为了研究多孔介质中粘性指进现象的发生和发展机理,基于随机理论建立了多孔介质计算机仿真模型。运用分形生长的理论在新建模型中进行粘性指进的模拟研究。分析了流体粘度差和非物质性对粘性指进的影响,讨论了驱替速度与粘性指进前缘分形维数之间的关系。
In order to study the occurrence and development mechanism of viscous fingering in porous media, a computer simulation model of porous media was established based on stochastic theory. Using the theory of fractal growth in the new model for viscosity indexing simulation study. The influence of fluid viscosity difference and non-materiality on viscous fingering is analyzed. The relationship between displacement speed and viscous fingering leading edge fractal dimension is discussed.
