FIELD: protection for oil extracting equipment operating in hydrogen sulfide-containing corrosive media against attack by corrosion; oil production and associated industries. SUBSTANCE: organic solvent, fatty acid, non-ionogenic surfactant and aminoparaffin taken in succession are mixed. They are taken in the following ratio, mas.%: fatty acid, 8-20; non-ionogenic surfactant, 12-28; aminoparaffin, 2-8; organic solvent, the balance. EFFECT: highly efficiency of corrosion inhibitor. 1 tbl
