Description

Technical Field

[0001] The utility model relates to the technical field of well logging auxiliary tools, in particular to an eccentric wellhead adjustable bracket structure. Background Art

[0002] Due to certain special conditions, the eccentric wellhead needs to be removed from the casing and the detection cable needs to be passed through the test hole on the eccentric wellhead. After the detection cable has entered the well to a certain depth, the eccentric wellhead will be restored to the casing. During this period, the eccentric wellhead will be temporarily placed horizontally between the wellhead and the logging vehicle. When a fixed-height bracket is used, the height above the ground will change due to the different tension levels of the detection cable as the length of the cable enters the well, which will generate great friction between the detection cable and the test hole with a smaller diameter, damaging the sealing structure of the test hole, posing a safety hazard, and having a significant adverse effect on the cable life.

[0003] During operation, the fixation of the base is an important factor in ensuring the stability of the bracket. The stability of the base will affect the stability of the height or position of the bracket. If the base cannot be fixed, the bracket may be unstable and easy to tip over or move, which will lead to dangerous situations and may damage equipment or endanger the safety of workers. It may be necessary to stop work to solve the problem, which will cause project delays and increase costs. Utility Model Content
