摘要：
A perforating gun of a perforating gun system is provided including hollow charges positioned within a holding device. The holding device includes holes in which the hollow charges are inserted and secured. In an embodiment, the holes are arranged on at least one helix. In a further embodiment, the perforating gun provides collapsible and fragmentable components that minimize debris remaining in a wellbore upon detonation of the charges.
