PROCEDURE OF HYDRAULIC BREAK OF RESERVOIR IN WELL Russian patent published in 2009 - IPC E21B43/26 

FIELD: mining.

SUBSTANCE: method consists in perforating walls of well with channels of depth not less, than extent of zone of stresses concentration in rock from borehole of existing well and in pumping gel like fluid of break "Kchimeko" by portions: first of volume 3-8 m³, second of volume 10-12 m³, third of volume 2-3 m³. Further there is performed driving of portions of gel like fluid into the reservoir at consumption of 0.5-1 m³/min.

EFFECT: facilitating partial mode load of hydraulic break of reservoir with exposing mud zone by extensive network of fractures with initial pressure of break below pressure of classical break and by implementing less amount of break agent.
