    摘要: A system and method for making and using a multi-point initiation explosive device that produces an enhanced pressure wave for severing tubing, pipe or casing in an oil or gas well. At least two opposed initiators initiate a column of explosive material from opposite ends, thereby generating opposing pressure waves propagating toward a midpoint between the initial initiators. A shaped-charge assembly with a liner located at the midpoint initiates immediately prior to the arrival of the opposing pressure waves and forms a fast moving jet to pre-score the target pipe prior to the arrival of the pressure pulse propagating from the initial detonations.

    摘要: A system and method for a packaging system for the shipment of high explosive components is described. One or more explosive devices are positioned in a tubing assembly having opposed ends and a thick wall of relatively low-density fibrous material, e.g. rolled paper tube. An impact absorbing element is positioned at each end of the tube. The impact absorbing element may include an end cap positioned within each end of the tube, and a cushion formed of partial tubes and an end cap. The complete assembly is sized to fit and be held in position by a standard shipping container. Multiple perforating charges in a tubing assembly may face opposite sides of a charge divider. Shaped charges may have their concave openings filled with a jet interrupter, e.g. sand. Circular charges may include heat releasable fasteners, e.g. nylon screws, which allow the charges to separate in case of fire.

    摘要: A detonator assembly is provided. The detonator assembly comprises a deflagration to detonation transition body, a first thermally stable secondary explosive contained by the body, and a bulkhead coupled to the deflagration to detonation transition body. The bulkhead contains pressure within the body associated with firing the detonator assembly at least until a transition from a deflagration operation mode of the detonator assembly to a detonation operation mode of the detonator assembly has occurred. A second thermally stable secondary explosive may alternatively be included in the deflagration to detonation transition body, either separated from the first thermally stable secondary explosive or mixed with the first thermally stable secondary explosive. The detonator assembly comprises effectively no primary explosive.
