Abstract: FIELD: oil producing industry, particularly, development of oil pools under complicated geological conditions characterized by zonal and bedding nonuniformly of pool with ruggedness coefficient of 5 and more. SUBSTANCE: method includes injection of working agent into at least one injection well and oil withdrawal from at least one producing well hydrodynamically connected with one or several injection wells. In this case, determined preliminarily in injection well is injectivity of at least one producing formation in oil pool depending on injection pressure and with control of covering the producing formation thickness with injected agent. Upon attaining complete covering of producing formation, characterized by efficient pressure and injectivity, injection pressure is further increased by increase of injected agent flow rate up to critical values, characterized by sharp increase of producing formation injectivity. After that, injection pressure is reduced to values below attained critical one but not below the efficient pressure, and injected into producing formation of injection well is fringe of emulsion composition up to sharp increase of injection pressure above 30% but within limits of critical pressure. Then working agent is injected with pressure reduced by 10-15% and injection of working agent is continued with commercial withdrawal of oil through producing well. EFFECT: increased oil recovery factor of pool due to provision of practically piston displacement of oil with minimal power consumption due to preliminary opening of closed natural vertical fractures of pool before its treatment. 10 cl, 1 ex
