FIELD: oil production, particularly to change fluid flow structure with the use of ultrasound.
SUBSTANCE: method involves lowering acoustic resonator-oscillator having fluid flow disturbing means on surface thereof in well up to level located below fluid degassing initiation level; creating turbulent fluid flow; recording noise produced by interaction of fluid flow with disturbing means; summing above noise spectrum with spectrum of noise caused by fluid circulation through perforation orifices in bottomhole formation zone; converting summary frequencies of audio-frequency range into ultrasound and performing fluid degassing along with increase in differential pressure drawdown.
EFFECT: increased efficiency of oil production stimulation.
