    摘要: The invention relates to a method for completing a borehole (1, 2) prior to the start of production, wherein after making the borehole (1, 2) the borehole wall (3) is anchored in a sealed manner with a conveying tube (4) and/or casing tube, and the borehole wall (3) is perforated with perforation units (5) at desired points. To complete a borehole without the use of cemented conveying tubes and/or casing tubes, it is proposed that the conveying tube (3) and/or casing tube be provided on its outer surface with a swellable sealing jacket (6), wherein the sealing jacket (6) swells after activation and anchors the annular gap between the conveying tube (4) and/or casing tube and the borehole wall (3) in a sealed manner and simultaneously centres the conveying tube (4) and/or casing tube in the borehole (1, 2).

    摘要: The invention relates to a perforating gun having an outer gun barrel, inside of which an inner barrel is coaxially arranged, carrying perforators that can be ignited by means of a detonating cord leading through the gun barrel and, after ignition, pierce the gun barrel in order to form penetration holes, wherein means are provided for automatically closing the penetration holes after the blast, said means being a swellable medium. In order to ensure that the swellable medium requires little space in the perforating gun and can be easily integrated into the perforating gun, according to the invention the swellable medium is disposed in a laminary manner inside the perforating gun.

    摘要: An apparatus for storing and/or shipping explosive components, such as shaped charges, is generally described. In an embodiment, the apparatus includes a shielding assembly. The shielding assembly may include a shielding panel having a body made of metal foam and an aperture formed within the body. In an embodiment, the body is sandwiched between an upper and a lower layer. The shielding panel is configured to receive a shaped charge. Thus, the apparatus is capable of at least preventing and/or limiting ballistic transfer in the event of detonation of a shaped charge.
