摘要： A shaped charge pipe cutter is constructed with the cutter explosive material packed intimately around an axially elongated void space that is continued through a heavy wall boss portion of the upper thrust disc. The boss wall is continued to within a critical initiation distance of a half-cuter junction plane. An explosive detonator is positioned along the void space axis proximate of the outer plane of the upper thrust disc. Geometric configurations of the charge thrust disc and end-plate concentrate the detonation energy at the critical initiation zone.

摘要： A gas generator (10) is provided, comprising an initiator (48) including an initiator charge, a gas generant insert (52) spaced apart from the initiator (48), and a fluid-impermeable blast director (42) interposed between the initiator (48) and the gas generant insert (52). The blast director (42) provides a barrier between the gas generant insert (52) and a blast resulting from ignition of the initiator charge when the initiator charge is ignited. The blast director (42), when used with particular gas generant configurations, reduces the effects of the initiator blast and reduces the amount of gas generant exposed to the blast, enabling the structural integrity of the gas generant (52) to be maintained.

摘要： An explosive diode transfer system is interconnected between adjacent perforating guns of a modular perforating apparatus. The explosive diode transfer system includes a downwardly directed shaped charge, a booster, and a multi-density barrier interposed between the shaped charge and the booster. The multi-density barrier includes a first metal layer and a second metal layer spaced from the first metal layer thereby defining a sealed air-space between the first and second metal layers. The first metal layer, air space, second metal layer combination represents a plurality of different density barriers or layers which are collectively designed to prevent a first detonation wave, propagating from the booster to the shaped charge, from propagating therethrough, but nevertheless to allow a jet, propagating from the shaped charge to the booster, to propagate therethrough. The multi-density character of the barrier and the air space reflect and therefore completely attenuate the first detonation wave as it propagates from the booster to the shaped charge, but does not significantly attenuate the jet propagating from the shaped charge to the booster. Therefore, the explosive diode transfer system functions like a diode, allowing propagation in one direction, but not allowing propagation in the opposite direction. Consequently, the multi-density barrier of the explosive diode transfer system prevents a back fired detonation wave originating from a lower oriented perforating gun from detonating a higher oriented perforating gun in the modular perforating apparatus.

摘要： Blasting devices, each comprising an explosive substance, a deflector, and a casing containing an incompressible fluid, the explosive substance, and the deflector are inserted into respective holes bored in a rock or the like at spaced apart positions, a tamper being thereafter stuffed in each hole, and the explosive substances in the holes are detonated simultaneously. A shock wave or blast wave is thus created in the incompressible fluid in each hole, and is deflected by the deflector in a direction along which the rock or the like is to be fractured. An improved construction of the blasting device for practicing the method is also provided.
