A downhole fluid analysis system comprises an input light signal that is directed through a fluid sample housed in a sample cell (202) . The input light signal may originate from a plurality of light sources (200) . A light signal output from the sample cell is then routed (206) to two or more spectrometers (214, 216) 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 input light can be routed directly (210) to the two or more spectrometers to be used in calibration of the system in the high temperature and noise environment downhole.

L'invention concerne un système d'analyse de fluides de fond de trou comprenant un signal lumineux d'entrée dirigé à travers un échantillon fluidique se trouvant dans une cellule d'échantillon (202). Le signal lumineux d'entrée peut provenir de plusieurs sources de lumière (200). Un signal lumineux de sortie provenant de la cellule d'échantillon est ensuite acheminé (206) vers deux spectromètres ou plus (214, 216) afin de mesurer les longueurs d'onde représentées dans le signal lumineux de sortie. La sortie des spectromètres est ensuite comparée à des valeurs connues d'hydrocarbures généralement rencontrés en fond de trou, ce qui fournit un aperçu de la composition de l'échantillon fluidique. La lumière d'entrée peut, en outre, être acheminée directement (210) vers les deux spectromètres ou plus à utiliser pour étalonner le système dans le fond de trou à environnement sonore et à température élevée.
