Title (EN) AUTOMATED CHOKE CONTROL APPARATUS AND METHODS
(FR) APPAREIL ET PROCÉDÉS DE COMMANDE D'ÉTRANGLEUR AUTOMATISÉE
Abstract:
(EN) Automated choke control apparatus and methods are disclosed herein. An apparatus for automatically controlling a choke valve comprises a controller. The controller is to control a choke position of the choke valve via a first control loop in response to selection of a first one of a plurality of operation modes being detected. The controller is further to control a wellhead pressure of a wellhead via a second control loop in response to selection of a second one of the plurality of operation modes being detected, the wellhead being operatively coupled to the choke valve.
(FR) La présente invention concerne un appareil et des procédés de commande d'étrangleur automatisée. Un appareil pour commander automatiquement un étrangleur comprend un dispositif de commande. Le dispositif de commande est destiné à commander une position d'étrangleur de la soupape d'étranglement par l'intermédiaire d'une première boucle de commande en réponse à la sélection d'un premier mode parmi une pluralité de modes de fonctionnement détectés. Le dispositif de commande est en outre destiné à commander une pression de tête de puits d'une tête de puits par l'intermédiaire d'une deuxième boucle de commande en réponse à la sélection d'un deuxième mode parmi la pluralité de modes de fonctionnement détectés, la tête de puits étant fonctionnellement raccordée à l'étrangleur.
