摘要
本文介绍了多孔介质中粘性指进现象的研究进展,景响粘性指进过程的因素很多,主要受流体与介质的润湿性及驱替液与被驱替液的粘度的影响。本文还讨论了利用计算机模拟研究多孔介质内流体流动及分形特性,粘性指进的分维在1.70左右。
The present paper reviews the recent developments in viscous fingeringin porou,media.The process of a low viscous fluid to displace a more viscous fluid inporous media is very complicated.To understand its nature,experimental researches andtheoretical analyses have been made.Computer modelling based on DLA is also used tosimulate its fractal property.It is found that its fractal dimension is around 1.70.
