Description

Technical Field

[0001] This utility model belongs to the technical field of drilling and completion auxiliary devices, and in particular relates to a fixing device for a blowout pipeline used in drilling and completion. Background Technology

[0002] Well control in oil drilling is a crucial aspect of oil and gas exploration and development, serving as a prerequisite and guarantee for safe production. It is also known as well kick control or pressure control; these terms essentially refer to the same thing: controlling formation pressure through specific methods to maintain well pressure balance and ensure smooth operations. The primary method is using blowout lines to transport different fluid media from the well to the outside. However, during the transport of materials, unstable flow of the fluid media within the pipe, such as pressure pulsations, flow rate changes, and media displacement, can cause the blowout line to rise or oscillate, leading to wear at pipe connections. Prolonged use can result in pipe damage and leaks, compromising well control safety during oil drilling and completion operations. A search revealed that patent application number 202021591080.X discloses a fixing device for a blowout pipeline during drilling and completion, comprising a base plate and a pipeline. Both sides of the upper surface of the base plate are inserted with helical rods. A support base is fixedly connected to the upper surface of the base plate. A first compression spring is fixedly connected to the inner bottom wall of the support base. A support frame is fixedly connected to the top of the first compression spring. A first arc-shaped clamping plate is fixedly connected to the top of the support frame.

[0003] However, in actual use, the applicant found that the pipeline is fixed by the cooperation of the support base and the fixing block. The support base and the fixing block are connected and fixed by clamping bolts. Since there are multiple support bases and fixing blocks along the pipeline, multiple clamping bolts need to be disassembled and installed with external tools when maintaining the device, which is not convenient. In view of this, we propose a well completion blowout pipeline fixing device. Utility Model Content

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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-3 As shown, this utility model provides a technical solution:

[0021] A well completion blowout line fixing device includes a support base 1, a fixing block 2, and a pipe 7. The top of the support base 1 and the bottom of the fixing block 2 are both provided with arc-shaped grooves, and arc-shaped vibration damping pads 3 are fixedly installed on the inner walls of the arc-shaped grooves. Slots 12 are provided at the four corners of the top of the support base 1. A guide groove 11 is provided inside the support base 1, and the guide groove 11 communicates with the slots 12. Limiting beams 5 are symmetrically slidably connected in the support base 1 below the arc-shaped vibration damping pads 3. The limiting beams 5 slide along the guide grooves 11. A double-ended screw 6 is rotatably connected inside the support base 1 via bearings. The two ends of the double-ended screw 6 have opposite rotation directions, and each end of the double-ended screw 6 is threaded through one of the two limiting beams 5. In the middle, the front end of the double-headed screw 6 extends to the outside of the support base 1 and is fitted with an adjusting handle 61. Connecting rods 4 are fixedly installed at the four corners of the bottom of the fixing block 2, and the connecting rods 4 are connected to the slots 12. A slot 41 is provided on the lower side wall of the connecting rod 4, and the slot 41 is connected to the end of the limiting beam 5. Fixed supports 13 are symmetrically arranged on both sides of the lower part of the support base 1, and fixed holes 131 are symmetrically provided on the fixed supports 13. Limiting rings 71 are fixedly installed on the outer wall of the pipe 7, and several sets of limiting rings 71 are provided on the outer wall of the pipe 7. The support base 1 and the fixing block 2 are fitted onto the pipe 7 between a set of limiting rings 71. By placing the pipe 7... Place the arc-shaped vibration damping pad 3 on the support base 1 and position the support base 1 between a set of limiting retaining rings 71. Then, insert the connecting rod 4 at the bottom of the fixing block 2 into the slot 12 at the top of the support base 1. Finally, rotate the double-ended screw 6 clockwise to drive the two limiting beams 5 to move away synchronously, so that the ends of the limiting beams 5 are locked in the slots 41. This quickly fixes the fixing block 2 onto the support base 1 without the need for external tools, making the operation convenient. The limiting retaining rings 71 prevent slippage between the pipe 7 and the support base 1, and the arc-shaped vibration damping pad 3 dampens the vibration of the pipe 7, allowing for more stable transport. In use, the pipe 7 can be placed on top of the support base 1 first. Place the support base 1 on the arc-shaped vibration damping pad 3 and position it between a set of limiting retaining rings 71. Then, pass the screw through the fixing hole 131 to fix the support base 1 in a suitable position. Next, align the connecting rod 4 at the bottom of the fixing block 2 and insert it into the slot 12. Manually press the fixing block 2 down. Then, manually turn the adjusting handle 61 clockwise to drive the double-headed screw 6 to rotate. The rotation of the double-headed screw 6 can drive the two limiting beams 5 to move away synchronously along the guide slide 11 and make the ends of the limiting beams 5 snap into the slots 41. Lock the connecting rod 4 in the slot 12. The fixing block 2 can be quickly fixed on the top of the support base 1, and the pipe 7 can be fixed by the support base 1 and the fixing block 2.

[0022] The inner wall of the arc-shaped groove is provided with a T-shaped connecting groove 8. Both the support base 1 and the fixing block 2 have two T-shaped connecting grooves 8 on their inner walls. The arc-shaped vibration damping pad 3 is equipped with a T-shaped connecting slider 31, which engages with the T-shaped connecting groove 8. The two ends of the lower arc-shaped vibration damping pad 3 are flush with the top of the support base 1, and the two ends of the upper arc-shaped vibration damping pad 3 are flush with the bottom of the fixing block 2. The engagement of the T-shaped connecting slider 31 with the T-shaped connecting groove 8 facilitates easy replacement of aging arc-shaped vibration damping pads 3, resulting in better performance. When the arc-shaped vibration damping pad 3 needs to be replaced due to aging after a period of time, the fixing block 2 can be removed from the top of the support base 1, and the pipe 7 can be removed from the support base 1. Then, the arc-shaped vibration damping pad 3 in the arc groove of the support base 1 and the fixing block 2 can be manually removed. Next, the T-shaped connecting slider 31 on the new arc-shaped vibration damping pad 3 is aligned and slid into the T-shaped connecting groove 8, so that the two ends of the lower arc-shaped vibration damping pad 3 are flush with the top of the support base 1, and the two ends of the upper arc-shaped vibration damping pad 3 are flush with the bottom of the fixing block 2. This completes the quick replacement of the aging arc-shaped vibration damping pad 3.

[0023] Working principle: In use, first place the pipe 7 on the arc-shaped vibration damping pad 3 on top of the support base 1, and position the support base 1 between a set of limiting retaining rings 71. Then, pass the screw through the fixing hole 131 to fix the support base 1 in the appropriate position. Next, align the connecting rod 4 at the bottom of the fixing block 2 and insert it into the slot 12, and manually press the fixing block 2 downwards. Then, manually turn the adjusting handle 61 clockwise to drive the double-ended screw 6 to rotate. The rotation of the double-ended screw 6 can drive the two limiting beams 5 to move away synchronously along the guide groove 11, and make the ends of the limiting beams 5 engage in the slots 41, locking the connecting rod 4 in the slot 12. This will quickly fix the fixing block 2 in place. The top of the support base 1 allows the pipe 7 to be fixed by the support base 1 and the fixing block 2. When the arc-shaped vibration damping pad 3 needs to be replaced due to aging after a period of time, the fixing block 2 can be removed from the top of the support base 1 and the pipe 7 can be removed from the support base 1. The arc-shaped vibration damping pad 3 in the arc groove of the support base 1 and the fixing block 2 can then be manually removed. Next, the T-shaped connecting slider 31 on the new arc-shaped vibration damping pad 3 is aligned and slid into the T-shaped connecting groove 8, and the two ends of the lower arc-shaped vibration damping pad 3 are flush with the top of the support base 1, and the two ends of the upper arc-shaped vibration damping pad 3 are flush with the bottom of the fixing block 2. This allows for the quick replacement of the aged arc-shaped vibration damping pad 3.
