Title (EN) AUTONOMOUS ANNULAR PRESSURE CONTROL ASSEMBLY FOR PERFORATION EVENT
(FR) ENSEMBLE DE RÉGULATION DE PRESSION ANNULAIRE AUTONOME POUR ÉVÉNEMENT DE PERFORATION
Abstract:
(EN) A system and method of controlling a dynamic time-pressure profile associated with a perforation event that includes extending a perforation assembly within a casing string; firing a perforation gun of the perforation assembly; measuring, using a sensor of the perforation assembly, pressure within the casing string, wherein the measured pressure forms the dynamic time-pressure profile; identifying a first measured pressure within the dynamic time-pressure profile; identifying, using a controller of the perforation assembly, a first difference between the first measured pressure and a first reference pressure; and adjusting, using a first pressure generator of the perforation assembly, the pressure in response to the first difference to control the dynamic time-pressure profile; wherein the sensor, the controller, and the first pressure generator provide a feedback control loop.
(FR) L'invention concerne un système et un procédé pour commander un profil temps-pression dynamique associé à un événement de perforation, lequel procédé consistant à déployer un ensemble de perforation dans une colonne de tubage ; à déclencher un perforateur de l'ensemble de perforation ; à mesurer, à l'aide d'un capteur de l'ensemble de perforation, une pression dans la colonne de tubage, la pression mesurée formant le profil temps-pression dynamique ; à identifier une première pression mesurée dans le profil temps-pression dynamique ; à identifier, à l'aide d'un dispositif de commande de l'ensemble de perforation, une première différence entre la première pression mesurée et une première pression de référence ; et à régler, à l'aide d'un premier générateur de pression de l'ensemble de perforation, la pression en réponse à la première différence pour commander le profil temps-pression dynamique ; le capteur, le dispositif de commande et le premier générateur de pression fournissant une boucle de commande de rétroaction.
