TECHNICAL FIELD

[0001] The utility model belongs to the technical field of downhole pipeline, specifically relates to a downhole pipeline temporary fixing structure convenient to dismount. BACKGROUND

[0002] The downhole pipeline temporary fixing structure refers to a temporary fixing device or method used in the downhole environment to ensure the stability and safety of the pipeline system. This fixing structure is crucial for downhole operation because it can prevent the pipeline from displacement or damage due to external forces (such as wind flow, water flow, rock movement, etc.), thereby ensuring the normal operation of downhole operation and the safety of workers.

[0003] The clamp is a ring-shaped device that can tightly wrap the pipeline and be fixed on the support or well wall through fasteners (such as bolts, nuts). The selection of fasteners should be based on the material, size, and working environment of the pipeline to ensure the reliability and durability of the fixing. The clamp is widely used as the main means of temporary fixing of downhole pipeline in the market. However, the traditional clamp fixing method often relies on a single bolt locking mechanism. This mechanism requires the clamp to tightly wrap the downhole pipeline, and then connects it with the wall or other fixing structure through the bolt. Although this method can achieve stable fixing of the pipeline to some extent, it exposes many inconveniences in the assembly process and subsequent maintenance and adjustment.

[0004] Specifically, the traditional bolt locking method often requires complex operation steps and high technical proficiency, which not only increases the installation time but also may result in poor fixing effect due to improper operation. In addition, in the special environment of downhole, it is more difficult to tighten or loosen the bolt due to factors such as narrow space and insufficient light. Once the pipeline needs to be repaired or replaced, the inconvenience of this fixing will be particularly prominent, which may seriously affect the efficiency and safety of downhole operation.
