CA 2398715

A sequential hydraulic well control system provides actuator selection and operation utlizing pressure applied to hydraulic lines (A, B, C) in a sequence. In a disclosed embodiment, an actuation control device (348) of a well control system includes multiple pistons, at least one of which is included in a latch for selectively permitting and preventing displacement of another of the pistons. When one of the pistons displaces in response to pressure applied sequentially to hydraulic inputs (A, B, C) of the control device, an associated actuator (370) is placed in fluid communication with the inputs.

Un système de commande hydraulique séquentielle de puits permet la sélection et le fonctionnement du vérin au moyen d'une pression appliquée sur des conduites hydrauliques (A, B, C) en séquence. Dans un mode de réalisation de l'invention, un dispositif de commande d'actionnement (348) d'un système de commande de puits comprend plusieurs pistons dont au moins un est inclus dans un verrou, ce qui permet ou empêche sélectivement le déplacement d'un des autres pistons. Lorsqu'un des pistons se déplace en réponse à une pression appliquée séquentiellement sur des entrées hydrauliques (A, B, C) du dispositif de commande, un vérin associé (370) est mis en communication fluidique avec les entrées.
