METHOD OF PLANNING OPERATING AND INJECTION WELLS Russian patent published in 2019 - IPC E21B43/267 E21B28/00 C09K8/80 

FIELD: mining.

SUBSTANCE: invention relates to mining and can be used for formation hydraulic fracturing. Method comprises steps of: pumping into a well shaft of a hydraulic fracturing fluid medium which does not contain a propping agent, forming a fracture in the formation, hydraulic fracturing fluid medium is injected into the well shaft, pulse mode of injection includes at least one pumping pulse of hydraulic fracturing fluid medium containing propping agent, and at least one pumping pulse of hydraulic fracturing fluid medium, which does not contain propping agent, wherein during the hydraulic fracturing fluid medium injection impulse containing the propping agent, additionally add the strengthening and/or consolidating material into the hydraulic fracturing fluid medium, wherein concentration of strengthening and/or consolidating material is increased in hydraulic fracturing fluid medium injection pulse containing propping agent, wherein miltiplication of volume rate of fluid medium (V) of hydraulic fracturing (l/s) by viscosity (μ) of hydraulic fracturing fluid medium (Pa*s) does not exceed 0.003 Pa*l at hydraulic fracturing.

EFFECT: higher efficiency of formation hydraulic fracturing due to reduced action of liquid on crack walls and wedging agent clusters.
