FIELD: petroleum-extractive industry, more particularly control on corrosion of oil field equipment. SUBSTANCE: claimed composition comprises 2-alkylimidazolines of stillage residues resulting from production of synthetic fatty acids; 12.0-15.0 wt. % surfactant; 3.0-5.0 wt.% cracking residue resulting from oil refining; 5.0-8.0 hydrocarbon solvent containing aromatic hydrocarbons, e. g. aromatic nephras A 120/200 or A 150/330, the balance. The degree of protection of steel in oil field media having high oxygen content in hydrogen sulfide is 85-96%. EFFECT: improved properties of the composition. 1 tbl
