Description

Technical Field

[0001] This utility model belongs to the field of oil casing, specifically a quick-connect oil casing. Background Technology

[0002] Oil casing is a steel pipe used to support the well wall of oil and gas wells to ensure the normal operation of the entire well after drilling and completion. Each well requires several layers of casing depending on the drilling depth and geological conditions.

[0003] Most existing oil casings require couplings for splicing, which makes splicing inconvenient for operators and reduces the practicality of the equipment. Furthermore, most existing oil casings cannot reinforce or seal the joints between multiple sets of oil casings, which reduces both the strength and the sealing of the splices. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a quick-connect oil casing, which solves the problems in the prior art where couplings are still required to connect the casings during splicing, and where it is impossible to reinforce the splices between multiple sets of oil casings or to seal the splices.

[0005] A quick-connect oil casing includes an oil casing body, a splicing tube fixedly installed on one side of the oil casing body, a splicing sleeve fixedly installed on the side of the oil casing body away from the splicing tube, and a sealing and reinforcing component fixedly installed on the outer side of the oil casing body near the splicing tube, which can reinforce and seal the splice joint of the two sets of oil casings.

[0006] Preferably, the sealing and reinforcing component has a fixing slot on its inner side, and a sealing ring is provided at the middle position of the outer side and the inner side of the fixing slot. Multiple sets of internal threaded holes are evenly provided on the inner side of the fixing slot, and multiple sets of threaded rods are evenly inserted on the outer side of the sealing and reinforcing component, and the threaded rods are compatible with the internal threaded holes.

[0007] Preferably, a fixing tube is fixedly sleeved on the side of the splicing thread groove away from the oil casing body. The fixing tube has multiple sets of fixing holes inside. A sealing groove is provided on both the outer and inner sides of the fixing tube. The fixing holes are adapted to the threaded rod, and the sealing groove is adapted to the sealing ring.

[0008] Preferably, the sealing and reinforcing component has multiple sets of insertion holes evenly distributed inside, and the insertion holes are adapted to the threaded rod. A handle is fixedly installed at the end of the threaded rod away from the sealing and reinforcing component.

[0009] Preferably, the outer side of the splicing tube is provided with splicing thread teeth, and the inner side of the splicing tube is provided with splicing thread groove, and the splicing thread groove and the splicing thread teeth are adapted to each other.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] 1. This utility model involves picking up two sets of oil casing bodies, aligning the splicing insert with the splicing casing, and then reversing the two sets of oil casing bodies. During the reversal, the splicing thread teeth are turned into the splicing thread groove, allowing for rapid splicing of multiple sets of oil casings. This makes splicing easier for operators and improves the practicality of the device.

[0012] 2. This utility model involves inserting a fixed tube into a fixed slot, which then drives a sealing ring into a sealing groove. The sealing groove and sealing ring work together to seal the joint between two sets of oil casing bodies. A threaded rod is then inserted into a fixed hole. After insertion, the threaded rod is rotated to the inside of the internal threaded hole, securing the fixed tube to the fixed slot. This allows operators to reinforce and seal the joints between multiple sets of oil casing bodies, improving both the strength and sealing of the joints. Attached Figure Description

[0017] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0018] like Figures 1 to 3 As shown:

[0019] Example 1: This utility model provides a quick-connect oil casing, including an oil casing body 1, a splicing tube 11 fixedly installed on one side of the oil casing body 1, a splicing sleeve 13 fixedly installed on the side of the oil casing body 1 away from the splicing tube 11, and a sealing and reinforcing component 2 fixedly installed on the outer side of the oil casing body 1 near the splicing tube 11, which can reinforce and seal the splice of the two sets of oil casings.

[0020] Preferably, the outer side of the splicing tube 11 is provided with splicing thread teeth 10, and the inner side of the splicing sleeve 13 is provided with splicing thread groove 12. The splicing thread groove 12 and the splicing thread teeth 10 are mutually compatible. Multiple sets of oil casing can be spliced ​​by utilizing the mutual cooperation of the splicing thread teeth 10 and the splicing thread groove 12.

[0021] As can be seen from the above, when using the equipment, first pick up the two sets of oil casing bodies 1, then align the splicing pipe 11 and the splicing casing 13 with each other, and then reverse the two sets of oil casing bodies 1. When reversing, rotate the splicing thread teeth 10 into the splicing thread groove 12. After rotating, quickly splice multiple sets of oil casings, which makes it more convenient for operators to splice and improves the practicality of the equipment.

[0022] Example 2: This example is basically the same as the previous example, except that a fixing slot 25 is provided on the inner side of the sealing and reinforcing component 2. A sealing ring 24 is provided at the middle position of the outer side and the inner side of the fixing slot 25. Multiple sets of internal threaded holes 26 are evenly provided on the inner side of the fixing slot 25. Multiple sets of threaded rods 23 are evenly inserted on the outer side of the sealing and reinforcing component 2, and the threaded rods 23 and the internal threaded holes 26 are mutually compatible.

[0023] Preferably, a fixing tube 20 is fixedly sleeved on the side of the splicing thread groove 12 away from the oil casing body 1. The fixing tube 20 has multiple sets of fixing holes 22 inside. A sealing groove 21 is provided on both the outer and inner sides of the fixing tube 20. The fixing holes 22 are adapted to the threaded rod 23, and the sealing groove 21 is adapted to the sealing ring 24.

[0024] Preferably, the sealing and reinforcing component 2 has multiple sets of insertion holes evenly distributed inside, and the insertion holes are compatible with the threaded rod 23. A handle is fixedly installed at the end of the threaded rod 23 away from the sealing and reinforcing component 2. The insertion holes make it easy for the operator to install the threaded rod 23, and the handle makes it easy for the operator to rotate the threaded rod 23.

[0025] As can be seen from the above, after the oil casing body 1 is spliced, the fixed insertion tube 20 is inserted into the fixed slot 25. After insertion, the sealing ring 24 is driven into the sealing groove 21. After being driven into the sealing groove 21, the joint of the two oil casing bodies 1 can be sealed by the cooperation of the sealing groove 21 and the sealing ring 24. Then, the threaded rod 23 is inserted into the fixed hole 22. After insertion, the threaded rod 23 is rotated to the internal threaded hole 26. After being rotated, the fixed insertion tube 20 is fixed into the fixed slot 25 by the threaded rod 23. This makes it easier for operators to reinforce the joint between multiple oil casing bodies 1 and seal the joint. This not only improves the firmness of the splicing between multiple oil casing bodies 1, but also improves the sealing performance of the joint between multiple oil casing bodies 1.

[0026] Working principle: In use, first lift the two sets of oil casing bodies 1. After lifting, align the splicing insert 11 with the splicing casing 13. After alignment, reverse the two sets of oil casing bodies 1. During reversal, the splicing thread teeth 10 are turned into the splicing thread groove 12. After turning, multiple sets of oil casing are quickly spliced, making splicing easier for operators and improving the practicality of the device. After the oil casing bodies 1 are spliced, the fixed insert 20 is inserted into the fixed slot 25. After insertion, the sealing ring 24 is engaged in the sealing groove 21. The joint between the sealing groove 21 and the sealing ring 24 can be sealed by the cooperation of the two sets of oil casing bodies 1. Then, the threaded rod 23 is inserted into the inside of the fixing hole 22. After insertion, the threaded rod 23 is rotated to the inside of the internal threaded hole 26. After rotation, the threaded rod 23 is used to fix the fixing tube 20 into the inside of the fixing slot 25. This makes it easy for operators to reinforce the joint between multiple sets of oil casing bodies 1 and seal the joint. This not only improves the firmness of the joint between multiple sets of oil casing bodies 1, but also improves the sealing performance of the joint between multiple sets of oil casing bodies 1.
