Leaking stoppage construction process of sealing cap for oil plugging

Abstract

The invention relates to a leaking stoppage construction process of a sealing cap for oil plugging. The leaking stoppage construction process is characterized by comprising the following specific construction processes: S1, performing construction preparation; S2, performing leak detection and marking; S3, polishing and cleaning; S4, fixing a sealing cap; S5, performing long-acting leaking stoppage; S6, performing sealing; and S7, performing leak detection. A pressure relief column on the sealing cap structure is kept in a smooth state, the sealing cap structure covers the leakage position, then the end of the sealing cap is connected with the leakage position in a gluing mode, and at the moment, leaked liquid can be discharged from the position of the inner threaded hole of the pressure relief column. After the leaking stoppage glue is solidified, a sealing ring is nested in a plugging bolt to be matched with the pressure relief column to achieve leaking stoppage of the leaking position. Even in a leakage state, the leakage stoppage can be completed without power failure or shutdown. The pressure relief column is arranged on the sealing cap structure, the pressure relief column is opened during leaking stoppage, the pressure relief column is plugged after the plugging glue is solidified, and leaking stoppage under the pressure state can be achieved.

Description

technical field [0001] The invention relates to the field of plugging technology of sealing caps, in particular to a plugging construction technology of sealing caps for oil plugging. Background technique [0002] The bolt position of the flange connection of the general liquid conveying pipeline structure is prone to liquid leakage due to long-term use or the reduction of sealing performance, or the problem of trachoma on the pipeline leads to oil leakage; therefore, it is necessary to The common method of plugging these positions on the pipeline is to use plugging glue to wrap around the bolts or around the trachoma; however, the liquid in the pipeline is often transported under pressure, and the plugging glue applied to the trachoma and bolts is often not used. There will be a breakthrough before curing, and it is often necessary to release pressure and glue, which is very troublesome; therefore, a new sealing cap plugging construction process is needed to effectively plu...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a sealing cap plugging construction process for oil plugging, which can solve the problem that when the plugging glue for oil plugging is used to block trachoma and leakage bolts, it will be broken by the liquid under pressure before it solidifies. It is very troublesome to need pressure relief and plugging
