The deepest salt cavern gas storage in China officially injects gas

　　Sinochem News Network News On June 8, Sinopec Natural Gas Branch's Jianghan Salt Cave Natural Gas Storage Well Wangchu 6 was officially put into production for gas injection, with a gas injection volume of 190,000 cubic meters on the first day
.
The well is more than 2,000 meters deep and is the deepest salt cavern underground gas storage in China
.
After the project is fully put into operation, the layout of Sinopec's gas storage will be further improved, which can effectively alleviate the contradiction between China's natural gas supply and demand, enhance the national natural gas strategic reserve, and ensure national energy security

Jianghan Salt Cave Gas Storage Injection and Production Station

　　Jianghan salt cavern natural gas storage is located in Qianjiang City, Hubei Province.
It is built using underground salt caverns.
Compared with the traditional gas storage built with depleted oil and gas reservoirs, the salt cavern gas storage has a large daily extraction capacity and a small amount of bottom gas.
The conversion between gas injection and gas extraction is flexible, and can be used for daily peak shaving and weekly peak shaving
.
The project was officially launched in 2019, with a total designed storage capacity of 4.
809 billion cubic meters, which will be implemented in "two phases and three phases"
.
The "Crown Prince 6" gas storage well put into production for gas injection this time is one of the four pilot wells in the first-stage project of the Jianghan Salt Cave Natural Gas Storage Project.
The first-stage project will be fully put into production in 2026
.

　　The target layer of the gas storage is more than 2,000 meters deep.
Sinopec Jianghan Oilfield has developed a set of construction technology series suitable for deep, multi-layered salt cavern gas storage, which provides guidance and reference for the construction of similar gas storages in China
.
Among them, the key point is to solve the problem of collapse of the extremely thick interlayer, so that the construction height of the gas storage is increased from 100 meters to 200 meters, and the gas storage capacity is greatly improved
.
In February of this year, the Hubei Provincial Consulting Project "Strategic Research on Efficient Construction of Multi-Interlayer Ultra-Deep and Super Large Salt Rock Gas Storage" undertaken by Jianghan Oilfield and Wuhan Institute of Geomechanics, Chinese Academy of Sciences passed the acceptance

Jianghan salt cavern gas storage completed natural gas replacement and ignited the venting torch

　　Sinopec Natural Gas Branch has strengthened on-site management, effectively carried out relevant work such as confirmation of gas sources and external environment, inspection of production conditions, and actively implemented various risk management and control measures to ensure the safety and stability of the gas injection process
.

　　In recent years, Sinopec has thoroughly implemented the strategic deployment of the construction of the national production, supply, storage and marketing system, and continued to accelerate the construction of gas storage capacity.
At present, several gas storage depots such as Jintan and Wen 96 have been built
.
Especially in 2021, with the completion of gas injection of Wei 11 gas storage in Sinopec Zhongyuan Oilfield, it marks the completion and operation of Zhongyuan gas storage group, the largest natural gas underground gas storage group in North China
.
The gas storage capacity of the Central Plains gas storage group has reached 10.
03 billion cubic meters, providing a strong resource guarantee for gas storage and peak regulation and stable gas supply in North China and the Yellow River Basin
.
During the "14th Five-Year Plan" period, Sinopec will successively build multiple gas storage depots in the Zhongyuan Oilfield to further enhance the peak-shaving capacity of gas storage and help the high-quality development of China's natural gas industry
