Abstract

Перфорирующий инструмент включает в себя заключенный в оболочку кумулятивный заряд, который имеет перегородку с частью уменьшенной толщины, пластину, имеющую неглубокое углубление, и детонационный шнур, имеющий энергетический сердечник. Энергетический сердечник образует при детонации из пластины взрывной перфоратор. Пластина установлена с возможностью направления взрывного перфоратора в часть с уменьшенной толщиной.
