摘要： A geological gas storage system and a method of detecting gas leakage from the geological gas storage system by using pressure monitoring, the geological gas storage system including: a formation structure including a reservoir formed of a permeable rock material in deep onshore/offshore formations, an impermeable cap rock layer formed above the reservoir, and an upper permeable formation formed of a permeable rock material above the cap rock layer; a hollow casing inserted in inner walls of the gas injection well bored from the ground to the reservoir and including a portion disposed at the same depth as a depth of the reservoir in which a plurality of gas injection holes are perforated in a circumferential direction of the casing; and a pressure sensor disposed at the same depth as a depth of the upper permeable formation and detecting pressure of the upper permeable formation. The method of detecting gas leakage from the geological gas storage system by using pressure monitoring includes detecting gas leakage from the reservoir by measuring a change in pressure of the upper permeable formation by using a pressure sensor installed at the upper permeable formation in the geological gas storage system having the above structure.
