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： 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, the swellable medium is disposed in a laminary manner inside the perforating gun.

摘要： A packaging for hollow charges for use in blasting applications in boreholes retains fragments in the event of unintentional ignition of the hollow charges. The packaging withstands and dissipates the pressure generated. It is proposed that the hollow charges are embedded in a solid material which captures the fragments, the solid material has pressure relief openings through which the pressure generated during a detonation of the hollow charges can escape, the solid material is covered with shock-absorbing material on the top side and on the base side of the packaging, the hollow charges are packed in pairs such that there are always two hollow charges situated with their openings facing each other, the axes of symmetry of the hollow charges are arranged in a plane perpendicular to the top side and base side, and the solid material is inserted with the hollow charges and the shock-absorbing material into a cage.

摘要： The invention relates to a packing having a top side, a base side and face sides for hollow charges for use in blasting applications in boreholes. In order that fragments are retained in the packing in the event of an unintentional ignition of the hollow charges, the packing withstands the pressure which is generated and permits a dissipation of pressure, it is proposed according to the invention that a) the hollow charges are embedded in a solid material which captures the fragments generated during a detonation of the hollow charges, b) the solid material has pressure relief openings through which the pressure wave of the gas volume generated during a detonation of the hollow charges can escape, c) the solid material is covered with shock-absorbing material on the top side and on the base side of the packing, d) the hollow charges are packed in pairs such that there are always two hollow charges situated opposite the openings, e) the axes of symmetry of the hollow charges are arranged in a plane perpendicular to the top side and base side, and f) the solid material is inserted with the hollow charges and the shock-absorbing material into a cage, preferably a bar-grate-type cage.
