FIELD: corrosion protection. SUBSTANCE: inhibitor intended for protecting oil-field equipment against hydrogen sulfide and carbon dioxide corrosion is prepared by successively mixing product of interaction of organic acid with amine and ketone (5- 40%), organic acid (2-20%), and surfactant: oxyethylated monoalkylphenol or oxyethylated fatty alcohol or products of their interaction with phosphorus-containing compound and amine (10-25%) in solvent (balance). EFFECT: strengthened inhibitory property and increased stability of emulsions of inhibitor in mineralized media. 3 tbl, 20 ex
