Abstract
Improving oil displacement efficiency is the focus of oilfield concern.To efficiently develop the remaining oil in the ultra-high water cut period,this study analyzed the formation mechanism and distribution state of the remaining oil.Taking the capillar-y bundle model as an example,the force analysis of the oil droplet movement was carried out,and the quantitative characterization of the microscopic oil displacement efficiency was obtained.The development countermeasures were put forward respectively from two aspects of optimizing injection and production mode and adjusting displacement parameters,which was the research on the distri-bution of remaining oil in the ultra-high water cut period.The study provides both theoretical basis and guidance for improving oil displacement efficiency.关键词
