FIELD: oil production industry. SUBSTANCE: this relates to acid treatment of down-hole zone of bed for stimulating oil inflow. High technological and economic efficiency is reached by introduction of 15% muriatic acid into alumo-containing composition at ratio of 1:30 which leads to increased time of initiating interaction with carbonate material due to retarding hydrolysis reaction of alumochloride and reduction of possible gel-formation in 1.5-4.2 times. In result, radius of bed treatment is enhanced by 4-10 times as compared with conventional acid treatment. EFFECT: high efficiency. 3 tbl, 1 dwg
