    摘要: The present invention provides an apparatus for use in perforating a well having a plurality of explosive charges. Each explosive charge is adapted to generate a perforation tunnel in the formation adjacent to the well. In one embodiment, explosive charges are oriented to create perforation tunnels that converge at a location within the formation in order to create a fracture initiation plane capable of mitigating or avoiding hydraulic fracturing complications.

    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.
