Description

Technical Field

[0001] The utility model relates to the technical field of perforating gun processing, in particular to a blind hole processing device for a perforating gun. Background Technique

[0002] A perforating gun is a tool used in oil fields for well completion or cementing. A perforating gun is a combination of equipment and its accessories used for perforating oil and gas wells. The more widely used one is the shaped charge perforating gun, which uses the shaped charge phenomenon of explosive to generate a shaped charge jet to penetrate the formation. The model of the perforating gun is represented by the outer diameter of the perforating gun. The selection of the perforating gun needs to be matched with the production casing and wall thickness, otherwise a stuck gun accident is likely to occur.

[0003] When the perforating gun is produced and processed, a processing device is required to process blind holes on the inner wall of the perforating gun. The current processing device fixes the perforating gun on a rotatable mechanism, and then processes the blind holes on the inner wall of the perforating gun by moving a turning tool. This method results in a relatively complex fixing mechanism for the perforating gun, and since the perforating gun rotates continuously, it is inconvenient to quickly clean the debris in the perforating gun during the processing. The debris inside the perforating gun is likely to affect the processing accuracy. Therefore, the utility model proposes a blind hole processing device for a perforating gun. Content of the Utility Model

[0004] The purpose of the utility model is to solve the defects existing in the prior art, and a blind hole processing device for a perforating gun is proposed.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme: a blind hole processing device for a perforating gun, including a workbench, on one side of the upper surface of the workbench, two installation components for installing the perforating gun are fixed. On the other side of the upper surface of the workbench, a first linear motor is horizontally installed. The surface of the moving end of the first linear motor is fixed with a vertical second linear motor. The surface of the moving end of the second linear motor is fixed with a processing component. A chip collection box and a suction fan are arranged at the bottom of the workbench. A filter screen is fixed inside the chip collection box. Feed pipes and exhaust pipes are respectively fixed on both sides of the chip collection box, and the feed pipes and exhaust pipes are respectively located on the upper and lower sides of the filter screen. The exhaust pipe is sleeved on the surface of the air inlet of the suction fan. A hose is sleeved on the surface of the feed pipe, and the other end of the hose is fixed with a side cover, and the side cover can be sleeved on the end surface of the perforating gun.

[0006] Further, the installation component includes a support platform fixed on the upper surface of the workbench, and on one side of the upper surface of the support platform, an L-shaped plate is fixed. The top of the L-shaped plate penetrates and is threadedly connected with a first screw rod.

[0007] Further, an arc-shaped groove is formed at the top of the support platform.

[0008] Further, the processing assembly includes a driving motor fixed to the surface of the moving end of the second linear motor. A horizontal shaft is fixed to the output end of the driving motor, and a turning tool is fixed to the other end of the horizontal shaft.

[0009] Further, two symmetrical second screws penetrate and are threadedly connected to the side wall of the side cover.

[0010] Further, a detachable top cover is fixed to the top surface of the chip collection box.

[0011] Advantages of the present utility model:

[0012] When the present utility model is in use, for this perforating gun blind hole processing equipment, a workbench, a mounting assembly, a first linear motor, a second linear motor, a processing assembly, a chip collection box, an exhaust fan, a hose, and a side cover are provided. The perforating gun can be horizontally fixed through the mounting assembly, and then the processing assembly is driven to move through the cooperation of the first linear motor and the second linear motor to realize the processing of the blind hole of the perforating gun. During this process, since the perforating gun is fixed, it is convenient to timely extract the metal chips generated during processing through the cooperation of the chip collection box and the exhaust fan, avoiding affecting the processing accuracy of the blind hole and making the chip collection more convenient. Secondly, the perforating gun is processed in a fixed manner, and the installation and disassembly are also simpler and more convenient, making the structure of the entire equipment simpler.

[0020] As Figures 1 - 3 shown, it relates to a blind hole processing device for a perforating gun, including a workbench 1. On one side of the upper surface of the workbench 1, two installation components 2 for installing the perforating gun 12 are fixed. On the other side of the upper surface of the workbench 1, a first linear motor 3 is horizontally installed. The surface of the moving end of the first linear motor 3 is fixed with a vertical second linear motor 4. The surface of the moving end of the second linear motor 4 is fixed with a machining component 5. A chip collecting box 6 and an exhaust fan 7 are provided at the bottom of the workbench 1. A filter screen 63 is fixed inside the chip collecting box 6. A feed pipe 61 and an exhaust pipe 62 are respectively fixed on both sides of the chip collecting box 6, and the feed pipe 61 and the exhaust pipe 62 are respectively located above and below the filter screen 63. The exhaust pipe 62 is sleeved on the surface of the air inlet of the exhaust fan 7. The surface of the feed pipe 61 is sleeved with a hose 9, and the other end of the hose 9 is fixed with a side cover 10, and the side cover 10 can be sleeved on the end surface of the perforating gun 12.

[0021] The installation component 2 includes a support platform 21 fixed on the upper surface of the workbench 1, and an L-shaped plate 23 is fixed on one side of the upper surface of the support platform 21. The top of the L-shaped plate 23 penetrates and is threadedly connected with a first screw 24.

[0022] After placing the perforating gun 12 on the surface of the support platform 21, the perforating gun 12 can be squeezed and fixed by turning the first screw 24.

[0023] An arc-shaped groove 22 is opened at the top of the support platform 21.

[0024] In this embodiment, the arc of the groove 22 matches the surface curvature of the perforating gun 12, which can better fix the perforating gun 12.

[0025] The processing assembly 5 includes a driving motor 51 fixed to the surface of the moving end of the second linear motor 4. A horizontal shaft 52 is fixed to the output end of the driving motor 51, and a turning tool 53 is fixed to the other end of the horizontal shaft 52.

[0026] The driving motor 51 can drive the horizontal shaft 52 and the turning tool 53 to rotate. By cooperating with the movement of the first linear motor 3 and the second linear motor 4, the turning tool 53 can be driven to move towards the perforating gun 12 or move up and down, so as to realize the processing of blind holes inside the perforating gun 12.

[0027] Two symmetric second screw rods 11 penetrate and are threadedly connected to the side wall of the side cover 10.

[0028] After the side cover 10 is covered on the surface of the end of the perforating gun 12, the side cover 10 can be fixed by screwing the second screw rod 11, so that the debris inside the perforating gun 12 can enter the inside of the chip collecting box 6 along the side cover 10 and the hose 9.

Then, fix the perforating gun 12 by screwing the first screw rod 24. Next, cover the side cover 10 on the surface of the end of the perforating gun 12 away from the processing assembly 5 and tighten the second screw rod 11 to fix the side cover 10. At this time, the driving motor 51 can drive the horizontal shaft 52 and the turning tool 53 to rotate, and then the first linear motor 3 and the second linear motor 4 cooperate to move, driving the rotating turning tool 53 to move, so that the turning tool 53 enters the inside of the perforating gun 12 to realize the processing of blind holes on the inner wall of the perforating gun 12. During the processing, start the exhaust fan 7, so the debris generated by the processing will enter the inside of the chip collecting box 6 along the hose 9, and the debris will be located on the surface of the filter screen 63. After the processing is completed, disassemble the top cover 8 to clean the debris on the surface of the filter screen 63.
