摘要
聚合物驱相对渗透率曲线是研究聚驱渗流机理和编制聚驱开发方案必不可少的重要基础数据,但由于聚合物溶液在多孔介质中的非牛顿流体特性,如何准确测定聚合物驱相对渗透率多年来一直是国内外学者关注的热点。在阐述前人聚合物驱相对渗透率曲线测定方法的基础上,按稳态和非稳态两种测试方法对其研究进展做了全面的分析和总结;针对存在的问题和不足,通过推导新的理论计算模型和实验方法的改进,给出了相关问题的解决方法。
Polymer-flooding relative permeability curves are the necessary and important basic data to study the percolating mechanism and compile the developing program of the polymer flooding. However,because of the nonNewton fluid characteristics of the polymer solution passing through the porous media,how to precisely test the relative permeability curves of the polymer flooding has always been the hot point for the scholars all around the world for many years. On the basis of the predecessors＇ measuring methods of the curves,the complete analysis and summarization of the research progress were conducted with the help of steady-state and unsteady-state methods; In view of the existing problems and shortcomings,by means of the new theoretical calculating model and the improvement of the experimental methods,are given,the solutions to the relative problems were presented.
