FIELD: oil and gas producing industry, particularly, compositions for treatment of bottom-hole formation zone to increase well productivity and oil recovery. SUBSTANCE: composition for treatment of bottom- hole formation zone includes hydrochloric acid, acetic acid and corrosion inhibitor in form of Katapin-A, and additionally waste of paper production - lignosulfonate, with the following amount, of components, wt.%: hydrochloric acid 93.8-97.8; lignosulfonate 1.0- 5.0; acetic acid 0.5-1.0; Katapin-A 0.1-0.2. EFFECT: higher efficiency of treatment due to increased depth of penetration of composition into bottom-hole zone and fuller withdrawal of reaction products from formation, reduced cost of composition due to utilization of paper production wastes. 2 dwg, 1 tbl
