A perforating gun train for perforating two or more zones of interest includes two or more gun sets made up of guns, one or more activators, and other associated equipment. An illustrative apparatus may include a first perforating gun; an activator responsive to the firing of the first perforating gun and a fuse element detonated by the activator; and a second perforating gun that is fired by the fuse element. An illustrative method for perforating a subterranean formation may include forming a perforating gun train using at least a first perforating gun and a second perforating gun; and energetically coupling the first perforating gun and the second perforating gun with an activator.
Un train de perforateurs pour perforer deux ou plusieurs sites d'intérêt comprend au moins deux jeux de perforateurs constitués de perforateurs, d'un ou de plusieurs activateurs, et du matériel associé. Un dispositif donné à titre illustratif peut comprendre un premier perforateur ; un activateur réagissant à la mise à feu du premier perforateur et un fusible détoné par l'activateur. Ledit dispositif peut comprendre en outre un second perforateur mis à feu par le fusible. Un procédé, donné à titre illustratif, de perforation d'une formation souterraine, peut comprendre les étapes consistant à : former un train de perforateurs en utilisant au moins un premier perforateur et un second perforateur ; et réaliser un couplage énergétique entre le premier perforateur, le second perforateur et un activateur.
