    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: The invention relates to an igniter (8) for seismic prospection or for mining applications or for use in the crude oil and natural gas industries, comprising a detonator (7) in which an explosive material, an igniting element and internal wires (4) for initiating the igniting element are arranged, wherein the internal wires (4) lead into a plug (1, 2) which is arranged at one end of the detonator (7). In order for the user of the igniter to be able to introduce external wires (6) into the plug (1, 2) without having to strip said wires of insulation beforehand, and, in the plug (1, 2), for the internal wires (4) to be electrically connected to the external wires (6), without the external wires (6) requiring any plug and socket connector or mating part of a plug and socket connector, according to the invention, the plug is designed as a multifunctional plug (1, 2).

    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).
