Abstract

L'invention concerne un système et un procédé de tir sélectif pour commander des opérations dans un ensemble train de tiges de perforateurs comprenant des perforateurs et des sous-ensembles de commutateurs reliés mécaniquement dans l'ensemble train de tiges de perforateurs. Chacun des sous-ensembles de commutation comprend en outre un élément de commutation, des liaisons d'entrée et des liaisons de sortie. Les sous-ensembles de commutation et les perforateurs communiquent entre eux par l'intermédiaire des liaisons d'entrée et de sortie. Les éléments de commutation surveillent l'état du sous-ensemble et commutent les états sur la base de conditions de déclenchement telles que des conditions environnementales, des conditions de perforateur ou des conditions d'entrée depuis la surface. L'invention porte également sur un procédé d'auto-détection pour détecter des défaillances dans un perforateur et agir sur la défaillance sans qu'il soit nécessaire de retirer l'ensemble train de tiges de perforateur du puits de forage.
