FIELD: oil and gas industry.
SUBSTANCE: method for prevention of deposition eliminates formation thereof by maintaining concentrations of sodium chloride dissolved in formation water at a level excluding its crystallization. Maintenance of specified value of concentration provides injection of humidified gas into the underground storage to exclude the process of absorption by gas moisture from formation water. The required amount of fresh water to humidify the injected gas is defined as the difference in absolute maximum gas moisture content in the formation conditions and absolute moisture content of gas supplied from the main pipeline for injecting into the underground storage.
EFFECT: increased duration of wells and storages operation, and total volume of extracted gas, increased overhaul period, operation for liquidation of salt plugs is eliminated.
