Description

Technical Field

[0001] This invention relates to the field of perforation gun technology, and more particularly to a perforation gun release device. Background Technology

[0002] A perforating gun is a tool used in oilfields for well completion or cementing. It is a combination of equipment and accessories used for perforating oil and gas wells. The most widely used type is the shaped charge perforating gun, which generates a shaped charge jet through the blasting phenomenon to penetrate the formation.

[0003] When existing perforating guns perform channel blasting in horizontal shafts, some of the debris generated by the channel blasting enters the space between the horizontal shaft and the perforating gun, while some debris passes through the attached... Figure 1 The stones are aligned with the hole and enter the perforating gun. The stones are stationary and provide a huge static friction force to the perforating gun, which creates a huge resistance when the perforating gun is pulled back. This is not conducive to the subsequent recovery of the perforating gun connected to the oil pipe, as well as the carried cables and oil pipes. Summary of the Invention

[0004] The purpose of this invention is to solve the problem in the prior art that the debris generated by the blasting of the perforating gun provides a huge static friction force on the perforating gun, which is not conducive to the subsequent recovery of the perforating gun connected to the oil pipe, as well as the carried cables and oil pipes. Therefore, a perforating gun release device is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A perforating gun release device includes a perforating gun body and a charge holder located within the perforating gun body. The perforating gun body has an alignment hole, and the charge holder has a detonator aligned with the alignment hole. An equipment tube is disposed between two perforating gun bodies. The inner walls of the perforating gun body and the charge holder are respectively provided with multiple first slots and second slots. The equipment tube is provided with multiple first blocks and second blocks that are respectively snapped into the first slots and second slots. A release component for connecting or separating the perforating gun body and the equipment tube is disposed in the equipment tube. A drive component that drives the perforating gun body and the charge holder to rotate in opposite directions via the release component is disposed in the equipment tube.

[0007] Preferably, one of the perforating gun bodies has a head end piece installed at the end furthest from the equipment tube, and the other perforating gun body has a tail end piece installed at the end furthest from the equipment tube.

[0008] Preferably, the release component includes a first mounting component and a second mounting component rotatably disposed in the device tube. A first rocker arm connected to a first locking block is rotatably mounted on the first mounting component, and a second rocker arm connected to a second locking block is rotatably mounted on the second mounting component. A first ball and a second ball are respectively fixedly connected to the other end of the first rocker arm and the other end of the second rocker arm. A first release component is slidably disposed in the device tube, and a second release component is integrally formed in the first release component.

[0009] Preferably, the device tube has a first circular groove that is rotatably connected to the first mounting component, and a return torsion spring is installed at the connection point between the first rocker arm and the first mounting component and at the connection point between the second rocker arm and the second mounting component.

[0010] Preferably, the device tube has a guide groove that is slidably connected to the first release member, and a push telescopic rod that is fixedly connected to the first release member is fixedly installed in the guide groove. The first release member and the second release member are both frustum shells, and the arc-shaped inner walls of the first release member and the second release member respectively move against the first sphere and the second sphere.

[0011] Preferably, the driving component includes a rotating gear ring rotatably disposed in the equipment tube, a driving gear and two driven gears rotatably disposed in the equipment tube, and one driven gear meshing with both the rotating gear ring and the driving gear, a connecting member fixedly connected between the rotating gear ring and the first mounting component, and a rotating shaft rotatably disposed in the equipment tube and fixedly connected to both the first mounting component and the driving gear.

[0012] Preferably, the equipment tube has a second circular groove that is rotatably connected to the rotating gear ring, and a communicating cavity is formed between the first circular groove and the second circular groove. The connector is rotatably installed in the communicating cavity. A dual-axis motor is fixedly installed in the equipment tube by a mounting truss, and both output ends of the dual-axis motor are fixedly connected to the rotating shaft.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] 1. When it is necessary to retract the two perforating gun bodies, if there is significant resistance during the retraction process, the present invention will activate the dual-axis motor to cause the rotating gear ring and the drive gear to rotate in opposite directions. At the same time, the rotating gear ring and the drive gear will drive the perforating gun body and the charging tube to rotate in opposite directions through the release component. This will allow the gravel between the horizontal wellbore and the perforating gun body, and between the perforating gun body and the charging tube, to move, thereby reducing the static friction of the gravel on the perforating gun body and thus achieving a labor-saving effect during the retraction of the two perforating gun bodies.

[0015] 2. When it is necessary to retract the two perforating gun bodies, if the perforating gun body and the propellant holder cannot rotate in opposite directions, the present invention will drive the auxiliary... Figure 2The first and second release components on the left move towards the equipment tube, thereby separating the first and second locking blocks from the first and second locking slots respectively, and releasing the attached components. Figure 2 The perforating gun body on the left reduces the weight of the remaining perforating gun body and equipment, reduces the contact area with the crushed stone, and thus reduces the static friction of the crushed stone on the remaining perforating gun body and equipment, so as to facilitate the subsequent recovery of the perforating gun connected to the oil pipe, as well as the carried cables and oil pipes.

[0016] 3. When assembling or separating the two perforating gun bodies, the present invention drives the first and second release members to move, so that the first and second balls move obliquely along the arc-shaped inner walls of the first and second release members, so that the first and second locking blocks enter or move away from the first and second locking slots respectively, so as to facilitate the rapid assembly or separation of the two perforating gun bodies. When the perforating gun body and the gun barrel are rotated in opposite directions, the first and second balls are rotated together with the perforating gun body and the gun barrel. Through the rolling friction between the arc-shaped inner walls of the first and second release members and the first and second balls, the frictional resistance of the first and second balls during movement is reduced, while maintaining the connection between the perforating gun body and the equipment tube.

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0027] Reference Figures 1-8 A perforating gun release device includes a perforating gun body 1 and a charge holder 2 located in the perforating gun body 1. The perforating gun body 1 is provided with an alignment hole 3, and the charge holder 2 is provided with a detonator 4 aligned with the alignment hole 3. An equipment tube 5 is provided between two perforating gun bodies 1, as shown in the attached diagram. Figure 1 As shown, an arc-shaped clamp is installed at the upper end of the equipment pipe 5. This clamp is used to hold the cable and connect it to the detonator 4. The detonator 4 is then remotely activated via the cable to detonate. The impact force generated by the explosion exits through the alignment hole 3, forming a channel in the horizontal shaft. Simultaneously, the debris generated by the explosion enters the horizontal shaft and the perforating gun body 1, as shown in the attached diagram. Figure 2 and attached Figure 3 As shown, the inner walls of the perforating gun body 1 and the inner walls of the charging tube 2 are respectively provided with multiple first slots 6 and second slots 7. The equipment tube 5 is provided with multiple first blocks 8 and second blocks 9 that are respectively snapped into the first slots 6 and the second slots 7. The equipment tube 5 is provided with a release component that allows the perforating gun body 1 and the equipment tube 5 to be quickly connected or separated through the first blocks 8 and the second blocks 9. At the same time, the equipment tube 5 is provided with a drive component that drives the perforating gun body 1 and the charging tube 2 to rotate in opposite directions through the release component, so as to move the gravel between the horizontal wellbore and the perforating gun body 1 and between the perforating gun body 1 and the charging tube 2, thereby reducing the static friction of the gravel on the perforating gun body 1, and thus achieving a labor-saving effect when retracting the two perforating gun bodies 1.

[0028] Preferably, as shown in the appendix Figure 1 and attached Figure 2 As shown, attached Figure 2A headpiece 10 is installed at the end of the left-side perforating gun body 1 furthest from the equipment tube 5. The headpiece 10 consists of two cylinders, which are inserted into the first slot 6 and the second slot 7 via locking blocks, so that the headpiece 10 can engage with the attached... Figure 2 The left-side perforating gun body 1 is connected to the sealing attachment. Figure 2 At the notch of the left perforating gun body 1, and with the two cylinders rotatably connected so that the two cylinders rotate with the perforating gun body 1 and the propellant holder 2, and attached... Figure 2 The right-side perforating gun body 1, at the end furthest from the equipment tube 5, is fitted with a tail end piece 11. This tail end piece 11 consists of two unidirectional cylindrical bodies and one counter-directional cylindrical body. The two unidirectional cylindrical bodies are inserted into the first slot 6 and the second slot 7 via a locking block, allowing the tail end piece 11 to engage with the attached... Figure 2 The right-side perforating gun body 1 is connected to the sealing attachment. Figure 2 The two cylindrical bodies are rotatably connected at the notch of the perforating gun body 1 on the right side, so that they can rotate with the perforating gun body 1 and the gun barrel 2. The reverse cylindrical body has internal threads and is connected to the oil pipe through the threads, so that the perforating gun body 1 and the equipment pipe 5 can be placed or pulled back by pulling the oil pipe.

[0029] Preferably, the release component includes a first mounting member 12 and a second mounting member 13 rotatably disposed in the device tube 5. A first rocker arm 14 connected to a first locking block 8 is rotatably mounted on the first mounting member 12, and a second rocker arm 15 connected to a second locking block 9 is rotatably mounted on the second mounting member 13. A first ball 17 and a second ball 18 are respectively fixedly connected to the other end of the first rocker arm 14 and the other end of the second rocker arm 15. A first release member 19 is slidably disposed in the device tube 5, and a second release member 20 is integrally formed in the first release member 19.

[0030] Preferably, the equipment pipe 5 has a first circular groove 21 that is rotatably connected to the first mounting member 12, and a return torsion spring 16 is installed at the connection between the first rocker arm 14 and the first mounting member 12 and the connection between the second rocker arm 15 and the second mounting member 13. Figure 6 When the upper first rocker arm 14 and the upper second rocker arm 15 are not subjected to external force, the ends of the upper first rocker arm 14 and the upper second rocker arm 15 connected to the upper first sphere 17 and the upper second sphere 18 are located at the attached... Figure 6 At the top, the other ends of the upper first rocker arm 14 and the upper second rocker arm 15 are located in the attached position. Figure 6 Below.

[0031] The equipment tube 5 is provided with a guide groove 22 that is slidably connected to the first release member 19 to guide the first release member 19 and the second release member 20 to move linearly. A push telescopic rod 23 that is fixedly connected to the first release member 19 is fixedly installed in the guide groove 22. The first release member 19 and the second release member 20 are both frustum shells, and the arc-shaped inner wall of the first release member 19 and the arc-shaped inner wall of the second release member 20 respectively move against the first ball 17 and the second ball 18.

[0032] It should be noted that, as shown in the attached document Figure 6 and attached Figure 8 As shown, the upper part of the arc-shaped inner wall of the first release member 19 and the arc-shaped inner wall of the second release member 20 slopes from left to right. That is, the leftmost point of the upper part of the arc-shaped inner wall of the first release member 19 and the leftmost point of the upper part of the arc-shaped inner wall of the second release member 20 are the highest points, while the rightmost point of the upper part of the upper part of the arc-shaped inner wall of the first release member 19 and the rightmost point of the upper part of the arc-shaped inner wall of the second release member 20 are the lowest points. By pushing the telescopic rod 23, the first release member 19 and the second release member 20 are moved towards the upper part of the arc-shaped inner wall. Figure 6 When moving to the left, the lowest point above the first release member 19 and the second release member 20 is located at the upper ends of the upper first ball 17 and the upper second ball 18. At the same time, the lowest point above the first release member 19 and the second release member 20 presses the upper first ball 17 and the upper second ball 18 downward, causing one end of the upper first rocker arm 14 and the upper second rocker arm 15 connected to the upper first ball 17 and the upper second ball 18 to deflect downward, while the other end of the upper first rocker arm 14 and the upper second rocker arm 15 deflects upward, as shown in the attached figure. Figure 2 As shown, the first locking block 8 and the second locking block 9 are respectively inserted into the first locking slot 6 and the second locking slot 7 and snapped together to complete the connection between the perforating gun body 1 and the equipment tube 5.

[0033] And by pushing the telescopic rod 23, the first release member 19 and the second release member 20 are moved towards the attachment Figure 6 When moving to the right, the highest point above the first release member 19 and the second release member 20 is located at the upper end of the upper first ball 17 and the upper second ball 18. The upper first rocker arm 14 and the upper second rocker arm 15 are connected to the upper first ball 17 and the upper second ball 18 by the elastic force of the return torsion spring 16, and the ends of the upper first rocker arm 14 and the upper second rocker arm 15 are deflected upward, that is, the upper first ball 17 and the upper second ball 18 are respectively abutted against the highest point above the first release member 19 and the second release member 20. The other ends of the upper first rocker arm 14 and the upper second rocker arm 15 are deflected downward, so that the first locking block 8 and the second locking block 9 are separated from the first locking groove 6 and the second locking groove 7 respectively, thereby releasing the connection between the perforating gun body 1 and the equipment tube 5.

[0034] Preferably, the driving component includes a rotating gear ring 24 rotatably disposed in the device tube 5. A driving gear 25 and two driven gears 26 are rotatably disposed in the device tube 5, and each driven gear 26 meshes with both the rotating gear ring 24 and the driving gear 25. Therefore, when the driving gear 25 rotates, it causes the driving gear 25 and the rotating gear ring 24 to rotate in opposite directions. A connecting member 27 is fixedly connected between the rotating gear ring 24 and the first mounting member 12, causing the rotating gear ring 24 and the first mounting member 12 to rotate in the same direction. A rotating shaft 28 is rotatably disposed in the device tube 5 and is fixedly connected to both the first mounting member 12 and the driving gear 25, causing the driving gear 25 and the second mounting member 13 to rotate in the same direction, thereby causing the first mounting member 12 and the second mounting member 13 to rotate in opposite directions. The connection between the rotating shaft 28 and the first release member 19 and the second release member 20 is a rotatable connection to prevent the rotating shaft 28 from driving the first release member 19 and the second release member 20 when it rotates.

[0035] Preferably, as shown in the appendix Figure 4 As shown, the equipment tube 5 has a second circular groove 30 that is rotatably connected to the rotating gear ring 24. A communicating cavity 31 is formed between the first circular groove 21 and the second circular groove 30. The connector 27 is rotatably installed in the communicating cavity 31. A dual-axis motor 29 is fixedly installed in the equipment tube 5 through a mounting truss 32. The driven gear 26 and the rotating shaft 28 are also installed in the equipment tube 5 through the mounting truss 32. Both output ends of the dual-axis motor 29 are fixedly connected to the rotating shaft 28. The dual-axis motor 29 is a co-rotating dual-axis motor, that is, the output ends of the dual-axis motor 29 rotate in the same direction, so that the rotating shafts 28 on both sides of the dual-axis motor 29 rotate in the same direction. The dual-axis motor 29 and the push telescopic rod 23 can be connected to a cable, so that the dual-axis motor 29 and the push telescopic rod 23 can be remotely started through the cable.

[0036] It should be noted that when it is necessary to retract the two perforating gun bodies 1, if there is significant resistance during the retraction process, the dual-shaft motor 29 is activated to cause the rotating gear ring 24 and the drive gear 25 to rotate in opposite directions. Simultaneously, the rotating gear ring 24 and the drive gear 25 drive the perforating gun body 1 and the charging tube 2 to rotate in opposite directions. This allows the debris between the horizontal wellbore and the perforating gun body 1, and between the perforating gun body 1 and the charging tube 2, to move, preventing the debris in these two locations from providing significant static friction to the perforating gun body 1 due to its static state. The process of retracting the two perforating gun bodies 1 saves effort; however, for the gravel located between the perforating gun body 1 and the propellant tube 2, if the perforating gun body 1 and the propellant tube 2 rotate in the same direction, there is no relative rotation between the perforating gun body 1 and the propellant tube 2, which slightly pushes the gravel at this point and reduces the static friction provided by the gravel. Therefore, the perforating gun body 1 and the propellant tube 2 rotate in opposite directions, so that the perforating gun body 1 and the propellant tube 2 rotate relative to each other, thereby violently pushing the gravel at this point and greatly reducing the static friction provided by the gravel at this point.

[0037] If the perforating gun body 1 and the propellant tube 2 cannot rotate in opposite directions, it indicates that the static friction provided by the crushed stone severely affects the retraction of the equipment tube 5, cable, and oil pipe, and drives the attached... Figure 2 The first release member 19 and the second release member 20 on the left move toward the equipment tube 5, causing one end of the first rocker arm 14 and the second rocker arm 15 to deflect away from the inner wall of the perforating gun body 1 and the inner wall of the propellant tube 2, respectively. This causes the first locking block 8 and the second locking block 9 to separate from the first locking groove 6 and the second locking groove 7, respectively, and release the attached... Figure 2 The left-side perforating gun body 1 reduces the weight of the remaining perforating gun body 1 and equipment, reduces the contact area with the crushed stone, and thus reduces the static friction force of the crushed stone on the remaining perforating gun body 1 and equipment. Then, it drives the remaining perforating gun body 1 and the charging tube 2 to rotate in the opposite direction, further reducing the static friction force of the crushed stone on the remaining perforating gun body 1 and equipment, so as to facilitate the subsequent recovery of the remaining perforating gun body 1 and the carried cables, oil pipes and equipment pipes 5. The perforating gun body 1 and the charging tube 2 are made of soluble aluminum alloy, so that the released perforating gun body 1 and the charging tube 2 can dissolve in the horizontal wellbore.

[0038] When the perforating gun body 1 and the charging tube 2 rotate in opposite directions, the first ball 17 and the second ball 18 rotate together with the perforating gun body 1 and the charging tube 2. They roll and rub against the first ball 17 and the second ball 18 through the arc-shaped inner wall of the first release member 19 and the arc-shaped inner wall of the second release member 20. This reduces the frictional resistance of the first ball 17 and the second ball 18 during their movement while maintaining the connection between the perforating gun body 1 and the equipment tube 5.

[0039] The functional principle of this invention can be explained through the following operational methods:

[0040] When assembling the two perforating gun bodies 1, the first slot 6 and the second slot 7 are aligned with the first block 8 and the second block 9 respectively, and the push telescopic rod 23 is activated to drive the first release member 19 and the second release member 20 to move toward the perforating gun body 1, so that one end of the first rocker arm 14 and the second rocker arm 15 deflects toward the inner wall of the perforating gun body 1 and the inner wall of the gun barrel 2 respectively, thereby allowing the first block 8 and the second block 9 to enter the first slot 6 and the second slot 7 respectively and be snapped together, so as to complete the assembly of the two perforating gun bodies 1;

[0041] The two assembled perforating gun bodies 1 are then placed into the horizontal shaft, and the detonators 4 of each perforating gun body 1 are activated to create a channel in the horizontal shaft. Simultaneously, the debris generated by the explosion enters the horizontal shaft and the perforating gun body 1. If significant resistance is encountered during the retraction of the two perforating gun bodies 1, the dual-shaft motor 29 is activated. The dual-shaft motor 29 drives the drive gear 25 to rotate via the rotating shaft 28. Since both the drive gear 25 and the driven gear 26 mesh with the rotating gear ring 24, the rotating gear ring 24 and the drive gear 25 rotate in opposite directions. Simultaneously, the rotating gear ring 24 and the drive gear 25 drive the perforating gun body 1 and the charging tube 2 to rotate in opposite directions, thus moving the debris between the horizontal shaft and the perforating gun body 1, and between the perforating gun body 1 and the charging tube 2, reducing the static friction of the debris on the perforating gun body 1. If the perforating gun body 1 and the charging tube 2 cannot rotate in opposite directions, the auxiliary... Figure 2 The first release member 19 and the second release member 20 on the left move toward the equipment tube 5, causing one end of the first rocker arm 14 and the second rocker arm 15 to deflect away from the inner wall of the perforating gun body 1 and the inner wall of the propellant tube 2, respectively. This causes the first locking block 8 and the second locking block 9 to separate from the first locking groove 6 and the second locking groove 7, respectively, and release the attached... Figure 2 The perforating gun body 1 on the left reduces the weight of the remaining perforating gun body 1 and equipment, reduces the contact area with the crushed stone, and thus reduces the static friction force of the crushed stone on the remaining perforating gun body 1 and equipment.
