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。
The rheological behavior of ternary composites in porous media was studied by means of in-house physical simulation. The effects of polymer, alkali, surfactant concentration and core permeability on the rheological properties of ternary composites in porous media The results show that the composite system exhibits the dual-rheological properties of shear thinning and thickening in porous media. The critical shear rate of viscoelastic rheological properties of the composite system in porous media increases with the polymerization The increase of concentration decreased, with the increase of surfactants and alkali concentration.
