Problems solved by technology
[0006] The present invention is a method for storing natural gas based on the goaf of anhydrite mine. By using the roadway of the mined-out anhydrite mine after being mined to form an airtight warehouse after being blocked, the natural gas is stored in the warehouse under pressure. When natural gas is needed, the natural gas stored in the warehouse is exported, which solves the problems of high cost and high maintenance cost of the existing ground natural gas storage

Abstract
The invention discloses a method for storing natural gas based on hard gypsum mine goafs. The method comprises the steps of removing mining equipment, carrying out surface treatment on the hard gypsum mine goafs, blocking roadways, installing natural gas equipment and storing the natural gas. By fully utilizing the application of the hard gypsum mine goafs to the energy storage field and the material storage field and the mode of storing the energy or mateiral through gypsum mines, the method has the advantages that the land is saved, the investment is reduced, the fixed number of staff for operation is small, the safety is high, the environmental-friendliness is high, pollution is reduced, and the service life is long. The roadways of the exploited hard gypsum mine goafs are blocked for forming sealed chambers, and the natural gas is stored inside the chambers in a pressurized mode and can be output when to be used.
Description
technical field [0001] The invention belongs to the technical field of natural gas geological storage, in particular to a method for storing natural gas based on an anhydrite mine goaf. Background technique [0002] The consumption of natural gas is superimposed by the use of a large number of gas users, which has the imbalance of hours, days, months and seasons, and the gas supply volume of the gas source cannot be supplied synchronously with the unbalanced parts of the gas consumption. Gas storage is an effective method to solve the contradiction between the balance of gas supply and the imbalance of gas consumption, that is, it is necessary to establish a corresponding number of gas storage facilities. When the gas consumption is at a low peak, store the excess gas, and when the gas consumption is at a peak. [0003] At present, there are mainly two storage methods of natural gas: gaseous storage and liquid storage. The former includes ground storage tank storage, pipeli...
