FIELD: oil and gas industry.
SUBSTANCE: device comprises a source of acoustic vibrations installed inside the well strainer and coupled to the computer by a logging cable. A resonator is suspended at a logging cable near the source of acoustic vibrations while the source of acoustic vibrations is designed to change pulsation frequency for automatic setting of resonant frequency equal to the resonator frequency.
EFFECT: raised efficiency of cleanup and reduced time.
