摘　　要：考虑到液体驱油时粘性指进可能造成原油回采严重减少，利用图像采集系统对多孔介质中由粘性指进不稳定性导致的指进花样进行显示，测算其分维指数并研究聚合物浓度与分维的关系。In view of the fact that viscous fingering can be a serious problem that leads to poor recovery of the hydrocarbon when displacing viscous oil by a more mobile fluid, the pattern formed by the viscous fingering instability in a porous medium was visualized by means of the imaging system, then the fractal dimension of viscous fingering patterns was measured and the dependence of fractal dimension on concentration of polymer was investigated.
