This paper describes the application of 1H magnetic resonance imaging (MRI) to the measurement of fluid viscosity and rock core plug permeability during two phase miscible displacements in certain rock types. The core plug permeability was determined by monitoring glycerol solutions displacing D2O. Simple physical principles were used to calculate the core permeability from the measured displacement angle for a set of Lochaline sandstone core plugs. In a further experiment the viscosity of polyacrylamide solution 1500 ppm was determined in the core plug. The permeability and viscosity results compared well to conventional core analysis methods.
本文描述了1H磁共振成像（MRI）在测量特定岩石类型中两相混相驱替过程中的流体粘度和岩心柱塞渗透率方面的应用。通过监测甘油溶液驱替重水来测定岩心柱塞渗透率。利用简单的物理原理，根据一组洛查林砂岩岩心柱塞的测量驱替角来计算岩心渗透率。在进一步的实验中，测定了岩心柱塞中1500 ppm聚丙烯酰胺溶液的粘度。渗透率和粘度结果与传统岩心分析方法的结果吻合良好。
