    • 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.
    • 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。

    • A gun system in one arrangement includes a first carrier including a detonating cord and a second carrier including a detonating cord. An adapter couples the first and second carriers, with the adapter including an explosive coupled to the detonating cord of one of the first and second carriers. The explosive is positioned in a reduced housing portion of the adapter. The reduced housing portion of the adapter has a first outer diameter less than an inner diameter of the first carrier to provide a predetermined annular space between the reduced adapter portion and the inner diameter of the first carrier. At least one of the detonating cords in the first and second carriers is attached to a retainer element, and the retainer element is placed in close proximity to the explosive to maintain an axial position of the detonating cord to reduce separation between the detonating cord and the explosive. In addition, the explosive is placed some axial distance away from sensitive elements in the adapter, such as sealing elements and connector elements, to protect the sensitive elements from detonation of the explosive.
    • 一种装置中的枪系统包括包括引爆绳的第一载体和包括引爆绳的第二载体。 适配器将第一和第二载体连接,适配器包括联接到第一和第二载体之一的引爆绳的爆炸物。 炸药定位在适配器的减小的壳体部分中。 适配器的减小的壳体部分具有小于第一载体的内径的第一外径,以在减小的适配器部分和第一载体的内径之间提供预定的环形空间。 第一和第二托架中的至少一个引爆绳附接到保持器元件,并且保持器元件被放置在紧邻炸药的位置,以保持引爆绳的轴向位置,以减少引爆绳和 爆炸性 此外,炸药被放置在适配器中的敏感元件(例如密封元件和连接器元件)的一些轴向距离处,以保护敏感元件免于爆炸物的爆炸。
