More Information
Summary:oil producing industry, particularly, methods of restriction of water inflows to producing oil wells and equalization of injectivity profile of injection wells. SUBSTANCE: method includes injection into formation of water repellant, emulsion of intermediate layer of oil treatment process and disperse medium. Preliminarily introduced into said emulsion are water repellant and disperse medium in ratio of 1:0.001:0.005, respectively. EFFECT: higher efficiency of shutoff operations due to restriction of water inflow into producing wells and equalization of injectivity profile of injection wells. 1 tbl
