FIELD: oil-and-gas production.
SUBSTANCE: invention related to oil-and-gas production and can be used for construction and operation gas underground storages (GUS) on depleted oil and oil and gas reservoirs basis. Method includes pumping gas into storage and its withdrawal throughout wells. Further during gas into bottomhole, inject at least for one well GUS composition, consisting form oil soluble demulsifier and depressor, used in mass ration from 5:1 up to 1:5. Mentioned above composition injected in quantity from 0.02 to 0.2% mass, of reservoir fluid oil phase, extracted incidentally with gas.
EFFECT: increase depleted field porous volume use, increase of hydrocarbons production rate, lift coefficient of efficiency and GUS reliability increase.
