Title (EN) MONITORING OF DOWNHOLE PARAMETERS AND TOOLS UTILIZING FIBER OPTICS
(FR) SURVEILLANCE DE PARAMETRES ET D'OUTILS DE FOND DE PUITS AU MOYEN DE FIBRES OPTIQUES
Abstract:
(EN) The present invention provides systems utilizing fiber optics for monitoring downhole parameters and the operation and conditions of downhole tools. In one system fiber optics sensors are placed in the wellbore to make distributed measurements for determining the fluid parameters including temperature, pressure, fluid flow, fluid constituents and chemical properties. Optical spectrometric sensors are employed for monitoring chemical properties in the wellbore and at the surface for chemical injection systems. Fiber optic sensors are utilized to determine formation properties including resistivity and acoustic properties compensated for temperature effects. Fiber optic sensors are used to monitor the operation and condition of downhole devices including electrical submersible pumps and flow control devices. In one embodiment, a common fluid line is used to monitor downhole parameters and to operate hydraulically-operated devices. Fiber optic sensors are also deployed to monitor the physical condition of power lines supplying high electric power to downhole equipment. A light cell disposed downhole is used to generate electric power in the wellbore, which is used to charge batteries.
(FR) L'invention concerne des systèmes utilisant des fibres optiques pour surveiller des paramètres de fond de puits, le fonctionnement et les états des outils de fond de puits. Dans un système, des capteurs à fibres optiques sont placés dans le forage pour la réalisation de mesures réparties en vue de la détermination des paramètres relatif au fluide, tels que la température, la pression, l'écoulement, les constituants et les propriétés chimiques du fluide. Des capteurs spectrométriques optiques sont utilisés pour la surveillance des propriétés chimiques dans le forage et à la surface pour des systèmes d'injection de produits chimiques. Des capteurs à fibres optiques sont utilisés pour déterminer les propriétés de formation, telles que la résistance et les propriétés acoustiques maintenues constantes en fonction des effets de température. Les capteurs à fibres optiques sont utilisés pour surveiller le fonctionnement et l'état des dispositifs de fond de puits comprenant des pompes électriques immergées et des dispositifs de régulation de débit. Dans un mode de réalisation, une ligne commune de fluide est utilisée pour surveiller les paramètres de fond de puits et pour faire fonctionner les dispositifs à commande hydraulique. Les capteurs à fibres optiques sont également utilisés pour surveiller l'état physique des lignes d'alimentation fournissant une puissante énergie électrique à l'équipement de fond de puits. Une cellule de lumière placée au fond du puits permet de générer dans le forage de l'énergie électrique servant à recharger les batteries.
