摘要: 利用室内物理模拟的方法,对三元复合体系在多孔介质中的流变行为进行了研究,分析了聚合物、碱、表面活性剂浓度和岩芯渗透率对三元复合体系在多孔介质中的流变特征的影响规律,研究结果认为复合体系在多孔介质中呈现出剪切变稀和增稠双重流变特性,复合体系在多孔介质中出现粘弹流变特征的临界剪切速率随着聚合物浓度的升高而减小,随着表面活性剂和碱浓度的增加而增大。

Abstract: The rheological behavior of ASP ( Alkaline -Polymer - Surfactant ) solutions flowing through porous media was investigated with core - flood
tests. The results indicate that the ASP solutions in porous media exhibit rheological characteristics with shear thinning at low shear rate and shear thickening a high shear rate. The critical shear rate decreases with increased concentration of polymer and with de-creased concentrations of both alkaline and surfac-tant.

Key words: Rheology, Combination drive, Chemical flooding, Porous media, EOR
