Technical Field

[0001] This utility model relates to the field of oil extraction equipment technology, and in particular to a sand-proof screen pipe that is easy to install. Background Technology

[0002] Sand production is a common problem in oil well extraction. It can lead to a series of issues such as pump sticking, tubing wear, and formation pore blockage, severely impacting the well's production efficiency and lifespan. To address sand production, sand screens are typically installed in the well. These screens prevent formation sand from entering the wellbore while allowing crude oil to pass through smoothly, thus achieving sand control.

[0003] Currently, existing sand control screens present many inconveniences during installation. On the one hand, traditional sand control screens are mostly spliced ​​in multiple sections using flange or welding connections. Flange connections require a large number of bolts and nuts for fixing, and each bolt needs to be tightened one by one during installation, which is cumbersome and consumes a lot of time and manpower. Welded connections require professional welding equipment and operators, and cannot be disassembled after welding, making subsequent maintenance and replacement difficult.

[0004] Therefore, in view of the above situation, there is an urgent need to develop a sand-proof screen pipe that is easy to install in order to overcome the shortcomings in current practical applications. Utility Model Content

[0005] The purpose of this utility model embodiment is to provide a sand-proof screen pipe that is easy to install, in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An easy-to-install sand-control screen pipe includes a sand-control screen pipe with a lower connecting ring fixedly connected to its upper end and an upper connecting ring fixedly connected to its lower end. Adjacent sand-control screen pipes are connected via the upper and lower connecting rings. Multiple evenly distributed mating blocks are fixedly connected to the bottom end of the upper connecting ring. Each mating block has a slot on its outer wall. The upper outer wall of the lower connecting ring has a receiving groove, and the inner wall of the receiving groove has an embedding groove. The inner wall of the receiving groove also has multiple mating grooves, each corresponding to a mating block. Correspondingly, the mating block is inserted into the inner wall of the corresponding mating groove. The inner wall of the receiving groove is rotatably connected to a first connecting plate. A second connecting plate is fixedly connected to the first connecting plate, and the second connecting plate is attached to the inner side wall of the receiving groove. A plurality of evenly distributed clamping plates are fixedly connected to the inner wall of the second connecting plate, and the clamping plates correspond one-to-one with the embedding grooves. The clamping plates are slidably connected to the inner wall of the embedding grooves. When it is necessary to connect the upper connecting ring and the lower connecting ring, the clamping plate is inserted into the inner wall of the clamping groove. A locking element is also provided between the first connecting plate and the bottom end of the receiving groove.

[0008] In a further technical solution, the outer wall of the mating block is chamfered, and the inner wall of the slot is also chamfered.

[0009] In a further technical solution, a sealing plate is fixedly connected to the inner wall of the bottom end of the upper connecting ring, and a sealing groove is opened on the inner wall of the top end of the lower connecting ring, with the lower connecting ring fitting against the inner wall of the sealing groove.

[0010] In a further technical solution, the lower connecting ring sidewall is provided with an opening groove, and the opening groove is connected to the mating hole corresponding to the locking member.

[0011] In a further technical solution, the arc length of the card plate is greater than the arc length of the card slot.

[0012] In summary, the embodiments of this utility model have the following beneficial effects compared with the prior art:

[0013] 1. Two adjacent sand screens are connected by an upper connecting ring and a lower connecting ring. The mating block at the lower end of the upper connecting ring is inserted into the mating groove on the lower connecting ring. Then, by rotating the first connecting plate, the second connecting plate is moved. After that, the second connecting plate moves the clamping plate along the inner wall of the embedded groove. The clamping plate slides into the clamping groove, thereby restricting the movement of the mating block. When it is necessary to disassemble the adjacent sand screen, remove the locking part and rotate the first connecting plate in the opposite direction. The second connecting plate will then move the clamping plate away from the inner wall of the clamping groove. The installation and disassembly process is simple and quick.

[0014] 2. The first connecting plate is locked by the locking device, thereby controlling the plate to be stationary by the second connecting plate, which effectively restricts the mating block in the mating groove, thereby further improving the stability of the connection between the upper and lower connecting rings.

[0024] like Figures 1-5 As shown, this utility model embodiment provides an easy-to-install sand-proof screen pipe 1, including a sand-proof screen pipe 1. A lower connecting ring 3 is fixedly connected to the upper end of the sand-proof screen pipe 1, and an upper connecting ring 2 is fixedly connected to the lower end of the sand-proof screen pipe 1. Two adjacent sand-proof screen pipes 1 are connected by the upper connecting ring 2 and the lower connecting ring 3. Multiple evenly distributed mating blocks 6 are fixedly connected to the bottom end of the upper connecting ring 2. Each mating block 6 has a slot 7 on its outer wall. The upper outer wall of the lower connecting ring 3 has a receiving groove 10. The inner side wall of the receiving groove 10 has an embedding groove 9. The inner side wall of the receiving groove 10 also has multiple mating grooves 8, and each mating groove 8 corresponds one-to-one with a mating block 6. 6. The inner wall of the corresponding mating groove 8 is inserted into the receiving groove 10. The inner wall of the receiving groove 10 is rotatably connected to the first connecting plate 11. The second connecting plate 12 is fixedly connected to the first connecting plate 11 and fits against the inner side wall of the receiving groove 10. The inner wall of the second connecting plate 12 is fixedly connected to a plurality of evenly distributed clamping plates 13. The clamping plates 13 correspond one-to-one with the embedding groove 9. The clamping plates 13 are slidably connected to the inner wall of the embedding groove 9. When it is necessary to connect the upper connecting ring 2 and the lower connecting ring 3, the clamping plate 13 is inserted into the inner wall of the clamping groove 7. A locking member 14 is also provided between the first connecting plate 11 and the bottom of the receiving groove 10 to restrict the movement of the first connecting plate 11.

[0025] Furthermore, the outer wall of the mating block 6 is chamfered to facilitate insertion into the mating groove 8, and the inner wall of the slot 7 is also chamfered to facilitate insertion of the card plate 13 into the slot 7.

[0026] Furthermore, a sealing plate 5 is fixedly connected to the inner wall of the bottom end of the upper connecting ring 2, and a sealing groove 4 is opened on the inner wall of the top end of the lower connecting ring 3. The lower connecting ring 3 fits into the inner wall of the sealing groove 4, thereby improving the sealing effect between the upper connecting ring 2 and the lower connecting ring 3.

[0027] Furthermore, the lower connecting ring 3 has an opening groove 15 on its side wall, and the opening groove 15 is connected to the mating hole corresponding to the locking member 14, so as to facilitate cleaning the debris in the mating hole and avoid blockage.

[0028] Furthermore, the arc length of the card plate 13 is greater than the arc length of the slot 7, thereby ensuring that when the card plate 13 is inserted into the slot 7, the card plate 13 does not detach from the inner wall of the embedding groove 9, thereby applying a vertical locking force to the card plate 13 through the embedding groove 9, thereby restricting the movement of the card plate 13 in the vertical direction and effectively improving the stability of the mating block 6.

[0029] In this embodiment of the invention, two adjacent sand-proof screen pipes 1 are connected by an upper connecting ring 2 and a lower connecting ring 3. The mating block 6 at the lower end of the upper connecting ring 2 is inserted into the mating groove 8 on the lower connecting ring 3. Then, by rotating the first connecting plate 11, the second connecting plate 12 is moved. After that, the second connecting plate 12 drives the locking plate 13 to slide along the inner wall of the embedded groove 9. The locking plate 13 slides into the locking groove 7, thereby restricting the movement of the mating block 6. When it is necessary to disassemble the adjacent sand-proof screen pipe 1, the locking member 14 is removed, and the first connecting plate 11 is rotated in the opposite direction. Thus, the second connecting plate 12 drives the locking plate 13 to disengage from the inner wall of the locking groove 7. The installation and disassembly process is simple and quick. The locking member 14 locks the first connecting plate 11, thereby controlling the locking plate 13 to be stationary through the second connecting plate 12. This effectively restricts the mating block 6 securely in the mating groove 8, thereby further improving the stability of the connection between the upper connecting ring 2 and the lower connecting ring 3.
