    摘要： A gun system in one arrangement includes a first carrier including a detonating cord and a second carrier including a detonating cord. An adapter couples the first and second carriers, with the adapter including an explosive coupled to the detonating cord of one of the first and second carriers. The explosive is positioned in a reduced housing portion of the adapter. The reduced housing portion of the adapter has a first outer diameter less than an inner diameter of the first carrier to provide a predetermined annular space between the reduced adapter portion and the inner diameter of the first carrier. At least one of the detonating cords in the first and second carriers is attached to a retainer element, and the retainer element is placed in close proximity to the explosive to maintain an axial position of the detonating cord to reduce separation between the detonating cord and the explosive. In addition, the explosive is placed some axial distance away from sensitive elements in the adapter, such as sealing elements and connector elements, to protect the sensitive elements from detonation of the explosive.

    摘要： A liner for a shaped charge is disclosed which comprises a plurality of portions, where at least one portion is composed of powder materials. In one embodiment, the liner comprises two portions that are composed of different powder materials, while alternative embodiments of the liner comprise three portions or four portions. When the shaped charge is used in a perforating gun, reactive powder materials may be added to the plurality of portions of the liner to optimize the penetration or the enhancement of the perforating tunnel.

    摘要： A radial-linear shaped charge pipe cutter is constructed with the booster explosive packed intimately into a booster aperture that is bored axially through the charge upper end plate. The cutter explosive is initiated at the interface between the upper margin of the cutter explosive and the contiguous inside surface of the upper end plate. This interface is within a critical initiation distance from the half charge juncture plane. In one embodiment, a half charge liner is configured as the assembly of two, coaxial, frusto-cones with the smaller cone diverging from the half charge juncture plane at a smaller angle than the outer cone. In another embodiment, the liner thickness increases from the juncture plane out to the liner perimeter.
