Abstract

The present invention provides a salt cavern gas storage device, the salt cavern gas storage device communicates with an aboveground gas source, and includes a gas storage chamber, a brine chamber and a brine pool; the gas storage chamber and the brine chamber are salt caverns, and the The brine pool is set on the ground; the air storage chamber communicates with the ground air source through an air storage pipe; the brine chamber communicates with the brine pool through a brine pipe; the bottom of the air storage chamber communicates with the The bottom of the brine chamber is connected, and the air storage chamber, the brine chamber and the brine pool are all filled with brine. The invention provides a salt cavern gas storage device. When the gas storage chamber is deflated, the high-pressure gas is discharged from the gas storage chamber through the gas storage pipe, and the brine in the brine pool and the brine chamber enters the gas storage chamber through the connecting pipe, so that the gas in the gas storage chamber The remaining gas is discharged from the gas storage chamber to improve the volumetric efficiency of the salt chamber; at the same time, the brine provides support pressure to the gas storage chamber to avoid geological problems causing adverse effects on the ground. It has the advantages of high safety, simple structure, and easy preparation and application. .

Description

technical field [0001] The invention relates to the technical field of high-pressure gas storage, in particular to a salt cavern gas storage device. Background technique [0002] Salt caverns are underground caves formed in underground salt beds or salt domes after salt mines are mined by water-soluble mining methods, which can be used to store natural gas or oil. Generally, two pipe strings are required, one for injecting water and the other for returning brine, and the injected water is used to dissolve the salt layer to form a salt chamber. The geometric diameter of a single chamber is generally 60-90m, the height is 100-350m, and the storage capacity is 20-100m million m 3 . After mining, the salt cavity needs to be backfilled with saturated brine to ensure the stability of the geological structure; under the premise of ensuring geological safety, using the salt cavity for gas storage can also exert its economic value. [0003] At present, there are a large number of ...
