Abstract

The invention relates to an underground gas storage which comprises a gas storage body, a first drainage pipe and a plurality of second drainage pipes, the gas storage body comprises a supporting layer and a sealing layer arranged in the supporting layer, and the second drainage pipes and at least part of the first drainage pipe are arranged between the supporting layer and the sealing layer. The second drainage pipes are annularly arranged and arranged on the gas storage body in a sleeving mode, the multiple second drainage pipes are arranged at intervals in the length direction of the gas storage body, the first drainage pipe is located at the bottom of the gas storage body, and all the second drainage pipes communicate with the first drainage pipe; a water inlet hole is formed in the second drainage pipe, and a drainage opening is formed in the end, away from the gas storage body, of the first drainage pipe. According to the underground gas storage, the problems that an existing gas storage cavern drainage system is tedious in operation process and high in operation cost are solved.
