Title
(EN) WELL BORE SENSING
(FR) CAPTAGE DE PUITS
Abstract
(EN)
A sensor system for use in a well bore includes a metal-clad fibre-optic cable, the fibre optic cable include one or more Bragg gratings, and each Bragg grating is configured such that a value or change in a physical parameter to be measured results in a measurable value or change in the Bragg grating. The sensor system is included in a tool moveable through a drill string. The Bragg gratings are subjected to a strain related to the well bore's pressure, such that the pressure can be determined from the characteristics of the Bragg grating.
(FR)
La présente invention décrit un système de capteur destiné à être utilisé dans un puits et qui comprend un câble de fibre optique à revêtement métallique, lequel contient un ou plusieurs réseaux de Bragg. Chaque réseau de Bragg est configuré de sorte qu'une valeur ou une modification d'un paramètre physique à mesurer entraîne une valeur ou un changement mesurable dans le réseau de Bragg. Le système de capteur est intégré dans un outil amovible dans une chaîne de percement. Les réseaux de Bragg sont soumis à une tension relative à la pression du puits, de telle sorte que la pression puisse être déterminée à partir des caractéristiques du réseau de Bragg.
