    摘要： Apparatus and method for cooling a component inside a tool includes a container and a plurality of heat sinks positioned in the container. The components are positioned in the container with the heat sinks for maintaining a reduced temperature inside the container. Further, an insulating layer and a reflective layer surround the heat sinks and components to reduce heat transfer. Alternatively, the container can have a hollow wall that encloses the space in which a heat sink material (such as an eutectic material) is disposed. The components to be protected are located in the container. The eutectic material includes a composition having tin and zinc. The insulating layer includes a container that stores a vacuum layer, such as a dewar flask.

    摘要： A loading tube of a perforating gun includes a plurality of mating holes, where each mating hole has a specific and predetermined contour, and a case of a shaped charge, adapted to fit within the mating hole, includes a pair of retaining lugs and a pair of shoulder lugs, which lugs are adapted to uniquely cooperate with the contour of the mating hole of the loading tube for securing the shaped charge to the loading tube. The predetermined contour of each mating hole includes a pair of slots disposed opposite one another in the mating hole, and a pair of grooves disposed opposite one another in the mating hole but offset from the pair of slots. Each pair of grooves includes a large radius groove and a small radius groove. The pair of retaining lugs of the shaped charge case are adapted to be received, respectively, in the pair of slots of the contour of the mating hole; whereas the pair of shoulder lugs are adapted to be initially received in the pair of large radius grooves of the contour of the mating hole. When the shaped charge is twisted clockwise in a circumferential direction, the retaining lugs move out of their respective slots and under a surface of the loading tube; in addition, the shoulder lugs moves out of their respective large radius grooves and into their respective small radius grooves. The shaped charge case is now firmly held within the mating hole of the loading tube. No clips, bending tabs, retaining rings, or charge retention jackets are being used to hold the shaped charge to the loading tube; therefore, when the charges detonate, there will be no debris resultant from the detonation.

    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： A hands-free connection system is provided for coupling downhole tools for use in well operations. The connection system includes two downhole tools connectable together in threaded engagement. The connection system further includes a compressible locking sleeve positioned between the coupled downhole tools for maintaining the tools in threaded engagement and in a predetermined alignment for deployment downhole.
