Abstract

L’invention concerne un système de détection à multiples fibres optiques et un procédé de détection de température répartie et d’au moins une autre propriété dans un puits comprenant les étapes consistant à interconnecter un commutateur optique à une fibre optique qui s’étend le long d’un forage dans un puits ; mettre en fonctionnement le commutateur optique pour connecter optiquement la fibre optique à un système de mesure interférométrique ; et mettre en fonctionnement le commutateur optique pour connecter optiquement la fibre optique à un système de mesure de température répartie. Un autre procédé comprend les étapes consistant à installer une fibre optique le long d’un forage dans le puits, la fibre optique étant un premier capteur de température répartie, l’étape d’installation comprenant l’installation d’une longueur importante de la fibre optique à proximité d’un second capteur qui détecte la propriété du puits ; et étalonner le second capteur au moyen d’une température détectée par le premier capteur dans la longueur importante de la fibre optique.
