Abstract: The non-Newtonian effect of polymer solution was not taken into account in the sealing criteria for polymer flooding experiments in studies carried out so far and no method was presented to analyze the effects on the predicted results when a certain similarity group is neglected.New scaling criteria for polymer flood experiments are formulated in our work,with non-Newtonian effect being considered.And also,a numerical method is presented for evaluating the validity of scaling criteria and for doing sensitivity analyses,Five different approaches to satisfying the scaling criteria for application are given.

摘要： 文献[1]、[2]给出的聚合物驱油相似准则,没有考虑聚合物溶液的非牛顿特性;对预测结果的影响程度,没有专门的分析方法.本文重新建立了聚合物驱油的相似准则,并给出了对准则的正确性进行检验及敏感性分析的数值方法.针对具体应用,列出了五种不同条件下的模化方法.
