Title (EN) CHEMICALLY-SELECTIVE IMAGER FOR IMAGING FLUID OF A SUBSURFACE FORMATION AND METHOD OF USING SAME
(FR) DISPOSITIF D'IMAGERIE CHIMIQUEMENT SÉLECTIF POUR IMAGER UN FLUIDE D'UNE FORMATION SOUTERRAINE ET SON PROCÉDÉ D'UTILISATION
Abstract:
(EN) An imager and method for imaging fluid of a subsurface formation is disclosed. The imager includes a housing having a sidewall defining a passage to receive a core sample of the subsurface formation therethrough. The housing is positioned in a downhole tool and has a fluid inlet to receive fluid from the subsurface formation into the passage. The imager also includes a permanent magnet positioned in the sidewall of the housing, a radio frequency coil positioned in the sidewall of the housing between the permanent magnet and the passage, a gradient field in the sidewall of the housing between the permanent magnet and the radio frequency coil, and a chemically-selective imager. The chemically-selective imager is operatively connected to the radio frequency coil to selectively pulse frequencies according to a pulse sequence whereby individual fluid measurements of the sample are generated.
(FR) Cette invention concerne un dispositif d'imagerie et un procédé d'imagerie d'un fluide d'une formation souterraine. Le dispositif d'imagerie comprend un boîtier présentant une paroi latérale définissant un passage pour recevoir une carotte de la formation souterraine. Le boîtier est positionné dans un outil de fond et il présente une entrée de fluide pour recevoir un fluide provenant de la formation souterraine dans le passage. Le dispositif d'imagerie comprend également un aimant permanent positionné dans la paroi latérale du boîtier, une bobine de radiofréquence positionnée dans la paroi latérale du boîtier entre l'aimant permanent et le passage, un champ de gradient dans la paroi latérale du boîtier entre l'aimant permanent et la bobine de radiofréquence, et un dispositif d'imagerie chimiquement sélectif. Le dispositif d'imagerie chimiquement sélectif est fonctionnellement relié à la bobine de radiofréquence pour pulser sélectivement des fréquences suivant une séquence d'impulsions, de sorte à générer des mesures de fluide individuelles de l'échantillon.
