FORMATION HYDRAULIC FRACTURING FORMATION METHOD AND FORMATION HYDRAULIC FRACTURING METHOD Russian patent published in 2020 - IPC E21B43/267 

FIELD: mining.

SUBSTANCE: group of inventions relates to stimulation of productive formation using formation hydraulic fracturing technology (HF), in particular, to methods of hydraulic fracturing. Construction of the hydraulic fracturing plan in the well includes the following stages: obtaining data on operations of hydraulic fracturing of the formation, containing a plan for pumping of proppant and a plan for pumping of fibres of various types. Construction of a degradation matrix for fibres of different types. Construction of possible versions of hydraulic fracturing operation in compliance with type of fibre and pumping schedule. Also disclosed is a method of hydraulic fracturing of a formation, which comprises constructing a plan of hydraulic fracturing of a formation in a well, as well as preparation of a hydraulic fracturing fluid containing a carrier fluid, proppant, additives and fibres, and pumping of hydraulic fracturing fluid into the formation through the well according to the selected optimal option of the hydraulic fracturing operation.

EFFECT: technical result consists in optimization of formation hydraulic fracturing plan taking into account two-dimensional simulation of transfer processes in hydraulic fracturing.
