FIELD: oil and gas industry.
SUBSTANCE: method of acoustical impact on oil formation involves impact at acoustical or ultrasonic frequencies and at low acoustical frequencies - 20 Hz or 50 Hz. Length of packs of acoustical or ultrasonic impact is half the period, which is chosen for low acoustical frequency impact. Acoustical impact on oil formation includes acoustical emitter, operating frequency - 8-25 kHz and generator of packs of strong electrical signals at operating frequency of acoustical emitter.
EFFECT: increasing formation oil recovery and improving the device reliability.
