摘要： A shaped charge assembly for use in a perforating gun that comprises a shaped charge holder, two or more shaped charges, slots formed to receive the shaped charges, and an impedance barrier disposed between adjacent shaped charges. The impedance barrier can comprise a gap formed in the shaped charge holder, where the impedance barrier runs across the shaped charge holder. The impedance barrier can be a void formed on the surface of the shaped charge holder, or can include shock attenuating material therein, such as wood, cork, cotton, polymeric materials, and combinations thereof, to name a few.

摘要： A shaped charge assembly for use in a perforating gun that further comprises a charge carrier, and gun housing. The charge carrier substantially encapsulates the closed portion of the shaped charge and extends from the outer periphery of the shaped charge to the inner diameter of the associated gun housing. Encapsulating the shaped charge substantially reduces the introduction of debris into the wellbore resulting from detonation of the perforating gun shaped charges. The charge carrier can include a multiplicity of shaped charges therein.

摘要： A shaped charge for generating a large hole in material such as well casing downhole in a wellbore. A shaped charge liner is oriented about a longitudinal axis, and a disk is positioned at the liner apex. When an explosive material is initiated the liner collapses into a perforating jet. The disk alters the jet formation process and changes the shape and location of a bulge within the perforating jet. Consequently, the shape of the perforating jet retains a larger diameter for generating a larger hole in the material to be perforated or for controlling the penetration depth. The disk surfaces can be flat, concave, convex or other shapes, and the disk composition can be varied to accomplish different design criteria.

摘要： A Controlled-Harm Explosive Reactive Armor (COHERA) is made of explosive layered between two plates of material with predetermined fragmentation having controlled harm prevention properties. The fragmentation is predetermined and prevents harm to personnel and equipment nearby a reacting COHERA. The controlled harm prevention qualities of a COHERA are determined according to a Harm Specification and to accompanying harm delimiting parameters. Furthermore, the COHERA is configured to prevent sympathetic initiation.
