FIELD: oil industry.
SUBSTANCE: invention relates to the field of metal corrosion protection and can be used to protect equipment and pipelines from corrosion in contact with saline water-oil media containing hydrogen sulfide in the oil industry. The method includes adding 2-cyclohexylaniline with a concentration of 25-200 mg / l to a mineralized water-oil medium containing hydrogen sulfide.
EFFECT: increased degree of corrosion protection of steel equipment - (87.9 - 96.04)% and decreased corrosion rate in the presence of 2-cyclohexylaniline by 8.3-25.3 times.
