Zusammenfassung:A method of stimulating the inflow of oil and/or gas from the wellbore, in particular, a hydraulic fracturing method, is disclosed. The method of hydraulic fracturing comprises the stages: injecting a slug of a proppant-free fluid through the well into a formation for hydraulic fracture creation and propagation; injecting a slug of proppant-laden slurry into the formation to create a proppant pack in the hydraulic fracture; injecting a slug of slurry that contains a fluid and the polyelectrolyte complex-based proppant aggregates to create permeable channels in the near-wellbore area of the hydraulic fracture; injecting a slug of a displacement fluid into the well. This sequence of operations allows avoiding the proppant slurry overdisplacement deep into the hydraulic fracture, maintaining high fracture conductivity, and increasing the well productivity.
