    摘要： A perforating system having a perforating gun with a tubular gun housing defining an inner volume and extending in an axial direction. A shaped charge is held in a loading tube. The loading tube is located in the gun housing. The loading tube extends along the axial direction. The shaped charge faces in a firing direction substantially perpendicular to the axial direction. A portion of the gun housing adjacent to the shaped charge in the firing direction is a perforating portion for removal upon firing of the shaped charge. An eccentralizer member extends from the perforating gun in a second direction that is substantially opposite and parallel with the firing direction. A first retainer part extends from an outer surface of the gun housing adjacent to the perforating portion. A second retainer part extends from the outside of the gun housing adjacent to the perforating portion.

    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： The present invention provides an apparatus for use in perforating a well having a plurality of explosive charges. Each explosive charge is adapted to generate a perforation tunnel in the formation adjacent to the well. In one embodiment, explosive charges are oriented to create perforation tunnels that converge at a location within the formation in order to create a fracture initiation plane capable of mitigating or avoiding hydraulic fracturing complications.

    摘要： A shaped charge includes: a charge case; an explosive disposed inside the charge case; and a liner for retaining the explosive in the charge case, wherein the liner is fabricated from a material soluble with a selected dissolving fluid (e.g., an acid, an acid matrix, an injection fluid, a completion fluid, and/or a wellbore fluid). A method for perforating in a well includes the steps of: disposing a perforating gun in the well, wherein the perforating gun comprises a shaped charge having a charge case, an explosive disposed inside the charge case, and a liner for retaining the explosive in the charge case, wherein the liner is fabricated from a material soluble with a selected dissolving fluid; detonating the shaped charge to form a perforation tunnel in a formation zone; and exposing the material comprising the liner to the selected dissolving fluid.
