Title (EN) EFP DETONATING CORD
(FR) CORDEAU DÉTONANT DE PROJECTILE FORMÉ PAR EXPLOSION
Abstract:
(EN) A perforating tool (100) includes an encapsulated shaped charge (10) that has a bulkhead (26) with a reduced wall thickness section (34), a plate (55) having a shallow recess, and a detonating cord (50) having an energetic core (52). The energetic core forms the plate into an explosively formed perforator when detonated. The plate is positioned to direct the explosively formed perforator into the reduced wall thickness section.
(FR) Cette invention concerne un outil de perforation (100), comprenant une charge creuse encapsulée (10) qui possède une cloison (26) avec une section à épaisseur de paroi réduite (34), une plaque (55) présentant un évidement peu profond, et un cordeau détonant (50) possédant un noyau énergétique (52). Le noyau énergétique forme la plaque en un projectile formé par explosion lors de la détonation. La plaque est positionnée pour diriger le projectile formé par explosion dans la section à épaisseur de paroi réduite.
