FIELD: breaking of productive collector by perforation under pressure in oil and gas production industries. SUBSTANCE: gear includes tubing string, circulation valve, packer, filter and perforator. It also has face pressure pulsator with valve. It is capable of alternate opening and shutting of valve for short-time communication of space of tubing string with space above packer and for barodynamic treatment of face zone of pool. Gear carries depth remote instruments for control over perforation, for barodynamic treatment and test of pool, mechanism with cable section and electric contact tip. It is located inside internal space of gear to transmit electric energy from surface to measuring instruments and perforator. EFFECT: widened functional capabilities and increased operational reliability of gear. 1 cl, 4 dwg
