FIELD: oil production industry. SUBSTANCE: application of composition for acid treatment allows for reducing speed of reaction of acid compound with rock ground, permits freeing of bed bottom hole zone from plugging components such as metal oxides, loose-cohesive water, water-oil emulsion, also allows for increasing oil inflow into producing wells and for enhancing injectivity of producing and injection wells. Acid treating composition has following components, mass%: surface-active matter, 0.5-5.0; water-repelling agent, 0.5-1.0; 12-24-% concentration muriatic acid, 94.0-99.0. EFFECT: higher efficiency. 1 tbl
