Title
(EN) DETERMINING FLUID PROPERTIES
(FR) DÉTERMINATION DE PROPRIÉTÉS DE FLUIDE
Abstract
(EN) Techniques for measuring liquid properties include circulating a mixed oil-water liquid flow through a fluid flow circuit; polarizing the mixed oil-water liquid flow with a pre-polarizing magnet to an initial polarization; circulating the polarized mixed oil-water liquid flow to an EFNMR detector that includes a radio-frequency (RF) coil and a surrounding electromagnet; further polarizing the polarized mixed oil-water liquid flow with the surrounding electromagnet; measuring fluid induction decay (FID) values of the additionally polarized mixed oil-water liquid flow with the EFNMR detector; transforming the measured FID values to an effective adiabatic transition from the Earth's field to the polarizing field; determining a velocity of the oil in the mixed oil-water liquid flow and a velocity of the water in the mixed oil-water liquid flow based on differences in NMR signal relaxation properties of the transformed FID values; and determining an oil content and a water content of the mixed oil-water liquid flow from the transformed FID values.
(FR) Des techniques de mesure de propriétés liquides comprennent la circulation d'un écoulement de liquide huile-eau mélangé à travers un circuit d'écoulement de fluide ; la polarisation du flux de liquide huile-eau mélangé avec un aimant de pré-polarisation selon une polarisation initiale ; la circulation du flux de liquide d'huile-eau mélangé polarisé vers un détecteur EFNMR qui comprend une bobine radiofréquence (RF) et un électroaimant environnant ; la polarisation supplémentaire du flux de liquide huile-eau mélangé polarisé avec l'électroaimant environnant ; la mesure des valeurs de décroissance de l'induction de fluide (FID) de l'écoulement de liquide huile-eau mélangé à polarisation supplémentaire avec le détecteur EFNMR ; la transformation des valeurs FID mesurées en une transition adiabatique efficace du champ de la terre au champ de polarisation ; la détermination d'une vitesse de l'huile dans le flux de liquide huile-eau mélangé et d'une vitesse de l'eau dans le flux de liquide huile-eau mélangé sur la base de différences de propriétés de relaxation de signal NMR des valeurs FID transformées ; et la détermination d'une teneur en huile et d'une teneur en eau du flux de liquide huile-eau mélangé à partir des valeurs FID transformées.
