METHOD FOR PULSE TREATMENT OF WELL Russian patent published in 1995 - IPC

FIELD: mining industry. SUBSTANCE: prior to treatment, source of pressure pulses and transducer for registration of amplitude of pressure pulses are moved from nonperforated part of well along filter, and pressure pulse amplitude is measured in source zone. Relation P_f(H)/P_к, is determined, where P_f(H) and P_к are amplitudes in filter interval at depth H and in well nonperforated part, respectively. Then, permeability of different intervals of filter is estimated, and well is treated with pressure pulses with consideration of information obtained. Periodically during treatment, measurements of pressure pulse amplitudes are repeated in source zone. Completion of treatment is estimated by stabilization of values of said relation. Method allows considerable increase of treatment selectivity and reduces its terms. EFFECT: higher efficiency due to revealing filter intervals of low permeability with simultaneous control of the process of restoration of permeability. 2 dwg
