FIELD: mining.
SUBSTANCE: invention relates to methods for restoring the productivity of boreholes and devices for cleaning downhole mesh filters without dismantling water-lifting equipment. Device includes an acoustic emitter and means of delivery. Emitter is made of a composite of the upper support plate connected in series with the node of rotation, a unit of two multidirectional ultrasonic transducers and an electric motor mounted on the lower support plate for the implementation of rotational oscillations of the ultrasonic transducer unit at an angle of 180°, the delivery vehicle reciprocates the acoustic emitter, ensuring that the inside surface of the filter is scanned with an ultrasonic fluid flow simultaneously along the axis and around the circumference of the filter.
EFFECT: increased efficiency of cleaning, reliability of work.
