The application discloses a method for determining the minimum buried depth of a compressed energy storage underground gas storage, comprising the following steps: setting basic parameters of the compressed energy storage underground gas storage according to geological data of rock and volume requirements of the gas storage; considering factors of gas storage pressure, rock gravity, shear strength of surrounding rock and broken surface of the surrounding rock under pressure, establishing a vertical mechanical equation of the gas storage by adopting a conical body model, and obtaining a vertical buried depth capable of meeting maximum gas storage pressure requirements; and establishing a horizontal mechanical equation of the gas storage according to the basic parameters and the vertical buried depth of the gas storage, and obtaining a horizontal buried depth capable of meeting the maximum gas storage pressure requirements. Whether the vertical buried depth of the gas storage meets the limit inflation pressure is determined first, and then the horizontal broken surface mechanical equation is substituted into the horizontal buried depth on the basis of the vertical buried depth, so as to determine whether the horizontal buried depth meets the limit inflation pressure. The calculation method is simple, fast, accurate, and has good economic applicability.
