FIELD: oil and gas industry.
SUBSTANCE: invention relates to the oil and gas industry, in particular, to the technology of oil production using chemicals for processing the bottom-hole zone of the formation, restoring or increasing its permeability. The chemical reagent for the treatment of the bottom-hole zone of the oil well formation contains potassium fluoride peroxosolvate KF∙H2O2, hydrochloric acid HCl and water at the following component ratio, wt. %: KF∙H2O2 2.5-7.5; HCl 2.5-7.5; water being the rest. The chemical reagent for the treatment of the bottom-hole zone of the oil well formation may additionally contain an ionic or non-ionic surfactant in an amount of 0.1-2.5 wt. %, and corrosion inhibitor in the amount of 0.01-5.0 wt. %.
EFFECT: increase in the efficiency of processing the bottom-hole zone of the oil well formation when using the reagent with a simultaneous increase in the environmental safety of its use.
