METHOD OF BUILDING UNDERGROUND GAS STORAGES IN LOW AMPLITUDE WATER BEARING STRUCTURES OR WATER ENCROACHED GAS BEARING BEDS

摘要

FIELD: gas industry. SUBSTANCE: in proposed method injection wells uncovered by perforation below design level of gas-water contact surface should be arranged according to circular or segment scheme. In process of gas injecting, water bank formed around injection well is displaced by bed water to edge portions of storage where thickness of gas saturated formation is less than height of water bank. The latter will prevent spreading of gas over top of bed-reservoir. EFFECT: prevention of gas spreading over top of bed-reservoir. 1 dwg
