    摘要： An apparatus for reducing the post-detonation pressure of a perforating gun, the apparatus including a perforating gun carrying at least one explosive charge, wherein when the explosive charge is detonated the explosive charge produces a pressurized detonation gas, and a mechanism for reducing the pressure of the detonation gas proximate the perforating gun. The detonation gas pressure is desirably reduced in a time frame sufficient to create a dynamic underbalance condition to facilitate a surge flow of fluid from a reservoir into a wellbore. The pressure reduction mechanism may include singularly or in combination a heat sink to reduce the temperature of the detonation gas, a reactant to recombine with the reactant gas and reduce the molar density of the detonation gas, and a physical compression mechanism to utilize the waste energy of the detonation gas to create work, simultaneously reducing the temperature of the gas and the molar density of the detonation gas.

    摘要： A perforating gun and method of manufacture is provided for downhole perforation operations in a wellbore. The perforating gun includes tubular components fabricated from a multi-layer metallic/intermetallic laminate material. For example, the perforating gun may include a tubular gun carrier and/or loading tube fabricated from a multi-layers of two different metals (e.g., iron and aluminum) bonded together to form an intermetallic laminate.

    摘要： A tool for use in a wellbore has an activation assembly, which has a support structure and a reactive layer on the support structure. The reactive layer is formed of a pyrotechnic material. The activation assembly also includes an electrically conductive protective layer covering the reactive layer to protect the reactive layer from electrical discharge. The tool further includes a component to be activated by the activation assembly.
