Summary:FIELD: oil production industry. SUBSTANCE: method is aimed at involving low-permeable oil-saturated sections of bed in developing activities and increasing their producing capacity. According to method, simultaneously injected into oil bed through injection well are polymer solution and water solution of alkali. Then injected is water solution of salt of polyvalent metal, and additionally pumped in is water solution of calcium chloride. This is performed prior to injection of displacing agent. EFFECT: higher efficiency. 3 cl, 2 tblr
