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).

The invention relates to a packaging for a detonation cord (1) that is used especially for igniting shaped charge perforators in perforation guns utilized in the oil and natural gas industry. According to the invention, the detonation cord (1) is wound on one plane as a flat coil. Also disclosed is a method for examining whether a detonation cord (1) has faulty points. Said method is characterized in that the detonation cord (1) is subjected to an x-ray examination in the packaging before being delivered.

摘要:
The invention relates to a perforation gun comprising an external gun barrel (1) in the interior of which perforators (10) are located which can be ignited via a fuse (11) extending through the gun barrel (1) and which, after ignition, pierce the gun barrel (1) with perforation holes (13), whereby means are provided which automatically close the perforation holes (13). According to an embodiment of the invention, the means for automatically closing the perforation holes comprise cartridges including a swellable two-component foam. Said cartridges are located inside the gun barrel (1) and can be broken up by the ignited fuse (11), thereby allowing foam to escape from the cartridges, allowing it to swell and obliterate the perforation holes (13). If the means for automatically closing the perforation holes (13) comprise a sliding tube (4) that can be displaced after perforation by an adjusting device by at least the diameter of the perforation hole (13), the sliding tube (4) is located coaxially between the perforators (10) and the gun barrel (1).
