Description

Technical Field

[0001] This invention belongs to the technical field of drilling and oil production equipment, specifically a drilling and completion integrated tool and drilling and completion operation method. Background Technology

[0002] Drilling and oil production is a core part of the petroleum industry. After drilling is completed and oil and gas are collected, a filtration system is used to filter out mud, gravel, and other foreign objects from the oil and gas entering the tubing. As filtration proceeds, the accumulated mud and gravel will adhere to the outside of the tubing, which will block the filter holes. This will make it difficult for oil and gas to pass through the filter holes and enter the tubing, thus interrupting the collection of oil and gas and making it difficult for oil production to proceed normally.

[0003] Therefore, the present invention provides an integrated drilling and completion tool and a drilling and completion operation method. Summary of the Invention

[0015] Preferably, the top of the drill bit is provided with a pair of reinforcing grooves, and the bottom of the telescopic cover is fixedly connected with a reinforcing block that is slidably connected to the reinforcing grooves.

[0016] Preferably, the inner wall of the scraper ring is provided with multiple connecting grooves and roller grooves. A magnetic block is fixedly connected to the inner side wall of the connecting groove. A discharge groove is provided on the inner bottom wall of the connecting groove. A roller is rotatably connected inside the roller groove. Multiple sliding grooves are provided on the roller. A metal block is slidably connected inside the sliding groove. A second spring is fixedly connected to the side of the metal block. A push-pull rod one and a push-pull rod two are movably inserted inside the roller. An adjustment groove is provided on the push-pull rod one. The push-pull rod two is movably inserted inside the adjustment groove. A pair of metal blocks in the vertical direction are fixedly connected to the push-pull rod two. A pair of metal blocks in the horizontal direction are fixedly connected to the push-pull rod one.

[0017] Preferably, the end of the second spring away from the metal block is fixedly connected to the inner wall of the slide groove, the outer sides of the first and second push-pull rods are in contact with the inner wall of the second spring, and the inside of the roller is provided with a push-pull groove 1 and a push-pull groove 2 that are movably inserted into the first and second push-pull rods. A pair of slide grooves in the horizontal direction communicate with the first push-pull groove, and a pair of slide grooves in the vertical direction communicate with the second push-pull groove.

[0018] A drilling and completion operation method, which uses the aforementioned integrated drilling and completion tool, includes the following steps:

[0019] S1: After drilling is completed, the telescopic cover is pressed against the borehole wall, and the oil and gas will enter the oil inlet pipe through the filter hole.

[0020] S2: Start the electric push rod one to move the scraper ring on the oil inlet pipe to scrape off the dirt and foreign matter adhering to it;

[0021] S3: When the scraper ring moves upward, the magnetic block will attract the metal block, creating a negative pressure in the chute to clear the filter holes.

[0022] The beneficial effects of this invention are as follows:

[0023] 1. The present invention discloses an integrated drilling and completion tool and a drilling and completion operation method. Drilling is performed using a drill bit. After drilling, one side of the telescopic cover is brought into contact with the well wall. During the insertion of the inlet pipe into the well, the telescopic cover can wrap around the filter hole, preventing foreign objects from entering. After drilling, the telescopic cover is opened to support the well wall, preventing collapse. Oil and gas then enter the filter hole between the pair of telescopic covers, filtering out the mud and gravel mixed within before entering the inlet pipe. During the oil and gas filtration and collection process, personnel periodically activate the electric push rod two, causing its telescopic end to pull the mounting block and all its mechanisms upwards. This causes the scraper ring to move upwards close to the inlet pipe, scraping away the mud and gravel adhering to the filter hole, preventing blockage and allowing oil and gas to smoothly enter the inlet pipe, thus ensuring the smooth progress of oil production.

[0024] 2. The drilling and completion integrated tool and drilling and completion operation method of the present invention, when the scraper ring pushes the mud and gravel adhering to the outside of the inlet pipe upward, the top of the scraper ring will push the elastic ring, causing it to undergo elastic deformation and expand. When it expands, its bottom inclined surface will rub against the top of the scraper ring, thereby scraping off the mud and gravel accumulated on the top of the scraper ring, which can then quickly separate the mud and debris from the scraper ring and let them fall, thus facilitating the cleaning of the mud and gravel on the scraper ring.

[0025] 3. The drilling and completion integrated tool and drilling and completion operation method of the present invention, when the metal block rotates to a position horizontally opposite to the magnetic block, under the magnetic attraction of the magnetic block on the metal block, will pull the push-pull rod one or push-pull rod two to move closer to it, thereby causing the push-pull rod one or push-pull rod two to drive the metal block at the other end to move together. At this time, since the sluice is horizontally opposite to the magnetic block and away from the magnetic block, it will be directly opposite the filter hole. Therefore, when the metal block moves in the sluice and approaches the magnetic block, a negative pressure will be generated in the sluice near the oil inlet pipe. Under the action of the negative pressure, the mud and gravel in the filter hole can be sucked up and brought into the sluice. This makes it less likely that the speed of oil and gas entering the oil inlet pipe will be reduced due to the mud and gravel entering the filter hole, and the mud and gravel will block the filter hole.

[0038] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0039] Example 1: As Figure 1-2 and Figure 3 as well as Figure 8 As shown in the figure, an integrated drilling and completion tool according to an embodiment of the present invention includes a drill bit 1, an oil inlet pipe 2 is fixedly connected to the top of the drill bit 1, and a filter hole 3 is provided on the oil inlet pipe 2;

[0040] A pair of telescopic covers 4 are fitted on the outside of the oil inlet pipe 2. A pair of symmetrically distributed electric push rods 5 are fixedly connected to the surface of the oil inlet pipe 2. The telescopic ends of the electric push rods 5 are fixedly connected to the telescopic covers 4.

[0041] The telescopic cover 4 has a vertical groove 6 on its inner wall. An electric push rod 7 is fixedly connected to the inner top wall of the vertical groove 6. An installation block 8 is fixedly connected to the telescopic end of the electric push rod 7.

[0042] A spring 9 is fixedly connected to the side of the mounting block 8. A scraper ring 10 is fixedly connected to the end of the spring 9 away from the mounting block 8. When the scraper ring 10 abuts against the outside of the oil inlet pipe 2, the spring 9 is still in a contracted state. Therefore, it can continuously push the scraper ring 10 so that the scraper ring 10 fits tightly against the oil inlet pipe 2, thereby ensuring the scraper ring 10's scraping effect on the oil inlet pipe 2.

[0043] In the initial state, the spring 9 is in a contracted state, and the pair of scraper rings 10 are both sleeved on the outside of the oil inlet pipe 2 and are symmetrically distributed on both sides of the oil inlet pipe 2.

[0044] In the existing technology, when collecting oil and gas after drilling, a filtration mechanism is used to filter mud and foreign objects such as gravel in the oil and gas that enter the tubing. As filtration proceeds, the accumulated mud and gravel will adhere to the outside of the tubing, which will block the filter hole 3. This will make it difficult for oil and gas to pass through the filter hole 3 and enter the tubing, thus interrupting the collection of oil and gas and making it difficult for oil production to proceed normally.

[0045] In use, this invention utilizes drill bit 1 for drilling. After drilling is completed, the electric push rod 5 is activated, causing its telescopic end to push the telescopic cover 4 to move away from the oil inlet pipe 2 (in conjunction with...). Figure 2 As shown), this causes the telescopic cover 4 to move toward the well wall until the side of the telescopic cover 4 away from the oil inlet pipe 2 is in contact with the well wall;

[0046] During the process of inserting the inlet pipe 2 into the well, the telescopic cover 4 can wrap the filter hole 3 to prevent foreign objects from entering it. After drilling is completed, the telescopic cover 4 can be opened to support the well wall and prevent it from collapsing.

[0047] Afterwards, the oil and gas will enter the filter hole 3 between a pair of telescopic shields 4, and then filter the mud and gravel mixed inside through the filter hole 3 before entering the oil inlet pipe 2.

[0048] During the oil and gas filtration and collection process, personnel need to periodically activate the electric push rod 7, causing its telescopic end to pull the mounting block 8 and all its mechanisms upwards together. This causes the scraper ring 10 to move upwards on the oil inlet pipe 2. The scraper ring 10 is used to scrape the mud and gravel adhering to the filter holes 3, making the filter holes 3 less likely to be blocked by mud and gravel. This allows oil and gas to enter the oil inlet pipe 2 smoothly, thus ensuring the smooth progress of oil extraction.

[0049] like Figure 7 and Figure 9As shown, a plug rod 11 is fixedly connected to the side of the mounting block 8, and a plug groove 12 adapted to the plug rod 11 is provided on the scraper ring 10.

[0050] When the scraper ring 10 is moved together by the spring 9, the plug rod 11 can support both of them, improving their stability during movement.

[0051] like Figure 7 and Figure 9 As shown, the insertion rod 11 is inserted into the insertion slot 12 and the spring 9. The bottom of the scraper ring 10 abuts against the top of the drill bit 1, thus improving the stability of the scraper ring 10 and making it less likely to rotate on the insertion rod 11 when moving.

[0052] like Figure 7 and Figure 9 As shown, the surface of the plug rod 11 is in contact with the inner wall of the spring-9. The inner diameter of the spring-9 is larger than the diameter of the plug groove 12, which facilitates the scraper ring 10 to squeeze the spring-9, causing the spring-9 to contract between the mounting block 8 and the scraper ring 10.

[0053] like Figure 4 As shown, a sleeve ring 13 is fixedly connected to the surface of the oil inlet pipe 2, and a pair of connecting rods 14 are fixedly connected to the outer side of the sleeve ring 13. The bottom of the pair of connecting rods 14 is fixedly connected to the same elastic ring 15.

[0054] The outer shape of the scraper ring 10 is trapezoidal, and the inner ring of the elastic ring 15 has a conical structure (combined with...). Figure 4 and Figure 5 As shown in the figure, under the thrust of the scraper ring 10, the elastic ring 15 is more likely to undergo elastic deformation and expand, which makes it easier for the scraper ring 10 to move up and down through the elastic ring 15.

[0055] When the scraper ring 10 pushes the mud and gravel adhering to the outside of the oil inlet pipe 2 upward, the top of the scraper ring 10 will push the elastic ring 15, causing it to undergo elastic deformation and expand. When it expands, its bottom inclined surface will rub against the top of the scraper ring 10, thereby scraping off the mud and gravel accumulated on the top of the scraper ring 10, which in turn enables the mud and debris to quickly separate from the scraper ring 10 and fall down.

[0056] like Figure 2 As shown, the inner wall of the elastic ring 15 abuts against the outer side of the oil inlet pipe 2, and the elastic ring 15 is located above the scraper ring 10.

[0057] like Figure 3As shown, a pair of reinforcing grooves 16 are provided on the top of the drill bit 1, and a reinforcing block 17 is fixedly connected to the bottom of the telescopic cover 4 and slidably connected to the reinforcing grooves 16. When the telescopic cover 4 moves, it will drive the reinforcing block 17 to move within the reinforcing grooves 16. The reinforcing block 17 can improve the stability of the telescopic cover 4 when it moves above the drill bit 1.

[0058] In other embodiments, the telescopic cover 4 can be designed as a complete cylindrical structure so that it does not expand radially. During drilling, the telescopic cover 4 moves axially and covers the filter hole 3. After drilling is completed, the telescopic cover 4 can be moved upward to expose the filter hole 3, which can also serve to scrape the filter hole 3.

[0059] Example 2: Figure 5-6 As shown in the comparative embodiment one, another embodiment of the present invention is as follows: the inner wall of the scraper ring 10 is provided with a plurality of connecting grooves 28 and roller grooves 30. A magnetic block 18 is fixedly connected to the inner side wall of the connecting groove 28. A discharge groove 29 is provided on the inner bottom wall of the connecting groove 28. A roller 19 is rotatably connected inside the roller groove 30. A plurality of sliding grooves 20 are provided on the roller 19. A metal block 21 is slidably connected inside the sliding groove 20. A second spring 22 is fixedly connected to the side of the metal block 21. A push-pull rod 23 and a second push-pull rod 24 are movably inserted inside the roller 19. An adjustment groove 25 is provided on the push-pull rod 23. The second push-pull rod 24 is movably inserted inside the adjustment groove 25. A pair of metal blocks 21 in the vertical direction are fixedly connected to the second push-pull rod 24. A pair of metal blocks 21 in the horizontal direction are fixedly connected to the push-pull rod 23.

[0060] When the scraper ring 10 moves on the oil inlet pipe 2, the friction between the roller 19 and the oil inlet pipe 2 will cause the roller 19 to rotate in the connecting groove 28. When the roller 19 rotates, it will drive all the mechanisms inside it to rotate together.

[0061] When the metal block 21 rotates to a position horizontally opposite to the magnetic block 18, the magnetic attraction of the magnetic block 18 on the metal block 21 will pull the push-pull rod 23 or the push-pull rod 24 to move closer to it. This will cause the push-pull rod 23 or the push-pull rod 24 to move the metal block 21 at the other end together. At this time, since the slide groove 20 is horizontally opposite to the magnetic block 18 and is far away from the magnetic block 18, it will be directly opposite the filter hole 3. Therefore, when the metal block 21 moves in the slide groove 20 and approaches the magnetic block 18, a negative pressure will be generated in the slide groove 20 on the side close to the oil inlet pipe 2. Under the action of the negative pressure, the mud and gravel in the filter hole 3 can be sucked up and put into the slide groove 20. This will prevent the phenomenon of mud and gravel entering the filter hole 3, which would reduce the speed of oil and gas entering the oil inlet pipe 2 and block the filter hole 3.

[0062] After the mud and gravel are sucked into the chute 20, when the chute 20 rotates downward to directly below the roller 19, or rotates upward to directly above the roller 19, the inner wall of the chute 30 will block the mud and gravel, making it difficult for them to move out of the chute 20. When the chute 20 rotates to a position directly opposite the magnetic block 18, under the magnetic attraction of the magnetic block 18, the metal block 21 will push the mud and gravel together toward the magnetic block 18. Then the mud and debris will fall into the discharge chute 29, and then pass through the discharge chute 29 and be discharged from the scraper ring 10, thus facilitating the cleaning of the mud and gravel sucked into the chute 20.

[0063] like Figure 5-6 As shown, the end of the second spring 22 away from the metal block 21 is fixedly connected to the inner wall of the slide groove 20 to improve the stability of the second spring 22 when it moves. The roller 19 has a push-pull groove 26 and a push-pull groove 27 that are movably inserted into the push-pull rod 23 and the second push-pull rod 24. A pair of slide grooves 20 in the horizontal direction communicate with the push-pull groove 26, and a pair of slide grooves 20 in the vertical direction communicate with the push-pull groove 27.

[0064] like Figure 10 As shown, a drilling and completion operation method of the present invention, which uses the above-mentioned integrated drilling and completion tool, includes the following steps:

[0065] S1: After drilling is completed, the telescopic cover 4 is brought into contact with the hole wall, and the oil and gas will enter the oil inlet pipe 2 through the filter hole 3.

[0066] S2: Activate the electric push rod 5 to move the scraper ring 10 on the oil inlet pipe 2 to scrape off the dirt and foreign matter adhering to it;

[0067] S3: When the scraper ring 10 moves upward, the magnetic block 18 will attract the metal block 21, creating a negative pressure in the chute 20 to clear the filter hole 3.

Figure 1 Based on the perspective of the observer, the side of the device facing the observer is defined as the front, the left side of the observer is defined as the left, and so on.
