FIELD: corrosion protection. SUBSTANCE: invention relates to agents protecting equipment against corrosion and can be used in oil production industry wherein equipment is exposed to attack of hydrogen sulfide and/or oxygen, or carbon dioxide. Inhibitor includes primary C8-C25-amines or their mixtures, nonionic surfactant, and solvent, in particular methanol and higher aromatic hydrocarbons, and, in addition, monoethanolamine, weight ratio of amines to surfactant being (1- 3):1. Components are mixed successively: monoethanolamine is first added to surfactant, then solvent and primary amines. EFFECT: increased corrosion inhibition efficiency. 2 cl, 2 tbl _
