FIELD: oil production industry, particularly to develop oil deposits and clean water wells and ore holes.
SUBSTANCE: device comprises composite acoustic emitter made as piezoelectric rod cased with sealed body and two active disc-shaped emitting covering members located outside the sealed body. Each active covering member has at least one flat emitting surface directed transversely to longitudinal device axis. Acoustic emitter is provided with at least one metal reflector installed on outer emitted body surface and having flat surfaces, which are parallel to flat surfaces of active emitting covering members. The emitter is arranged on outer emitter body surface so that the emitter may slide along device axis and may be fixed in predetermined position.
EFFECT: increased acoustic field intensity in bottom zone inside casing pipe and in well area regardless of inner casing pipe diameter.
