Embodiment Construction

[0013] In order to make the above and other objects, features and advantages of the present invention more comprehensible, preferred embodiments are listed below and described in detail in conjunction with the accompanying drawings.

[0014] refer to figure 1 with figure 2 , figure 1 It is a schematic diagram of the structure of the anti-collision device for the wellhead pipeline, figure 2 is along figure 1 A cross-sectional view along the A-A direction in . The wellhead cable anti-collision device of the present invention includes a body 1 , a screw 2 , a spring catch 3 , a handle 4 and a washer 5 . The spring stopper 3 is located on the upper end surface of the body 1, and is used to block the cable 6 in the groove on the upper end surface of the body 1, so as to prevent the cable 6 from being touched by the oil pipe. One end of the spring catch 3 is provided with a round hole, and the spring catch 3 is connected in the threaded hole of the body 1 by the washer 5 and ...

Abstract

The invention provides a well opening cable anti-collision device, which comprises a body and a spring baffle sheet, wherein the body consists of two identical semicircular tubes, two grooves are arranged on the inner side and the upper end surface of the semicircular tube of the body and are used for placing cables placed into a well, and the spring baffle sheet is positioned at the upper end surface of the body and is used for blocking the cables into the grooves arranged at the upper surface of the body. The well opening cable anti-collision device can prevent an oil pipe from colliding pipelines and cables in the well entering process, the structure is simple, the processing and the installation are easy, the operation is simple and convenient, the labor is saved, and the well openingcable anti-collision device is applicable to the well entering installation or the well exiting recovery of cables in different types.

Description

technical field [0001] The invention relates to wellhead construction equipment for oil, gas and water wells, in particular to a wellhead cable anti-collision device. Background technique [0002] With the intelligent development of oilfield development, the requirements for the development of oil, gas and water wells are getting higher and higher, especially fine and precise layered water injection, layered oil recovery and layered testing. In order to achieve these goals, various downhole tools such as hydraulic control pipelines, capillary tubes, optical fibers and cables are required to be lowered. When these pipelines and cables go downhole, the oil pipes often shake and collide with the pipelines, causing the pipelines to be deformed or even broken. For this reason we invented a new wellhead cable anti-collision device, which solves the above technical problems. Contents of the invention [0003] The object of the present invention is to provide a wellhead cable an...
