FIELD: oil and gas producing industry. SUBSTANCE: method periodic injection through injection wells of hydrocarbon fluid and gel-forming material, injection of displacement agent and oil withdrawal through producing wells. Hydrocarbon fluid is injected in form of wastes of oil refining - residual fuel oil in volume of 400-500 cu.m. Gel-forming material is used in form of hydrocarbon-base organosilicon compounds - organoethoxychlorosiloxane - product 119-204. Prior to injection of said hydrocarbons, water repellant is pumped through. EFFECT: water shutoff of water-bearing zones of formation equalized profile of injection well injectivity and increased oil recovery factor. 2 cl, 1 ex
