Abstract

Une vanne d'arrêt se raccorde à un train de tiges de forage pour ouvrir et fermer au moins un passage intérieur du train de tiges de forage. La vanne d'arrêt comprend une vanne annulaire portée dans un passage annulaire et qui fonctionne entre une position ouverte et une position fermée, en réponse à la pression des fluides qui s'exerce de la surface vers le bas à travers le passage annulaire. La vanne d'arrêt comprend aussi une vanne intérieure portée dans un passage intérieur du train de tiges de forage. Cette vanne intérieure est une vanne à deux voies, actionnée pour fonctionner entre une position ouverte et une position fermée, au moyen d'impulsions de pression exercées de la surface à travers le passage intérieur. La vanne est utilisable à l'intérieur d'un tube spiralé.
