FIELD: chemistry.
SUBSTANCE: present invention pertains to the oil producing industry, particularly to petroleum production engineering using acidic mixtures for treating a carbonate layer of a wellbore area. The mixture for acidic treatment of a carbonate layer of a wellbore area contains, in vol. %: light oil 78-82, 15% aqueous solution of sulphaminic acid 17.93-21.9, surface-active substance "АФБ"-9-12 0.07-0.1.
EFFECT: lower rate of reaction of the mixture with the carbonate rock layer and increased radius of the layer of the wellbore area by acid reaction.
