Abstract

La présente invention a trait à une technique qui commande la mise en marche d'un matériel d'extraction dans un puits de forage. La technique utilise une membrane de pression de rupture dans une voie de passage de fluide de commande utilisé pour mettre en marche le matériel d'extraction. Un matériau énergétique est monté à proximité du disque de rupture, et ce matériau énergétique peut être éclaté de façon sélective. L'énergie résultante est suffisante pour commencer la rupture de la membrane de pressurisation de rupture qui permet l'écoulement du fluide de commande vers le matériel d'extraction.
