Title (EN) TUBING CONVEYED PERFORATING SYSTEM WITH SAFETY FEATURE
(FR) SYSTÈME DE PERFORATION TRANSPORTÉ PAR TUBULURE AVEC FONCTION DE SÉCURITÉ
Abstract:
(EN) A tubing conveying perforating system with a firing head is provided, and a method for using the same is provided. The firing head (20) includes a firing pin (24) and a percussion initiator (26). The firing pin is configured to degrade over a predetermined period of time from an initial state to a degraded state, and in the degraded state the firing head is inoperable..
(FR) La présente invention concerne un système de perforation transporté par tubulure doté d'une tête d'amorce ainsi que son procédé d'utilisation. La tête d'amorce (20) comprend une broche d'amorce (24) et un initiateur de percussion (26). La broche d'amorce est conçue pour se dégrader sur une période de temps prédéfinie d'un état initial à un état dégradé et la tête d'amorce est inutilisable dans l'état dégradé.
