摘　　要：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 on a model simulating the viscous fingering phenomenon that occur in oil recovery processes is described. The new model has water injection and oil exit pore. The adopted experimental conditions basically conform oil recovery conditions. In this paper, Keeping discharge rate (S) as the targer function, studies have been carried out on effects of the oil exit pore number (N) and the radius of pore pitch(R) on the viscous fingering phenomenon. Conclusions are f under experimental conditions, S increases as N, S decreases as R increases. Above results have a significance in studies on the mechanism of polymer flooding and improvement of flooding efficiency.
