摘要

FIELD: oil, gas and coke-chemical industries.;SUBSTANCE: invention relates to oil and gas industry and can be used for stimulation of underground formation by means of hydraulic fracturing (HF) of formation, in particular, using mathematical modelling methods which allow prediction of fracture geometry of hydraulic fracturing and placement of liquids, proppants, fibres and other materials in it. Proposed method comprises input of data on hydraulic fracturing schedule, data input for hydraulic fracture crack propagation sub-model in formation. Data input for hydraulic fracturing material transport submodel in crack. Simulation of formation hydraulic fracturing using hydraulic fracturing crack propagation sub-model and hydraulic fracturing material transport submodel. At the same time conjugation of submodels is carried out by hydrodynamic resistance for simulation cells. Output of simulation data at the moment of hydraulic fracture schedule termination and/or fracture closure.;EFFECT: present solution is a method of prediction of hydraulic fracturing, which expands capabilities of existing pseudo-three-dimensional (P3D) approach.;13 cl, 11 dwg, 17 tbl
