FIELD: oil and gas industry.
SUBSTANCE: invention refers to oil and gas area. Created fracture cleaning process involves delivery of proppant-containing working fracturing liquid and the agent producing inorganic acid to the created fracture. Herewith specified agent is polyvinylidene chloride particles sized within 0.0001 to 0.05 mm. Invention is developed in dependent clause.
EFFECT: augmented formation fluid flow to the borehole cavity ensured by created initial fracture surface cleaning, as well as by its greater area.
