Abstract

Скважинный перфоратор (110) для создания каналов, по которым флюид может протекать между пластом (64) и стволом скважины, облицованным обсадной грубой (116), содержит корпус, детонатор и детонационный шнур (136). Перфоратор (110) содержит также одну или более групп кумулятивных зарядов (122, 124, 126), каждый из которых функционально связан с детонационным шнуром (136). Перфорационная полость (152, 154) образуется в результате взаимодействия струй (141, 142), формируемых при детонации по меньшей мере двух кумулятивных зарядов (122, 126), которые создают в пласте (114) ослабленную зону (148) с последующей детонацией по меньшей мере одного кумулятивного заряда (124), который формирует струю (150), проходящую сквозь ослабленную зону (148).
