FIELD: oil and gas industry.
SUBSTANCE: operating method of underground gas storages involves intermittent injection of gas by compressors, which is supplied from a main gas line through production and injection wells of an underground gas storage to a reservoir bed under pressure exceeding formation pressure; further extraction of gas from the underground storage for further gas supply to the main gas line. The above extraction from the underground storage and its supply to the main gas line is performed in a compressor mode that is performed till pressure in the reservoir bed reaches the value excluding allowable well water flooding. With that, a suction gas line of compressor is connected to a gas extraction pipeline from the underground gas storage, and a discharge gas line of compressors is connected to the main gas line.
EFFECT: improving operating efficiency of an underground gas storage.
