DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, purposes and effects realized by the application easy to understand, the application will be further described below in conjunction with specific embodiments.

[0023] Embodiment one: as shown in Figures 1-2 As shown in Figure 3 and Figure 8 The drilling and completion integrated tool described in the embodiments of the application comprises a drill bit 1, the top of the drill bit 1 is fixedly connected with an oil inlet pipe 2, and the oil inlet pipe 2 is provided with filter holes 3; A pair of telescopic covers 4 are arranged on the outer side of the oil inlet pipe 2, and a pair of symmetrically distributed electric push rods one 5 are fixedly connected to the surface of the oil inlet pipe 2, and the telescopic ends of the electric push rods one 5 are fixedly connected with the telescopic covers 4; The inner wall of the telescopic cover 4 is provided with a vertical slot 6, the inner top wall of the vertical slot 6 is fixedly connected with an electric push rod two 7, and the telescopic end of the electric push rod two 7 is fixedly connected with a mounting block 8; 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. 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.

[0024] 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. 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; 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. 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. 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.

[0025] like Figure 7 and Figure 9 As 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. 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.

[0026] like Figure 7 andFigure 9 As shown in the figure, the plug-in rod 11 is inserted in the plug-in groove 12 and the spring 9, the bottom of the scraping ring 10 abuts against the top of the drill bit 1, so as to improve the stability of the scraping ring 10, and the scraping ring 10 is not easy to rotate on the plug-in rod 11 when moving.

[0027] As shown in the figure, Figure 7 As shown in the figure, Figure 9 As shown in the figure, the surface of the plug-in rod 11 is in contact with the inner wall of the spring 9, the inner diameter of the spring 9 is greater than the diameter of the plug-in groove 12, so as to facilitate the scraping ring 10 to extrude the spring 9, and the spring 9 is contracted between the mounting block 8 and the scraping ring 10.

[0028] As shown in the figure, Figure 4 As shown in the figure, the surface of the oil inlet pipe 2 is fixedly connected with a sleeve ring 13, the outer side of the sleeve ring 13 is fixedly connected with a pair of connecting rods 14, the bottom of the pair of connecting rods 14 is fixedly connected with the same elastic ring 15; The outer side of the scraping ring 10 is trapezoidal, and the inner ring of the elastic ring 15 is a conical surface structure (combined with Figure 4 As shown in the figure, Figure 5 As shown in the figure), so that under the thrust of the scraping ring 10, the elastic ring 15 is more likely to be elastically deformed and expanded, thereby facilitating the scraping ring 10 to move up and down through the elastic ring 15; When the scraping ring 10 pushes the mud and gravel attached to the outer side of the oil inlet pipe 2 upward, the top of the scraping ring 10 will push the elastic ring 15 to produce elastic deformation and expansion, and when it expands, the bottom slope will rub with the top of the scraping ring 10, thereby scraping off the mud and gravel accumulated on the top of the scraping ring 10, and then the mud and debris can be quickly separated from the scraping ring 10 and fall down.

[0029] As shown in the figure, Figure 2 As shown in the figure, 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 scraping ring 10.

[0030] As shown in the figure, Figure 3 As shown in the figure, the top of the drill bit 1 is provided with a pair of reinforcing grooves 16, and the bottom of the telescopic cover 4 is fixedly connected with a reinforcing block 17 which is in sliding connection with the reinforcing grooves 16, when the telescopic cover 4 moves, the reinforcing block 17 will be driven to move in the reinforcing grooves 16, and the reinforcing block 17 can improve the stability of the telescopic cover 4 when moving above the drill bit 1.

[0031] In other embodiments, the telescopic cover 4 can be designed as a complete cylindrical structure, so that it will not expand radially, and the telescopic cover 4 moves axially and covers the filter hole 3 when drilling; after drilling is completed, the telescopic cover 4 can be moved upward to expose the filter hole 3, which can also play a role in scraping the filter hole 3.

[0032] Embodiment two: as shown in the figure, Figures 5-6As shown, the comparative example one, wherein another embodiment of the present application is: the inner wall of the scraping ring 10 is provided with a plurality of connecting grooves 28 and rolling grooves 30, the inner side wall of the connecting groove 28 is fixedly connected with the magnetic block 18, the inner bottom wall of the connecting groove 28 is provided with a discharge groove 29, the inside of the rolling groove 30 is rotatably connected with the roller 19, the roller 19 is provided with a plurality of sliding grooves 20, the inside of the sliding groove 20 is slidably connected with the metal block 21, the side of the metal block 21 is fixedly connected with the spring two 22, the inside of the roller 19 is movably inserted with the push-pull rod one 23 and the push-pull rod two 24, the push-pull rod one 23 is provided with an adjusting groove 25, the push-pull rod two 24 is movably inserted in the inside of the adjusting groove 25, a pair of the metal block 21 and the push-pull rod two 24 are fixedly connected in the vertical direction, a pair of the metal block 21 and the push-pull rod one 23 are fixedly connected in the horizontal direction.

[0033] When the scraping ring 10 moves on the oil inlet pipe 2, under the action of friction between the roller 19 and the oil inlet pipe 2, the roller 19 will rotate in the connecting groove 28, when the roller 19 rotates, it will drive all the mechanisms in it to rotate; When the metal block 21 rotates to the position horizontally opposite to the magnetic block 18, under the magnetic attraction of the magnetic block 18 to the metal block 21, the push-pull rod one 23 or the push-pull rod two 24 will be pulled to move towards the side close to it, thereby making the push-pull rod one 23 or the push-pull rod two 24 move the metal block 21 at the other end together, at this time, since the sliding groove 20 opposite to the magnetic block 18 and away from the magnetic block 18 will be directly opposite to the filter hole 3, when the metal block 21 moves in the sliding groove 20 and approaches the magnetic block 18, negative pressure will be generated in the sliding groove 20 close to the oil inlet pipe 2 side, under the action of negative pressure, the mud and gravel in the filter hole 3 can be sucked into the sliding groove 20, thereby the phenomenon that the speed of oil gas entering the oil inlet pipe 2 and the mud and gravel plugging the filter hole 3 are reduced due to the mud and gravel entering the filter hole 3 can be avoided; After the mud and gravel are sucked into the sliding groove 20, when the sliding groove 20 rotates to the position directly below or above the roller 19, the inner wall of the rolling groove 30 will block the mud and gravel, so that they are not easy to move out of the sliding groove 20, when the sliding groove 20 rotates to the position directly opposite to the magnetic block 18, under the magnetic attraction of the magnetic block 18, the metal block 21 will push the mud and gravel to move towards the magnetic block 18, then the mud and gravel will fall into the discharge groove 29, and then pass through the discharge groove 29 to be discharged from the scraping ring 10, so that the mud and gravel sucked in the sliding groove 20 can be conveniently cleaned.

[0034] As Figures 5-6As shown, the spring two 22 is fixedly connected with the inner side wall of the sliding groove 20 away from one end of the metal block 21, the stability of the spring two 22 is improved when moving, the inner part of the roller 19 is provided with a push-pull slot one 26 and a push-pull slot two 27, which are movably inserted with the push-pull rod one 23 and the push-pull rod two 24, a pair of the sliding grooves 20 in the horizontal direction are communicated with the push-pull slot one 26, and a pair of the sliding grooves 20 in the vertical direction are communicated with the push-pull slot two 27.
