FORMATION HYDRAULIC FRACTURING DEVICE Russian patent published in 2017 - IPC E21B43/26 E21B36/00 E21B43/24 

FIELD: mining.

SUBSTANCE: group of inventions relates to methods and devices for formation hydraulic fracturing. Formation hydraulic fracturing device of contains substantially tubular housing, injected fluid medium supply connection device and, at least, one high pressure steam-gas generator. At that, tubular housing is made with possibility of installation in well shaft working face area. At that, housing has, at least, one delivery opening next to its end. Connection device is functionally connected to housing for supply of consumable materials in form of fluid hydraulic fracturing medium inside formation hydraulic fracturing device housing. High-pressure steam-gas generator is installed in housing and contains, at least, one combustion chamber. At that, housing has combustible medium connection device, hydraulically communicated with, at least, one combustion chamber. Besides, at least, steam-gas generator is made with possibility of and intended for creation of ignition repeating cycles. At that, every ignition cycle comprises fuel supply cycle, intended for combustible medium supply, containing air and fuel, to, at least, one steam-gas generator, and combustion cycle, intended for supplied combustible medium ignition for pressure generation, produced as result of combustible medium combustion during combustion cycle, which pushes hydraulic fracturing fluid medium from, at least, one discharge opening.

EFFECT: technical result is reducing amount of hydraulic fracturing fluid.
