AI Technical Summary
Existing oil perforating projectiles lack an effective fixing mechanism when tilted and fixed, resulting in positioning difficulties and failing to meet the requirement of a certain firing angle between the perforating projectile and the radial plane of the projectile holder tube in the new process.
An oilfield metal perforation projectile holder is adopted, which is designed with an adjustment mechanism, including a placement cylinder, a connecting rod, a connecting column, a knob, a worm gear, and a worm. The angle of the projectile is adjusted and fixed by the meshing of the worm gear and the worm. Combined with a limit ring and a fixing mechanism, the stable positioning of the projectile is ensured.
This technology enables the perforating projectile to be stably tilted and fixed, meeting the requirement of a certain firing angle between the perforating projectile and the radial plane of the projectile holder tube in the new process, thus improving the reliability and efficiency of the perforation operation.

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0019] like Figures 1-4 As shown, a metal perforation cartridge holder for oil fields includes a cartridge holder 1, which has several mounting holes 2 and several adjustment mechanisms 3 inside the cartridge holder 1, with a cartridge body 4 inside the adjustment mechanism 3.
[0020] In this embodiment, the adjustment mechanism 3 includes a placement cylinder 301, a connecting rod 302, a connecting column 303, a knob 304, a worm gear 305, and a worm 306. One end of the connecting rod 302 is fixedly connected to the left and right sides of the placement cylinder 301, and the other end of the connecting rod 302 is rotatably connected to the inner wall of the cartridge holder 1. The middle part of the worm gear 305 is fixedly connected to the outer periphery of the connecting rod 302. The upper end of the worm 306 is fixedly connected to the lower end of the connecting column 303. The worm gear 305 and the worm 306 mesh with each other. The outer periphery of the connecting column 303 passes through and is rotatably connected to the wall shell of the cartridge holder 1. The middle part of the knob 304 is fixedly connected to the upper end of the connecting column 303. The mounting holes 2 are spirally and evenly spaced on the side wall of the cartridge holder 1. The adjustment mechanism 3 and the mounting holes 2 correspond one-to-one.
[0021] Specifically, by rotating the knob 304, the connecting column 303 drives the worm gear 306 to rotate, which in turn drives the worm wheel 305 to rotate the connecting rod 302 connected to it, thereby adjusting the orientation of the placement cylinder 301, and thus adjusting the orientation of the projectile 4. Furthermore, because the worm wheel 305 and the worm gear 306 have self-locking properties, the angle of the adjusted placement cylinder 301 is fixed.
[0022] In this embodiment, a limiting ring 6 is provided at the lower part of the placement cylinder 301, and a fixing mechanism 5 is provided inside the placement cylinder 301. The fixing mechanism 5 includes a cavity 501, a clamping block 502 and a spring rod 503. The cavity 501 is opened around the placement cylinder 301. The clamping block 502 is slidably connected to the cavity 501. One end of the spring rod 503 is fixedly connected to the inner wall of the cavity 501, and the other end of the spring rod 503 is fixedly connected to the inner wall of the clamping block 502. The clamping block 502 is wrapped with an anti-slip rubber pad.
[0023] Specifically, the projectile 4 is pressed down onto the placement cylinder 301, causing the bottom edge of the projectile 4 to press against the upper inclined edge of the clamping block 502, thereby causing the clamping block 502 to compress the spring rod 503 and retract into the cavity 501, allowing the projectile 4 to continue to descend. Then, the spring rod 503 causes the clamping block 502 to press and fix the projectile 4.
[0024] Working principle:
[0025] Pressing the projectile 4 against the placement cylinder 301 causes the bottom edge of the projectile 4 to press against the upper inclined edge of the clamping block 502, thereby causing the clamping block 502 to compress the spring rod 503 and retract into the cavity 501, allowing the projectile 4 to continue to descend. Then, the spring rod 503 causes the clamping block 502 to press and fix the projectile 4. By rotating the knob 304, the connecting column 303 drives the worm gear 306 to rotate, which in turn causes the worm wheel 305 to drive the connected connecting rod 302 to rotate, thereby adjusting the orientation of the placement cylinder 301, and thus the orientation of the projectile 4. Furthermore, because the worm wheel 305 and the worm gear 306 have self-locking properties, the angle of the placement cylinder 301 is fixed after adjustment.
