oil producing industry, particularly, methods of control of oil formation development by restriction of water inflow to producing wells and equalization of injectivity in injection wells. SUBSTANCE: method includes successively alternating injection into formation of water-soluble polymer, aqueous solution of alkali and aqueous solution of aluminum salt. Alkali is used in the form of aqueous solution of sodium silicate or alkaline sewer of caprolactam production of 8.0-15.0% concentration. Aluminum salt is used in the form of alumino-containing wastes of benzene alkylation with olefin of 5.0-25.0% concentration. Additionally injected is spacer fluid between injections of water-soluble polymer, aqueous solution of alkali and aqueous solution of aluminum salt. In the last cycle, injection of water-soluble polymer is conducted with introduction of chromium acetate into it. EFFECT: increased oil production due to treatment of high-permeability formation zones by reduction of their permeability. 2 cl, 1 tbl
