FIELD: development of oil deposits with oil reserves difficult-to-recover. SUBSTANCE: in the method of simultaneous-separated injection of water and working agent, the latter is injected in form of stable gas-water foam. The foam is preliminarily produced at wellhead by ejection or bubbling when gas is supplied at low pressure, and water is supplied at high pressure. Foam is injected down to treated interval of perforation. Then, it is mixed with water by high pressure jet injector. produced mixture is injected into formation under the effect of elastic vibration for instance, with the aid of hydrodynamic generator. EFFECT: higher efficiency. 2 cl, 1 dwg
