FIELD: oil production industry, particularly for drilling mud cleaning during oil and gas well boring.
SUBSTANCE: method for removing particulate contamination from mud inside sucking pipe provided with pump and storage vessel involves installing composite acoustic noise transducer to transform noise of quarter-wave resonators arranged along a circle inside suction pipe of mud pump; converting low-frequency drilling pump noise into ultrasound; forming standing wave in suction pipe for length equal to length of composite acoustic noise transducer; exerting influence of ultrasonic standing waves on particulate contamination coagulation and precipitating thereof into storage vessel.
EFFECT: increased cleaning efficiency.
