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。 CT scanning technology not only can reconstruct the microscopic remaining oil distribution images of different displacement fluid at different flooding times, but also calculate the porosity and oil saturation parameters of core by calculating the X-ray attenuation coefficient into CT value, Of the heterogeneity and the micro-residual oil at different flooding times during each flooding process. Analyzes suggest that there is an amount of conversion of experimental cores between the microscopic remaining oil types at different stages of flooding.
