CA 2584531

Methods and apparatus for detecting an operation of a downhole tool using an optical sensing system are disclosed. In an embodiment, a flow control device has an inner tubular member moveable relative to an outer tubular member and a thermally responsive chamber capable of a change in temperature during a movement between the inner tubular member and the outer tubular member. Detecting the change in temperature in the thermally responsive chamber with an optical sensing system provides real time knowledge of the position of the flow control device. In another embodiment, a flow control device comprises an inner tubular member moveable relative to an outer tubular member that produces an acoustic signal during a movement between the inner tubular member and the outer tubular member. Detecting the acoustic signal with an optical sensor provides real time knowledge of the position of the flow control device.

Des méthodes et des appareils sont décrits aux fins de détection de l'opération d'un outil de fond à l'aide d'un système de détection optique. Dans l'une des configurations, un dispositif de contrôle de flux est muni d'un élément tubulaire interne, mobile par rapport à un élément tubulaire externe, de même que d'une chambre thermosensible qui change de température pendant un mouvement entre l'élément tubulaire interne et l'élément tubulaire externe. La détection d'un changement de température à l'intérieur de la chambre thermosensible au moyen d'un système de détection optique fournit des données en temps réel sur la position du dispositif de contrôle de flux. Une autre configuration propose un dispositif de contrôle de flux muni d'un élément tubulaire interne, mobile par rapport à un élément tubulaire externe, qui produit un signal acoustique pendant un mouvement entre l'élément tubulaire interne et l'élément tubulaire externe. La détection d'un signal acoustique à l'aide d'un capteur optique fournit des données en temps réel sur la position du dispositif de contrôle de flux.
