Abstract

FIELD: mining industry; applicable in formation opening in oil and gas wells. SUBSTANCE: jet charges are arranged in individual tight cases. Perforator has body in form of tube with through holes in its side wall which are oriented square to body axis. Installed in holes are airtight cases with charges. Diameter of each hole is taken to ensure overlapping of each hole in transportation position with airtight case and fasteners. The given jet perforator lowered on the pipes ensures preliminary washing of perforation interval and provides for control of its operation. Besides, the jet perforator ensures qualitative exposure of formation under conditions of depression. EFFECT: higher efficiency of perforator due to increased penetrative ability with use of increased sizes of each charge and removal of additional obstacles on the jet stream path with simultaneous increase of its reliability and design simplification. 3 cl, 2 dwg
