FIELD: oil production industry, particularly drilling mud cleaning during oil and gas well drilling.
SUBSTANCE: method for drilling mud cleaning in suction tube provided with pump and mud pit involves installing composite acoustic noise transducer made of quarter-wave resonators in suction tube of mud pump; converting low-frequency noise generated by mud pump in ultrasound; forming ultrasonic standing waves in suction tube over length equal to composite acoustic noise transducer length; applying standing ultrasound wave action in suction pipe on mechanical impurity coagulation and precipitating thereof in mud pit.
EFFECT: increased cleaning efficiency.
