METHOD FOR PROCESSING FACE-ADJACENT ZONE OF WELL AND DEVICE FOR REALIZATION OF SAID METHOD Russian patent published in 2005 - IPC

FIELD: oil industry.

SUBSTANCE: in the well, pulse depression and repression effects on bed are formed in form of cycles of pulse depression-repression oscillations for swaying plugs, corking filtering channels. Pulse depression and repression effects are performed by multiple adjusted pressure pulses, which pressure appears during external thermal transformation of substances mixture, coinciding with own oscillations phase in well and in bed. Cyclically increasing amplitude is provided with providing of depression-repression oscillations pulses, equal to 15·n, where n - number of chambers, and next pressure pulse exceeds previous one, with time range τ=2πk, where k - proportionality coefficient, while number of pressure pulses is equal to chamber number. Effect on bed is performed using device, containing serially positioned implosion chambers with draining openings, geophysical head, geophysical cable. Implosion chambers are interconnected by link, isolating hollow of one chamber from another one and provided with hermetical wall. Through the latter electric conductors are let. Into each implosion chamber package with mix of substances is placed, which mix is capable of external thermal transformation, and provided with electric spiral, connected to independent ignition line.

EFFECT: higher efficiency.
