FIELD: oil, gas and water producing industry; applicable in secondary tapping of wells by shaped charge perforating. SUBSTANCE: jet perforator carrier has tube with through and blind holes for installation of jet charges, head and bottom part with through hole. Head and bottom part inside carrier are conical. Tube has additional radial through holes not intended for installation of jet charges. One part of them is made against conical parts of head and bottom part for redirection and acceleration of discharge of gases formed in explosion of charges and well fluid towards said holes. EFFECT: reduced dynamic forces acting on carrier in region of through and blind holes and also in threads. 1 dwg
