ACOUSTIC RADIATING SYSTEM FOR INTENSIFICATION OF OIL PRODUCTION Russian patent published in 2016 - IPC E21B43/25 E21B28/00 

FIELD: oil industry.

SUBSTANCE: invention relates to oil industry and can be used to prevent scaling in oil production equipment during oil production intensification. Acoustic radiating system for intensification of oil production includes in-series connected multichannel master generator, multichannel phase-pulse modulator, multichannel key power amplifier, first matching device, first filtration device, which forms a transmitting channel of the first process frequency range, as well as a logging cable and acoustic radiators of the first and second process frequency range. Wherein the output of the first filtration device through logging cable is connected to the acoustic radiator of the first process frequency range. Also the acoustic system further includes a process cable and technological chamber, as well as a transmitting channel of the second process frequency range consisting of series-connected single-channel master oscillator, single-channel phase-pulse modulator, single-channel key power amplifier, second matching device and second filtration device of. Wherein the output of the second filtration device through process cable is connected to the acoustic radiator of the second frequency range. Acoustic radiator of the first process frequency range is installed in the productive zone of oil wells and the acoustic radiator of second frequency band is located in the process chamber included in the field pipeline.

EFFECT: technical result is prevention of scaling in oil production equipment.
