FIELD: oil production industry. SUBSTANCE: according to method, prepared is viscous-elastic compound and then it is injected at pressure which is by 50-90% lower than nominal value of flooding pressure. Volumes of injection are as follows: 110-120 cu.m, 120-250 cu.m, 250-500 cu.m, 500-750 cu.m per 1 m of absorbing thickness of bed. Injectivity of wells being correspondingly from 50 to 100 cu.m/day, from 100 to 200 cu.m/day, from 200 to 300 cu. m/day, from 300 to 1000 cu.m/day. Application of method increases oil recovery from bed. EFFECT: higher efficiency. 1 dwg
