摘　　要：常规岩心的驱替实验只能得到流体通过岩心前后端的参数指标,采用工业微焦点X-CT技术,对聚合物驱油的岩心驱替试验采用二维实验模型平面断层扫描,用CT扫描重建了驱替过程中不同时间的油、水、聚合物的分布情况。从微观的角度直观显示油水分布的不均匀性和液相前沿的指进现象以及注入聚合物段塞后,显示其有效地富集了水驱之后的剩余油。研究结果表明聚合物驱油可以提高孔隙利用系数,从而提高驱油效果。Through experiments of oil being flooding by water on conventional core models,we can only obtain parameters of the liquid at the moment prior to or after their passing through the related models.Through scanning and observing well core displacement,X-CT makes it possible that reconstruction process of oil、water and polymer displacement in different time.We can directly show heterogeneity of oil-water distributions,finger advance of fluid phase front and the oil recovery was enhanced after polymer slug was injected into the core.The result indicates polymer flooding can raise pore space utilization coefficient.It also suggests that polymer viscoelasticity has definite function.
