摘要： A method and apparatus to protect explosive components used in various tools, such as tools for use in wellbores, includes a component with an adsorptive material. Example tools include perforating gun strings that include shaped charges, detonating cords, and booster explosives. Other tools may include surface tools containing explosive components. In these tools, a build up of corrosive gases or liquids may occur, which may cause damage to the explosive components. As a result, the structural integrity or reliability and thermal stability may be weakened or reduced. To reduce the amount of build up of corrosive gases or liquids, an adsorptive material is placed inside tools in the proximity of explosive components.

摘要： An apparatus and method is provided to reduce interference resulting from activation of explosive devices. One type of interference is charge-to-charge interference, and another type of interference is pre-shock interference between a detonating cord and an explosive, such as a shaped charge. To reduce interference, one or more shock impeding elements are placed proximal one or more explosives to impede propagation of shock caused by detonation of the explosives. The shock impeding elements include a porous material, such as a porous liquid or solid. In another arrangement, a shock barrier may be positioned between a detonating cord and an explosive to reduce pre-shock interference. In yet another feature, an encapsulant may be provided around one or more shaped charges to enhance structural support for the shaped charges.

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.

摘要： An apparatus that is usable with a well includes a perforating system that is adapted to be fired downhole in the well. The perforating system includes a component, which includes an alloy that has a negative corrosion potential and is unable to passivate, or self-protect, while deployed in the well. The component is adapted to disintegrate to form substantially no debris in response to the firing of the perforating system.
