FIELD: oil and gas production. SUBSTANCE: composition contains 0.5-3 wt % of surface-active substance based on cationic and ampholytic surfactants and 97.0-99.5 wt % of 12-24% hydrochloric acid. EFFECT: increased oil-washing capacity of composition due to reduced composition-oil interfacial tension and corresponding increase in output of production wells and injectivity of injection wells at lower surfactant concentrations. 1 tbl
