Technical Field

[0001] This utility model relates to the field of oil perforation technology, and in particular to a perforation device for oil perforation. Background Technology

[0002] In oil extraction, perforation technology is a crucial part of well completion operations. A perforating gun creates a channel between the well casing and the formation, allowing oil and gas to flow smoothly into the wellbore. Before use, the perforating gun requires precise drilling to ensure accurate positioning and effective detonation of the perforating cartridge. However, existing oil perforating gun drilling devices often leave burrs, protrusions, or unevenness at the hole edges after drilling. These defects can make perforating cartridge installation difficult and even affect perforation efficiency and operational safety. Utility Model Content

[0003] The purpose of this invention is to solve the problems in the existing oil perforation drilling devices, such as burrs, protrusions or unevenness at the edge of the hole after drilling. These defects may lead to difficulties in installing the perforation projectile, and even affect the perforation effect and operational safety. The invention provides an oil perforation drilling device.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a drilling device for oil perforation, comprising a drilling apparatus, a quick-release mechanism sleeved on the outer surface of the drilling apparatus, a grinding mechanism fixedly connected to one end of the quick-release mechanism, the grinding mechanism comprising a housing, a fixing frame fixedly connected to the outer surface of the housing, a motor sleeved on the outer surface of the fixing frame, a first gear fixedly connected to one end of the motor, the first gear meshing with a second gear, a fixing tube fixedly connected to the inner wall of the second gear, a bearing fixedly connected to one end of the fixing tube, the bearing being placed inside the housing and fixedly connected to the housing, and a grinding disc sleeved on the inner wall of the fixing tube.

[0005] In a preferred embodiment, the quick-release mechanism includes a support rod, one end of which has a locking hole. A buckle is fitted onto the inner wall of the locking hole, one end of which is fixedly connected to a moving block. A second spring is fixedly connected to one side of the buckle, and one end of the second spring is fixedly connected to the inner wall of the drilling device.

[0006] In one preferred embodiment, one end of the support rod is engaged with the inner wall of the drilling device.

[0007] In a preferred embodiment, the inner wall of the second gear is provided with a groove, a first spring is fixedly connected to the inner wall of the groove, a locking block is fixedly connected to one end of the first spring, and a slider is fixedly connected to one end of the locking block.

[0008] In a preferred embodiment, the outer surface of the buckle engages with the inner wall of the buckle hole.

[0009] In a preferred embodiment, the slider is slidably connected to the groove, and the locking block is engaged with the inner wall of the grinding disc through the fixing tube.

[0010] In a preferred embodiment, the outer surface of the grinding disc is engaged with the inner wall of the fixing tube.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] This invention uses a drilling device to drill holes in the surface of a perforating gun. A quick-release mechanism provides fixed support for a grinding mechanism, which then grinds the drilled areas on the perforating gun surface.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0023] like Figures 1-4 As shown, this utility model provides a technical solution: a drilling device for oil perforation, including a drilling device 1, a quick-release mechanism 3 sleeved on the outer surface of the drilling device 1, a grinding mechanism 2 fixedly connected to one end of the quick-release mechanism 3, the grinding mechanism 2 including a housing 21, a fixing frame 22 fixedly connected to the outer surface of the housing 21, a motor 23 sleeved on the outer surface of the fixing frame 22, a first gear 24 fixedly connected to one end of the motor 23, the first gear 24 meshing with a second gear 25, a fixing tube 26 fixedly connected to the inner wall of the second gear 25, a bearing 28 fixedly connected to one end of the fixing tube 26, the bearing 28 placed inside the housing 21, the bearing 28 fixedly connected to the housing 21, a grinding disc 27 sleeved on the inner wall of the fixing tube 26, a sliding groove opened on the inner wall of the second gear 25, a first spring 29 fixedly connected to the inner wall of the sliding groove, a locking block 202 fixedly connected to one end of the first spring 29, and a slider 201 fixedly connected to one end of the locking block 202.

[0024] In this embodiment, the perforating gun is perforated by a perforating device 1, and the perforated area on the surface of the perforating gun is polished by a polishing mechanism. The housing 21 provides a good installation environment for other components. The motor 23 is fixed by a mounting bracket 22. The rotation of the motor 23 drives the first gear 24 to rotate. Since the first gear 24 is meshed with the second gear 25, the rotation of the first gear 24 simultaneously drives the rotation of the second gear 25. Furthermore, the fixing tube 26 is fixedly connected to the bearing 28, and the bearing 28 is fixedly connected to the housing 21, thus completing the fixing of the fixing tube 26. The fixed connection between the fixing tube 26 and the second gear 25 ensures that the second gear 25 will not fall off. The polishing disc 27 engages with the fixing tube 26 to complete the polishing process. The grinding disc 27 is fixed by grinding the perforated area on the surface of the perforating gun, improving work efficiency. When the grinding disc 27 is damaged, the sliding slider 201 drives the locking block 202 to move into the groove, thereby separating the locking block 202 from the inner wall of the grinding disc 27, releasing the limitation on the grinding disc 27, and completing the disassembly of the grinding disc 27. When installing a new grinding disc 27, the grinding disc 27 is inserted into the fixed tube 26. The surface of the grinding disc 27 will press the locking block 202 and compress the first spring 29. After the grinding disc 27 is completely inserted into the fixed tube 26, the first spring 29 will rebound and drive the locking block 202 to reset, so that the locking block 202 engages with the inside of the grinding disc 27, completing the fixation of the grinding disc 27 and ensuring that the grinding work can proceed normally. Example 2

[0025] like Figures 1-5 As shown, the quick-release mechanism 3 includes a support rod 31, one end of which has a locking hole 32. A buckle 34 is fitted into the inner wall of the locking hole 32, and the outer surface of the buckle 34 engages with the inner wall of the locking hole 32. A moving block 35 is fixedly connected to one end of the buckle 34, and a second spring 33 is fixedly connected to one side of the buckle 34. One end of the second spring 33 is fixedly connected to the inner wall of the drilling device 1, and one end of the support rod 31 engages with the inner wall of the drilling device 1.

[0026] In this embodiment, the quick-release mechanism 3 provides support and fixation for the grinding mechanism 2, and the support rod 31 provides fixed support for the housing 21. The support rod 31 is fixed by engaging with the buckle 34 through the locking hole 32. When the quick-release mechanism 3 needs to be disassembled, the buckle 34 is separated from the locking hole 32 by pulling the moving block 35, thereby releasing the fixation of the support rod 31 and completing the disassembly of the quick-release mechanism 3. When the buckle 34 moves, it will compress the second spring 33. After the disassembly is completed, the buckle 34 will be reset by the rebound of the second spring 33.

[0027] Working principle:

[0028] like Figures 1-5 As shown, in this utility model, the worker starts the drilling device 1, and the laser of the drilling device 1 drills holes on the surface of the perforating gun. The perforated area needs to be polished. The worker engages the quick-release mechanism 3 with the drilling device 1. When the support rod 31 is engaged with the drilling device 1, one end of the support rod 31 is pressed against the buckle 34, thereby driving the second spring 33 to compress. When the buckle hole 32 is aligned with the buckle 34, the rebound of the second spring 33 drives the buckle 34 to reset, thereby engaging the buckle 34 with the buckle hole 32, completing the fixation of the support rod 31. The quick-release mechanism 3 is fixedly connected to the polishing mechanism 2, thereby completing the fixation of the polishing mechanism 2.

[0029] When grinding the perforated area of ​​the perforating gun, the motor 23 is fixed by the fixing bracket 22. The rotation of the motor 23 drives the first gear 24 to rotate. Since the first gear 24 is meshed with the second gear 25, the rotation of the first gear 24 drives the rotation of the second gear 25. The fixing tube 26 is fixedly connected to the bearing 28, and the bearing 28 is fixedly connected to the housing 21, thus completing the fixing of the fixing tube 26. The fixing tube 26 and the second gear 25 are fixedly connected, ensuring that the second gear 25 will not fall off. The grinding disc 27 is fixed by engaging with the fixing tube 26. The grinding disc 27 is then used to grind the perforated area on the surface of the perforating gun. To improve work efficiency, when the grinding disc 27 is damaged, the sliding slider 201 drives the locking block 202 to move into the groove, thereby separating the locking block 202 from the inner wall of the grinding disc 27, releasing the limitation on the grinding disc 27, and completing the disassembly of the grinding disc 27. When installing a new grinding disc 27, the grinding disc 27 is inserted into the inside of the fixing tube 26. The surface of the grinding disc 27 will press against the locking block 202 and compress the first spring 29. After the grinding disc 27 is completely inserted into the inside of the fixing tube 26, the first spring 29 will rebound and drive the locking block 202 to reset, so that the locking block 202 engages with the inside of the grinding disc 27, completing the fixation of the grinding disc 27 and ensuring that the grinding work proceeds normally.

[0030] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
