FIELD: oil and gas industry, particularly to exert seismoacoustic action on well bottom zone.
SUBSTANCE: method involves lowering seismoacoustic emitter into interval to be treated to reach oil-water contact level so that discharging container of seismoacoustic emitter is arranged in lower part thereof and space between seismoacoustic emitter body and well wall is 10-20 mm; lifting seismoacoustic emitter at 500-600 m/h speed to upper perforation orifices with emitting seismoacoustic pulses with repetition frequency of 1-2 Hz, distribution of modes of frequency equal to 20-10000 Hz, impulse duration of 0.2-0.5 mc and power of 50-100W; lowering seismoacoustic emitter to stable oil-water contact level and lifting thereof to upper perforation orifices simultaneously with emitting elastic seismoacoustic pulses to lift well fluid to new, higher, level in well.
EFFECT: enhanced well operation.
