| 摘 要： | CT扫描技术不仅可以重建不同驱替液在不同驱替时刻的微观剩余油分布图像,而且通过X射线衰减系数换算成CT值,还可以计算岩心的孔隙度和含油饱和度参数,从而对实验岩心的非均质性和每一驱替过程不同驱替时刻的微观剩余油进行定量分析。分析认为实验岩心在不同驱替阶段微观剩余油类型之间存在量的转化。

| Abstract: | CT scan technology not only can rebuild the distribution images of microscopic remaining oil in different flooding stages, but also can calculate cores' porosity and oil saturation by CT value that can be converted by X-ray attenuation coefficient, thus realize quantitative characterization of the cores' inhomogeneous and microscopic remaining oil distribution in different flooding stages during the period of each flooding experiment. The conclusion from analysis can be got that these microscopic residual oil can be exchanged quantitatively in different flooding stages. |
