摘要： A carrier for containing explosives (e.g., shaped charges) includes a housing having a plurality of recesses, each recess having a periphery and a side surface extending around the periphery. The side surface is shaped to a geometry to reduce or control reflection of compression waves generated in response to an explosive jet (e.g., a perforating jet) created due to detonation of an explosive. The side surface may be slanted from a bottom surface of the recess, or a predetermined profile may be formed in the side surface to scatter or direct compression waves. One or more shock absorbing inserts may also be placed in recesses formed by the inserts, or the recesses may be capped to trap air so that compression waves generated in the recesses are significantly reduced as compared to compression waves generated in well fluids.

摘要翻译：用于容纳炸药（例如，成形装料）的载体包括具有多个凹部的壳体，每个凹部具有周边和围绕周边延伸的侧面。侧表面被成形为几何形状以减少或控制响应于由于爆炸物的爆炸而产生的爆炸射流（例如，射孔射流）而产生的压缩波的反射。侧表面可以从凹部的底表面倾斜，或者可以在侧表面中形成预定的轮廓以散射或引导压缩波。一个或多个减震插入件也可以放置在由插入件形成的凹槽中，或者凹部可以被盖住以捕获空气，使得在凹槽中产生的压缩波与在井流体中产生的压缩波相比显着降低。

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. The adsorptive material is placed inside a container. A temperature-activated mechanism is used to open the container. The temperature-activated mechanism includes an element formed of a shape memory metal or plural layers with different coefficients of thermal expansion, such as a bi-metallic strip.

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.
