FIELD: oil and gas industry.
SUBSTANCE: invention refers to the field of oil and gas production, in particular to shooting and blasting operations, and can be used in order to form the cumulative load jet. Casing of the cumulative perforator is made with spherical recesses at the locations of the cumulative loads. Ratio of the radius of the spherical recess to the diameter of the perforator body is (0.2÷0.8):1. Ratio of the thickness of the thinned wall of the body in the area of the recess to the diameter of the body is 1:(15÷30).
EFFECT: significant reduction in the deformation of the perforator body is provided, minimizing the amount of burrs on the body in the zone of punched openings, ensuring high resistance of the perforator body to hydrostatic pressure.
