FIELD: oil industry.
SUBSTANCE: invention relates to oil industry and can be used in developing oil deposit. Method of repeated hydraulic fracturing is characterized by the fact that pumping of fracturing fluid at technology and conditions according to the first hydraulic fracturing of formation in it at the stage of adding cross-linking agent is added in amount of 1-2 l per 1 m3 of fracturing fluid mixture containing, vol%: 10-27 % hydrochloric acid 15-25, methylene-phosphoric acid 55-65, water 15-25.
EFFECT: technical result is increased efficiency.
