Title (EN) METHOD AND APPARATUS FOR CALIBRATED DOWNHOLE SPECTRAL ANALYSIS OF FLUIDS
(FR) PROCÉDÉ ET APPAREIL POUR ANALYSE SPECTRALE ÉTALONNÉE DE FOND DE TROU
Abstract: front page image
(EN)A fluid analysis system for use downhole comprises an input light signal that is directed through a fluid sample housed in a sample cell (184) . The input light signal may originate from a plurality of light sources (180) . An output light signal from the sample cell is then routed to one or more spectrometers (186) for measurement of the represented wavelengths in the output light signal. The output of the spectrometers is then compared to known values for hydrocarbons typically encountered downhole . This provides insight into the composition of the sample fluid. Additionally, the light from the light sources can be routed directly to the one or more spectrometers to be used in calibration of the system in the high temperature and noise environment downhole .
(FR)L'invention concerne un système d'analyse fluidique utilisé en fond de trou comprenant un signal lumineux d'entrée dirigé à travers un échantillon fluidique se trouvant dans une cellule d'échantillon (184). Le signal lumineux d'entrée peut provenir de plusieurs sources de lumière (180). Un signal lumineux de sortie provenant de la cellule d'échantillon est ensuite acheminé vers un ou plusieurs spectromètres (186) afin de mesurer les longueurs d'onde représentées dans le signal lumineux de sortie. La sortie des spectromètres est ensuite comparée aux valeurs connues des hydrocarbures généralement rencontrés en fond de trou, ce qui fournit un aperçu de la composition de l'échantillon fluidique. En outre, la lumière provenant des sources de lumière peut être acheminée directement vers un ou plusieurs spectromètres à utiliser pour étalonner le système dans le fond de trou à environnement sonore et température élevée.
