Abstract

Скважинный перфоратор (60) для создания каналов, по которым флюид может протекать между пластом (64) и стволом скважины, облицованным обсадной трубой (66), содержит корпус (84), детонатор (86), установленный внутри корпуса (80), и детонационный шнур (90), функционально связанный с детонатором (86). Перфоратор (60) содержит также одну или более групп (92, 94, 96, 98) кумулятивных зарядов, установленных с взаимным смещением вдоль его продольной оси. Каждый из кумулятивных зарядов в группах (92, 94, 96, 98) функционально связан с детонационным шнуром (90). При этом смежные кумулятивные заряды в каждой группе (92, 94, 96, 98) кумулятивных зарядов ориентированы таким образом, что их оси сходятся в одной точке. Благодаря этому, детонируя, кумулятивные заряды в каждой из групп (92, 94, 96, 98) генерируют струи, которые взаимодействуют одна с другой с образованием в пласте (64) перфорационной полости.
