Zusammenfassung:	FIELD: oil-and-gas industry. ^ SUBSTANCE: water-gas mix (WGM) is prepared by fluid-gas disperser (FGD) arranged at injection well mouth whereto compressed water and gas are fed. Gas is bled from gas wells or from tapped gas-saturated interval isolated from injection interval and communicated via circular space behind lift tube string and shut-off valves and accessories with FGD. Note here that WGM is injected by alternating in each cycle either injection of gas only or injection of water and gas, or gas and water, on maintaining injection well bottom hole pressure in injection interval with the following conditions observed: Pg
