. In addition, arms 240 can allow the modular load carrying segment 600 to be molded as a single imitation. As illustrated, for example, in Figure 6B, a hollow charge 410 can be ballistically coupled to the detonator cable 910 via a lower portion 630 of the hollow charge 410 which extends through a lower opening 620. The detonator cable 910 can be ballistically coupled to a detonator (not shown) and the detonator can be electrically coupled to an information manipulation system, a power cable, or any other communication or signaling line that is configured to drive an electrical source adequate (for example, an electric current or an electrical signal) to cause the shaped charge 410 to ignite or explode.
