    摘要： An apparatus for generating a large perforation in a target such as a wellbore casing. A liner is positioned within a charge case lowered into a well. An explosive material is initiated to collapse the liner to form a material penetrating jet. A spoiler is positioned proximate to the liner to defocus the liner collapse. The spoiler forms a hollow center in the material penetrating jet and concentrates the energy of the jet into a large annular ring for penetrating the target. The spoiler can comprise a passive spoiler which blocks the full collapse of the liner, or can comprise an active spoiler incorporating a high explosive or an elastic material for counteracting the liner collapse. The spoilers can be spherical, cylindrical, tapered, or another shape to modify the configuration and performance of the material penetrating jet, and a spacer can retain a spoiler in a selected orientation relative to the liner.

    摘要翻译： 用于在诸如井筒壳体的靶中产生大的穿孔的装置。 衬垫位于一个放入井内的充电箱内。 启动爆炸性材料以使衬套折叠以形成穿透射流的材料。 扰流板定位成靠近衬垫以使衬里塌陷。 扰流板在材料穿透射流中形成中空中心，并将射流的能量集中到用于穿透目标的大环形环中。 扰流器可以包括阻挡衬套的完全塌陷的被动扰流板，或者可以包括结合有用于抵抗衬套塌陷的高爆炸物或弹性材料的主动扰流器。 扰流板可以是球形，圆柱形，锥形或另一种形状，以改变材料穿透射流的构造和性能，并且间隔件可以相对于衬套将扰流板保持在选定的方位。

    摘要： A technique that is usable with a well includes communicating a ballistic wave from a first point in a well to a second point in the well without propagating the ballistic wave along a detonating cord. The first and second points are separated by at least one foot. The technique includes responding to the ballistic wave near the second point to activate a downhole tool.
