| 摘 要： | 利用核磁共振成像技术，观察玻璃珠填装管状模型与河砂填装管状模型内油的运移过程，测量并分析油运移路径形态特征和内部含油饱和度。原始油柱内油饱和度可达83％；路径形成油沿路径运移时，油在路径内的饱和度为40％～50％；运移完成后，在没有油继续供给的条件下，原有路径收缩，宽度减小，路径内的油呈不连续状态，残余油饱和度降为20％～35％。实验装置中孔隙介质的颗粒成分对路径内的油饱和度有一定影响。图2表1参16

| Abstract: | NMR imaging technique was applied to observe the oil migration pathways within a glass cylinder filled with water- wetting glass beads or sand grains. The oil saturations in the migration pathways at different stages are measured. It is found that the oil saturation may reach 830/00 within the initial accumulation column. The saturation is about 40%0-50%0 within the pathway when the latter is growing. The saturation is about 20%-35% within the pathway when migration finishes. The grains surface properties seem to influence the saturation within the pathway. |
