Abstract
A perforating gun barrel for carrying a plurality of explosive charges in a spaced apart relationship comprises a plurality of tubular sections positioned with the ends of adjacent tubular sections end-to-end, with the end of one section overlapping the end of an adjacent section. A coupling member is disposed entirely internally of said tubular sections at each coupling location. A plurality of bolts extend through the overlapping ends of the adjacent tubular sections and are secured in the coupling member to prevent separation of the adjacent tubular sections at the coupling locations. Wiring for detonating the charge carried in each tubular section is routed through a passageway provided in the coupling member.
