Abstract
FIELD: equipment for perforation and treatment of bottom-hole formation zone. SUBSTANCE: device for perforation and treatment of bottom-hole formation zone has additional sealed body-air chamber with atmospheric pressure inside located between device body and the head of regular hollow-carrier jet-type perforator. This provides, with the help of one device, for performance of perforation and implosive treatment of bottom-hole formation zone, after opening of side holes in perforator body, that promotes removal from channels and fractures of formation of contaminations including those formed by remains of jet charge and jet. EFFECT: higher efficiency. 1 dwg
