摘要
By using the deduced formula of mobile interface in capillary, it is to explain qualitatively and quantitatively the distribution of remaining oil in the process of water flooding oil in parallell connection capillaries. Capillary force is applied to Darcy law, the wetting and capillary are considered to derive the model of interface movement in the capillary, which help build remaining oil model in the capillary scale. The remaining oil model of water flooding base on capillary is built, which is not affected by surface roughening of capillary and flow pattern; this expands Poiseuille equation.
