摘要： A perforating tool includes an encapsulated shaped charge that has a bulkhead with a reduced wall thickness section, a plate having a shallow recess, and a detonating cord having an energetic core. The energetic core forms the plate into an explosively formed perforator when detonated. The plate is positioned to direct the explosively formed perforator into the reduced wall thickness section.

摘要： A shaped charge assembly (10) comprises a housing (20), first shaped charge (24), a wave shaping relay charge (44) and a second shaped charge (30) located in the housing. The assembly (10) is configured such that a first active element formed by initiation of the first shaped charge (24) causes detonation of the wave shaping relay charge (44), which in turn causes initiation of the second shaped charge (30) to form a second active element. The first active element moves beyond a second end (25) of the housing to cause damage of a first kind to an external target and the second active element also moves beyond the second end to cause damage of a second kind to the target.
