Fixing device for high-pressure underground gas storage wells and whole structure and fixing method of gas storage wells

Abstract

The invention relates to the field of high-pressure underground gas storage wells, in particular to a fixing device for high-pressure underground gas storage wells, which includes: a transverse rigid structure fixed on a carrier beside the gas storage well and rigidly connected to at least two The adjacent gas storage well; a vertical rigid structure, the vertical rigid structure is fixed on the carrier beside the gas storage well and / or the horizontal rigid structure, and the top of the vertical rigid structure is detachably connected to the The head connection of the gas storage well is described; the purpose of the invention is to provide a high-pressure underground gas storage well fixing device that increases the safety of the gas storage well and facilitates the opening of the wellhead of the gas storage well, and also discloses the corresponding overall structure and fixing method of the gas storage well.

Description

technical field [0001] The invention relates to the field of high-pressure underground gas storage wells, in particular to a fixing device for high-pressure underground gas storage wells. Background technique [0002] At present, with the vigorous promotion of natural gas energy construction in various places, the policy of reducing environmental pollution, and the construction of CNG peak-shaving stations such as CNG filling stations and factories, high-pressure underground gas storage wells are the first choice for many gas storage methods. [0003] After a period of use in high-pressure underground gas storage wells, there will be some potential safety hazards, such as the wellbore of the gas storage well going up, sinking, the wellbore bursting out of the ground, and the threaded joints of the wellhead head being fatigued and corroded, causing the head to fly away. Wellbore and ground. [0004] At the same time, due to the above safety reasons, a very cumbersome mechani...

Problems solved by technology

[0003] After a period of use in high-pressure underground gas storage wells, there will be some potential safety hazards, such as the wellbore of the gas storage well going up, sinking, the wellbore bursting out of the ground, and the threaded joints of the wellhead head being fatigued and corroded, causing the head to fly away. Wellbore and ground

[0004] At the same time, due to the above safety reasons, a very cumbersome mechanical fixing structure is currently used to fix the wellhead of the gas storage well. It is very laborious to open the wellhead to detect the high-pressure underground gas storage well. security risks
