摘要： A firing head assembly is described. The firing head assembly includes a tubular housing, upper piston and lower pistons, and a compressible member arranged within a lumen of the tubular housing and positioned between the upper and lower pistons. According to an aspect, the assembly includes a safety assembly that includes a sleeve having a zigzag shaped slot therein. The safety assembly may include a key that radially extends from a surface of one of the pistons, through the zigzag shaped slot. The distance between the upper and lower pistons may be adjusted by adjusting a pressure inside the tubular housing and a second pressure outside the tubular housing. The upper and lower pistons may function to operatively adjust the arrangement of the key within the zigzag shaped slot to activate the firing head assembly to either trigger an explosive reaction or to not trigger the explosive reaction.

摘要： A non-axisymmetric shaped charge including a casing, such as a non-axisymmetric shaped casing, and a liner housed therein, is generally described in which the casing includes multiple initiation points extending in a planar arrangement along an external surface of the casing. The non-axisymmetric shaped charge may include a plurality of guiding members positioned on the external surface. The non-axisymmetric shaped charge is capable of creating sufficient ballistic energy to uniformly collapse the liner.

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： According to an aspect a bulkhead assembly is provided having particular application with a downhole tool, in particular for oil well drilling applications. The bulkhead assembly includes a bulkhead body and an electrical contact component disposed within the bulkhead body, wherein at least a portion of the electrical contact component is configured to pivot about its own axis, without compromising its ability to provide a pressure and fluid barrier. In an embodiment, a ground apparatus is provided to provide an electrical connection for at least one ground wire. The ground apparatus may be positionable on the bulkhead body of the bulkhead assembly. In an aspect, a downhole tool including the bulkhead assembly and ground apparatus is also generally described.

摘要： An igniter for seismic prospection or for mining applications or for use in the crude oil and natural gas industries is described, including a detonator in which an explosive material, an igniting element and internal wires for initiating the igniting element are arranged, wherein the internal wires lead into a plug which is arranged at one end of the detonator. In order for the user of the igniter to be able to introduce external wires into the plug without having to strip the wires of insulation beforehand, and, in the plug, for the internal wires to be electrically connected to the external wires, without the external wires requiring any plug and socket connector or mating part of a plug and socket connector, the plug is designed as a multifunctional plug.
