FIELD: corrosion protection.
SUBSTANCE: invention can be used in the oil industry for acid treatment of boreholes, as well as for treatment of the bottomhole zone of oil and water injection wells. 1,3-dimethyl-2-(4-mercaptophenyl)imidazolidine compound with the formula 
is proposed to use St3 steel as a corrosion inhibitor in the concentration range of 100-400 mg/l in a 15% aqueous solution of hydrochloric acid at a temperature of 25°C.
EFFECT: corrosion rate of steel St3 in the presence of 1,3-dimethyl-2-(4-mercaptophenyl)imidazolidine is reduced from 13.5 mm/year in a non-inhibited solution to 1.8 mm/year.
