JET PERFORATOR CARRIER Russian patent published in 2002 - IPC

FIELD: oil and gas producing industry; applicable in hollow-carrier jet-type perforators designed for well perforation. SUBSTANCE: jet perforator carrier has through holes to pass jet stream after charge blasting and sealed during its lowering into well. Located opposite to through holes at the same axes are blind holes for installation of charge shanks. Axes of oppositely located pairs of holes are successively displaced relative to each other through 90 deg to the same side. Distance between planes of hole pairs in cross-sections perpendicular to carrier axis equals diameter of charge in middle of its length section perpendicular to charge axis for mutual compensation of action of charge blasting. EFFECT: optimal location of hole pairs ensuring their maximum number, and reduced carrier deformation. 1 dwg
