成果简介	NOVELTY - Invention relates to oil industry and can be used for intensification of oil production from productive formations by hydraulic fracturing (HF). Disclosed is a method for hydraulic fracturing of low-permeability formations, in which calibration pumping is performed, the number of hydraulic fracturing stages in the hydraulic fracturing simulator is calculated based on specific geomechanical conditions in the formation in the hydraulic fracturing zone at a predetermined mass and fraction of proppant per one hydraulic fracturing operation, after that, the main hydraulic fracturing is performed, which includes repetition of at least three consecutive stages: pumping of low-viscosity fracturing fluid into the formation and further pumping of high-viscosity fluid with coarse fraction proppant with gradual increase of maximum concentration of proppant. After the main hydraulic fracturing, the final stage of hydraulic fracturing is performed by replacing high-viscosity fluid in the well with low-viscosity fluid. USE - Oil industry. ADVANTAGE - Increasing productivity of wells with hydraulic fracturing due to creation of high-conductivity fracture of hydraulic fracturing with vertical coverage of productive part of formation and with stable hydrodynamic connection with borehole. 1 cl, 6 dwg, 2 tbl
