FIELD: oil production industry. SUBSTANCE: this relates to development of oil deposits by means of flooding. According to method, water is injected through injection wells with addition of chemical reagent. Oil is recovered through producing wells. Used as additive is electrolyte. Concentration of electrolyte in water is selected to be such that ratio of electrical conductivity of water solution of electrolyte and electrical conductivity of water is not less than 2. Application of aforesaid method ensures increase of oil recovery due to larger embracing of bed by flooding and higher injectivity of injection wells. EFFECT: higher efficiency. 4 dwg, 1 tbl
