FIELD: oil and gas production.
SUBSTANCE: procedure consists in separation of gas from oil and in pressurising it with water by means of fluid-gas ejector. Separated low pressure gas from the separator of the second stage of separation of a booster pump or from an installation of preliminary water drain is directed into a suction chamber of the fluid-gas ejector to combine a gas utilisation unit with a process circuit of 2-stage gas separation. As active medium part of drained commodity high pressure water is supplied into the suction chamber of the fluid-gas ejector. Water-gas mixture of fluid-gas ejector discharge is directed to an inlet of the separator of the first stage of separation.
EFFECT: combination of process of gas utilisation with process circuit of two-stage separation of gas from oil.
