JET PERFORATOR CARRIER Russian patent published in 2002 - IPC

FIELD: oil and gas producing industry; used in perforators designed for blasting perforations in oil and gas wells. SUBSTANCE: jet perforator carrier has through, stepped holes for charges sealed during its lowering into well. Said holes are made in opposite wall of carrier which are opposite to through holes, and on their axis, nonthrough holes for charge shanks are provided. All holes are made conical on part of their length to provide for sliding of periphery part of charge jet stream, direction of resulting force to side of large section of carrier wall and reduction of vertical component force by a factor of 1.5 from resulting force. Large diameter of cones exceeds diameter of charge funnel and diameter of shank, respectively. EFFECT: reduced damage of perforator carrier by jet stream and charge reactive recoil after its blasting and increased serviceability of carrier by several times. 2 cl, 2 dwg
