FIELD: oil and gas production.
SUBSTANCE: invention is directed to increase productivity of producing wells and intake capacity of injecting wells, for which it provides a reagent for treating bottomhole oil formation zone composed of 30-85% inhibited and partly hydrolyzed aluminum chloride, 0.1-10% surfactant, 1.0-1.5% potassium chloride, 10.0-69.0% solvent, and water (the balance). In the process of treating bottomhole oil formation zone, above-defined reagent is injected to well and forced into formation, after which reaction products withdrawn. Injection of reagent can be carried out cyclically and withdrawal of reaction products from bottomhole formation zone is carried out under depression conditions or by forcing into formation.
EFFECT: enhanced formation treatment efficiency.
