Abstract
Description
Technical Field
[0001] This utility model relates to the field of oil extraction machinery and equipment technology, specifically a perforation angle adjustment bracket. Background Technology
[0002] Perforation is an operation that uses specialized shaped charge perforators to create a shaped charge jet at a predetermined depth in the wellbore, allowing fluids from the formation to enter the perforation. It is widely used in oil and gas fields and coalfields, and sometimes in water extraction. Most oilfields commonly use shaped charge perforators. Historically, bullet-type perforators have been used, and some large international oil companies also use water jet perforators. A perforating gun is a combination of equipment and accessories used for perforating oil and gas wells. Currently, shaped charge perforating guns are the most widely used, utilizing the shaped charge effect to generate a focused jet that penetrates the formation. An existing perforation angle and azimuth positioning perforator (publication number: CN209724301U) has exhibited at least the following defects in use:
[0003] In the above scheme, by rotating the adjustment turntable, and with the transmission threaded rod and positioning bushing / bearing sleeve connected by a rotary connection and the transmission gear and transmission threaded rod connected by a threaded connection forming a worm gear transmission structure, the fixed oil pipe is rotated by rotating the adjustment turntable with the scale on the angle scale as a reference. This causes the structure on the perforating gun body to rotate downhole, achieving fixed-angle perforation. However, in actual use, the perforating pipe size is limited. When perforating a large area of formation, the adjustment turntable must be loosened to loosen the adjustment pipe, and then the perforating pipe must be inserted into a deeper formation before being fixed for subsequent perforation operations. This operation is quite cumbersome. Therefore, a perforation angle adjustment bracket was developed. Utility Model Content

[0022] Please see Figures 1-4 This utility model provides a technical solution:
[0023] A perforation angle adjustment bracket includes a fixed positioning frame 102. A rotating positioning frame 107 is snapped onto one side of the fixed positioning frame 102. An adjustment tube 201 is rotatably connected between the opposite sides of the rotating positioning frame 107 and the fixed positioning frame 102. The bottom end of the adjustment tube 201 is fixedly connected to a perforation tube 202. A fixed connecting seat 104 is fixedly connected to the bottom side of the fixed positioning frame 102. A support ring seat 106 is fixedly connected to the bottom side of the fixed connecting seat 104. Multiple evenly distributed rotating support rods 301 are rotatably connected to the bottom side of the support ring seat 106. A storage support frame 307 is slidably connected to the bottom outer edge of each rotating support rod 301. A support slider 305 is rotatably connected to the bottom end of each storage support frame 307. A support slide rail 306 is slidably connected to the outer edge of each support slider 305. A placement base 304 is fixedly connected to the bottom side of all support slide rails 306. In this embodiment, by synchronously sliding the support slider 305 in the corresponding support slide rail 306, the height of the fixed positioning frame 102 and the rotating positioning frame 107 are adjusted, thereby further controlling the depth of the perforation tube 202 in the formation.
[0024] Each rotating support rod 301 has a blocking connecting block 302 fixedly connected to its bottom end, and each storage support frame 307 has a blocking sliding piece 308 fixedly connected to its top end. The bottom side of each blocking sliding piece 308 is in contact with the top side of the corresponding blocking connecting block 302. Each blocking connecting block 302 has a support spring 303 fixedly connected to its bottom side, and one end of each support spring 303 is fixedly connected to the bottom inner wall of the corresponding storage support frame 307.
[0025] One side of the fixed positioning frame 102 is rotatably connected to the rotating positioning frame 107. A sliding annular groove 103 is respectively provided on the top side of both the fixed positioning frame 102 and the rotating positioning frame 107. The interiors of the two sliding annular grooves 103 are connected. A sliding ring strip 101 is slidably connected between the inner walls of each sliding annular groove 103. The opposite sides of the two sliding ring strips 101 are interlocked. A clamping ring 109 is fixedly connected to the top side of each of the two sliding ring strips 101. The opposite sides of the two clamping rings 109 are in close contact with the outer edge of the adjusting tube 201. A rotating handle 110 is fixedly connected to one side of one of the clamping rings 109. A set of evenly distributed graduations 108 are provided on the top sides of both the fixed positioning frame 102 and the rotating positioning frame 107. The graduations 108 are adapted to the rotating handle 110. In this embodiment, the clamping ring 109 is rotated by rotating the handle 110, which in turn rotates the adjusting tube 201. The angle of the adjusting tube 201 is observed through the scale 108. When separating the fixed positioning frame 102 and the rotating positioning frame 107, the connection point of the two sliding ring bars 101 needs to be rotated to the connection point of the fixed positioning frame 102 and the rotating positioning frame 107, so that the two sliding ring bars 101 separate as the fixed positioning frame 102 and the rotating positioning frame 107 separate.
[0026] Multiple evenly distributed rotating frames are fixedly connected to the opposite sides of the fixed positioning frame 102 and the rotating positioning frame 107. A positioning wheel 105 is rotatably connected between the inner walls of each rotating frame, and the surfaces of all positioning wheels 105 are in close contact with the outer edge of the adjusting tube 201, allowing the adjusting tube 201 to rotate. An adjusting side frame 401 is fixedly connected to one side of the base 304. A lifting cylinder 402 is fixedly connected to the top side of the adjusting side frame 401. An extension plate 403 is fixedly connected to the output end of the lifting cylinder 402. Multiple evenly distributed pushing rods 404 are fixedly connected to the bottom side of the extension plate 403, and the bottom ends of the pushing rods 404 are in close contact with the top side of the clamping ring 109. The operation of the lifting cylinder 402 pushes the clamping ring 109 downwards.
[0027] It should be noted that this utility model, as a perforation angle adjustment bracket, ensures that the perforation tube 202 is gathered at the center of the circular outline formed by all the rotating support rods 301 through the radially arranged rotating support rods 301 and the storage support frame 307 during use. With the help of the push rod 404 and the support spring 303, the perforation tube 202 is pressed into the deep formation by pressing down the push rod 404, thereby controlling the vertical position of the perforation tube 202. This allows it to adapt to a wider range of perforation operations without the need for secondary disassembly and assembly of the perforation tube 202, simplifying the processing flow and improving the efficiency of perforation operations.
