Title
(EN) SUBTERRANEAN WELL PRESSURE AND TEMPERATURE MEASUREMENT
(FR) MESURE DE LA PRESSION ET DE LA TEMPERATURE D'UN PUIS SOUTERRAIN
Abstract
(EN)
A well pressure and temperature measurement system and method are provided. In a described embodiment, a sensor system (12) includes multiple strain sensors attached to a structure which changes dimensionally in response to well pressure and temperature changes. The strain sensors may be fiber optic sensors. The structure may be tubular and the strain sensors may detect axial and hoop strains in the structure.
(FR)
L'invention a trait à un système et à un procédé de mesure de la pression et de la température d'un puits. Dans un mode de réalisation décrit, un système de capteurs (12) comprend de multiples capteurs de déformation, qui sont fixés sur une structure dont les dimensions changent en réponse à des modifications de la pression et de la température du puits. Les capteurs de déformation peuvent se présenter sous la forme de capteurs à fibres optiques. La structure peut être tubulaire, et les capteurs de déformation peuvent détecter les déformations axiales et transversales se produisant dans la structure.
