粘性指进模型的进一步改进，新模型既有注水孔又有出油孔，实验条件基本符合采油条件。以排出率（Ｓ）为目标函数，研究了出油孔数目（Ｎ）和孔距半径（Ｒ）对粘性指进的影响。得到结论是：在该条件下，Ｓ随着Ｎ增大而增大，Ｓ随Ｒ的增大而降低。上述结果对研究聚合物驱油机理，提高驱油效率有一定意义。 Further improvement of the viscous fingering model, the new model has both water holes and oil holes, the experimental conditions are basically in line with the oil production conditions. Taking the discharge rate (S) as the objective function, the influence of the number of oil holes (N) and the pitch radius (R) on the viscosity index was studied. It is concluded that under this condition, S increases with increasing N, and S decreases with increasing R. The above results have some significance for studying the mechanism of polymer flooding and improving the flooding efficiency.
