Description

Technical Field

[0001] The utility model relates to the technical field of composite pipes, in particular to a temperature-resistant, high-pressure and shock-proof composite continuous pipe. Background Art

[0002] The commonly used rodless oil production method is to use conventional oil pipes as the oil outlet channel, lower the power equipment into the well, connect the lower end of the pipe string to the submersible pump, connect the upper end of the pipe string to the wellhead, connect the lower end of the submersible cable to the submersible pump motor, and tie the submersible cable to the outer wall of the oil pipe with cable clips and coupling joints, and use the submersible cable to provide power from the ground.

[0003] In the prior art, there is a rodless oil production intelligent composite continuous pipe with a publication number of CN110593779A, which includes a base pipe, multiple cables and multiple optical cables. The outer wall of the base pipe is wrapped with an anti-corrosion sealing layer, and the outer wall of the anti-corrosion sealing layer is wrapped with multiple layers of reinforcement layers. Multiple cables and multiple optical cables are fixedly embedded in the outer wall of the reinforcement layer, and the multiple cables and multiple optical cables are symmetrically distributed. One end of the multiple cables and multiple optical cables extends to the outside of the base pipe. The outer wall of the reinforcement layer is also fixedly embedded with multiple tensile fibers, and the multiple tensile fibers are evenly distributed on the outer wall of the reinforcement layer. The outer wall of the reinforcement layer is wrapped with a protective layer, and the outer wall of the protective layer is fixedly sleeved with a connector shell. The rodless oil production intelligent composite continuous pipe integrates the cables and optical cables in the pipe body, thereby improving the protection effect of the cables and optical cables, and is convenient for people to use. At the same time, it improves the firmness between the pipe body and the connector, which is convenient for people to use.

[0004] In the above technical solution, when the pipeline is transporting materials, the internal pressure is relatively high and the movement of the materials inside will cause the pipe wall to fluctuate, thereby causing the pipeline to vibrate. If the pipeline is in a vibrating state for a long time, the fixing bracket of the pipeline will loosen and fall off. For this reason, we have proposed a temperature-resistant, high-pressure and shock-proof composite continuous pipe. Utility Model Content

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0012] The utility model arranges a damping and shock-proofing tube between an outer tube and an inner tube, and the first and second shock-proofing layers of the damping and shock-proofing tube are alternately arranged between the first flexible belt layer, the second flexible belt layer and the third flexible belt layer.
