FIELD: oil and gas industry.
SUBSTANCE: in treatment method of bottom-hole zone of an oil formation, which involves series pumping of hydrocarbon solution of the product based on non-ionogenic surface active substance and acid-containing reagent, as hydrocarbon solution of the product based on non-ionogenic surface active substance there used is hydrocarbon solution of emulsifier of inverted emulsion of hydrocarbon solution of a mixture of non-ionogenic surface active substances, or hydrocarbon solution of a mixture of non-ionogenic surface active substances with anionic surface active substances, which is forced through with water to the formation; exposure is performed during 1-24 hours; after that, acid-containing reagent is pumped and forced-through with water to the formation.
EFFECT: improving treatment efficiency.
