METHODS FOR INITIATION OF NEW FAULTS IN FINISHED WELL BORE, ALREADY CONTAINING FAULTS Russian patent published in 2016 - IPC E21B43/26 

Abstract RU 2578696 C1

FIELD: mining.

SUBSTANCE: invention relates to fracturing operations. Method for initiation of new faults in finished well bore, containing faults, comprises introduction of treatment liquid containing multiple destructed particles for sealing, in finished well bore, penetrating through underground formation with existing interruption, sealing of fracture at least part of destructed particles for sealing, forming a destructible plug of particles, destruction of said remained in liquid for processing, so that fluid is essentially free from particles, while said destructible plug of particles is an integer, and then fracturing an underground formation, to receive at least one new interruption. In another version, said method also includes a treatment liquid additive, increasing rate of destruction of destructed particles. In a third version, finished well shaft includes annular space limited by coupling of hydraulic fracturing and surface of underground formation. Invention is developed in dependent claims.

EFFECT: technical result is high efficiency of hydraulic fracturing in complete well bores with existing gaps.
