FIELD: corrosion protection. SUBSTANCE: inhibitor contains 3-15% phosphoric acid di(alkylpolyethylenglycol) ester potassium salt, 0.5-10% alkylimidozoline derivative, 0.5-20% methanol, and 60-89,5% mixture of aliphatic and aromatic hydrocarbons including ethylbenzene and styrene derivatives. Inhibitor can be employed in oil production industry. EFFECT: increased level of protection effect at satisfactory process characteristics: reproducibility of high protective effect for media strongly differing in mineralization, oxygen and hydrogen sulfide contents, and also in liquid stream speed. 1 tbl
