초록

A perforating system that transfers a detonation wave between adjacent perforating guns by converting shockwave energy to electrical energy. An explosive is provided on an end of a detonating cord that is coupled to shaped charges, so that a detonation wave traveling in the detonation cord will initiate detonation in the shaped charges and then in the high explosive. The explosive is disposed adjacent a pair of members that are energized so that a magnetic field is formed between the members. When the explosive detonates, the resulting shock wave pushes ...
