FIELD: maintenance of underground reservoirs made in coal salt, applicable in gas, oil, petroleum refining and other branches of industry. ^ SUBSTANCE: the method consists in cleaning, cooling and injection of trunk gas into the underground reservoirs of the gas storage by means of ejection of low-pressure gas, subsequent separation and drying of gas in the process of its extraction from the underground reservoirs. According to the invention, ejection of low-pressure gas at injection and extraction of gas from the gas storage is conducted by an active blow of compressed gas extracted from the earlier filled underground reservoirs of the gas storage with a maintenance of a stable pressure of the mentioned flow by a stepped control. ^ EFFECT: enhanced efficiency of maintenance of the gas storages. ^ 3 cl, 1 dwg |
