Title (EN) PRESSURE MANAGEMENT SYSTEM FOR WELL CASING ANNULI
(FR) SYSTÈME DE GESTION DE PRESSION POUR ESPACE ANNULAIRE DE TUBAGE DE PUITS
Abstract:
(EN) An apparatus and method to provide monitoring of pressure outside the wellbore casing (2) of a well in which a Wireless Sensor Unit (1) is placed externally of a section of non- magnetic casing (20); an internal Sensor Energiser Unit (9) is placed inside the wellbore casing. The WSU includes one or more sensors (10) to measure the pressure and/or temperature of the surroundings and the WSU and SEU communicate using electromagnetic modulation techniques and the WSU is powered by means of power harvesting (100) from the SEU.
(FR) L'invention porte sur un appareil et sur un procédé destinés à assurer la surveillance de la pression à l'extérieur d'un tubage (2) de puits de forage dans lequel une unité de capteur sans fil (1) est disposée à l'extérieur d'une section de tubage non magnétique (20); une unité d'activation de capteur (9) interne est placée à l'intérieur du tubage de puits de forage. L'unité de capteur sans fil comprend un ou plusieurs capteurs (10) de mesure de la pression et/ou de la température de l'environnement et l'unité de capteur sans fil et l'unité d'activation de capteur communiquent à l'aide de techniques électromagnétiques de modulation. En outre, l'unité de capteur sans fil est alimentée au moyen d'une collecte d'énergie (100) à partir de l'unité d'activation de capteur.
