摘要： The present invention is concerned with severing tubing, pipe or casing in an oil or gas well, and more particularly with 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. One embodiment uses at least two opposed initiators to initiate a column of explosive material from opposite ends, thereby generating opposing pressure waves propagating toward a midpoint between the initial initiators and a shaped-charge assembly with a liner located at the midpoint that initiates immediately prior to the arrival of the opposing pressure waves and that is intended to form an initial, 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.
