METHOD OF HYDRAULIC FRACTURING OF BED Russian patent published in 2012 - IPC E21B43/26 

FIELD: oil and gas industry.

SUBSTANCE: method includes isolation of a producing interval with a packer installed above the producing interval, but below the dynamic level in the well, injection of a fluid into the area under the packet via a tubing string, development of multiple hydraulic fractures in the bed. At the same time the fluid is injected with different intensity, its specified characteristics and account of hydraulic fracturing channel walls elasticity properties to ensure the possibility to develop pressure surges - hydraulic shocks in hydraulic fracturing channels at the specified distance from the well bore and increasing depth and/or height of these channels or formation of secondary hydraulic fractures in these channels.

EFFECT: higher efficiency of the method due to well productivity growth at low capacities of the used equipment of bed hydraulic fracturing and increased efficiency of perforation channels.
