    Measurement on Scale of Wettability of Porous Media with NMR Methods

    • 摘要: 核磁共振测量技术已能够快速而无损地获得孔隙介质的物性信息, 但对于颗粒表面润湿性的测量还处于定性到半定量的水平.采用毛细管法和玻璃板法对经不同浓度二甲基二氯硅烷溶液处理的玻璃表面润湿性测量, 然后对核磁共振方法测量的孔隙介质润湿性结果进行标定, 进而得到孔隙介质润湿性系列的刻度特征.实验表明, 对于玻璃颗粒孔隙介质, 核磁共振测量的结果在作为表面处理剂的二甲基二氯硅烷溶液浓度0 %~ 0.7%变化范围内才与孔隙介质润湿性的变化有着明确的对应关系.在此范围之外, 对应的驰豫时间的变化虽然较大, 但其对于润湿性的刻度已没有明确的作用.
