METHOD AND SYSTEM FOR PROCESSING OF UNDERGROUND FORMATION WITH USE OF DEVIATION OF PROCESSING FLUID MEDIA (VERSIONS) Russian patent published in 2011 - IPC E21B43/14 E21B43/26 

FIELD: mining.

SUBSTANCE: method involves the following stages: a) hydraulic interconnection between the well and at least one target area for processing in underground formation crossed with the well; b) arrangement in the well of tubing string; c) introduction to the well of treatment solution; d) contact of target zone in underground formation with treatment compound; e) introduction of deflecting agent through tubing string to the interval in the well; repetition of stages c) and d) for more than more target zone; at that, control of micro-seismic vibrations is performed at the treatment; and as per the above vibrations there determined are sizes of the treated zone or propagation of the treatment beyond the limits of the treated zone; on the basis of that, modes of introduction of treatment compound or its properties are changed or deflecting agent is introduced.

EFFECT: increasing the efficiency of the method and improving the system operating reliability.
