摘要
A perforating gun includes a base strip having an angular cross section, the base strip being a single unitary structure and essentially comprising at least two longitudinally disposed surfaces, a first surface and a second surface, a first plurality of capsule charges being connected to the first surface and a second plurality of capsule charges being connected to the second surface and interleaved with the first plurality of capsule charges, thereby phasing the capsule charges in the perforating gun. Since the gun utilizes capsule charges, good penetration into the formation is achieved. Due to the cross sectional configuration of the base strip, the phased capsule charges, when mounted on the strip, will easily fit within a tubing string previously used by non-phased capsule charge perforating guns. Since the base strip is a single, unitary structure, it is rugged enough to avoid shattering upon impact with an obstruction in a borehole, yet, due to its chemical and mechanical properties, will shatter in response to detonation of the capsule charges.
