Abstract

FIELD: means for protection of oil field equipment from corrosion in mineralized aqueous media; applicable in oil producing industry. SUBSTANCE: corrosion inhibitor contains product of reaction of oxyethylated fatty alcohol or oxyethylated alkyl phenol, phosphorous acid and ethanol amine of basic formula HN(CHOH), where n=1,2,3 taken in molar ratio of 1:(0.8-1.2): (0.8-1.2), respectively. Preferred version of the corrosion inhibitor contains reaction product indicated above and solvent in the following amount of components, mas.%: above-indicated reaction product 20-80; the balance, solvent. EFFECT: higher protective effect from hydrogen sulfide and oxygen corrosion.
