FIELD: oil-and-gas production.
SUBSTANCE: propping agent granule, based on a substratum and resinous coating - resinous layer, its external surface covered with at least one more extra coating - extra layer, consisting of mixture of low density polyethylene and paraffin with 7:3 ration, which has secure function against at least resinous layer parasitic reactions with chemicals from hydraulic fracturing fluid, and polymer destroyers, thickness of the extra layer is from 10 up to 30 mcm. Method of hydraulic fracturing execution includes pumping propping agent - mentioned above propping granules, into hydraulic fracturing slot.
EFFECT: keeping of polymer fluid required viscosity along the hydraulic fracturing procedure, prevention of propping agent early settlement into the slot, increase of consolidated propping pack strength, better slot cleaning out of polymer gel remains.
