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

Embodiment 1

[0038] Such as Figure 1-2 , a high-pressure underground gas storage well fixing device, which includes:

[0039] The transverse rigid structure 8 is fixed on the carrier 9 next to the gas storage well (the carrier 9 is a concrete structure in this embodiment), and rigidly connects at least two adjacent gas storage wells, the The transverse rigid structure 8 is arranged in multiple layers from top to bottom along the gas storage well;

[0040] Vertical rigid structure, the vertical rigid structure is fixed on the carrier 9 beside the gas storage well and / or the horizontal rigid structure 8, the top of the vertical rigid structure can be detachably connected with the seal of the gas storage well head connection, the horizontal rigid frame 8 and the vertical rigid frame are both steel structures.

[0041] In this embodiment, the transverse rigid structure 8 includes a hoop 7 and a bracket (the bracket is a network structure formed by a number of steel bars fixedly connected, s...

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. The fixing device comprises a transverse rigid framework and a vertical rigid framework. The transverse rigid framework is fixed to carriers beside the gas storage wells and is in rigid connection with at least two adjacent gas storage wells. The vertical rigid framework is fixed to the carriers beside the gas storage wells and / or the transverse rigid framework. The top of the vertical rigid framework is detachably connected with seal heads of the gas storage wells. By the adoption of the fixing device for the high-pressure underground gas storage wells, the use safety of the gas storage wells is improved, and opening of well mouths of the gas storage wells is facilitated. The invention further discloses a whole structure and a fixing method of the corresponding gas storage wells.

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...
