FIELD: oil-and-gas industry.SUBSTANCE: proposed method comprises test forcing of fracturing fluid and pile of fracturing fluid with proppant, correcting the fracturing project and performing of the main fracturing process with forcing the fracturing fluid "pad". For hydraulic fracturing, multi-seam deposit with productive seams separated by impermeable 10 m deep bridge is selected. In compliance with corrected fracturing project, fracturing pressure is maintained sufficient to open fracturing fractures at two seams at a time, and the main fracturing process with forcing the fracturing fluid "pad" is performed in volume of at least 8 m. Fracturing fluid flow rate is maintained sufficient to open fracturing fractures at two seams at a time and to rule out closure of one of them. Bulk of forced proppant is defined with due allowance for fixture of fractures in two seams.EFFECT: hydraulic fracturing in two productive seams at a time.1 tbl |
