研究了碱 表面活性剂 聚合物 (简称ASP)体系的基本流变性以及流变参数在岩心中沿渗流方向的变化规律。结果表明在一定剪切速率范围内 ,ASP体系的流变性符合幂律流变模式 ;室内实验证明ASP体系的流变参数沿渗流方向上是变化的 ,并且有一定的规律 ;根据实验数据推出了ASP体系流变参数的经验模型。本项研究为三元复合驱配方筛选及复合驱油井流入动态研究提供了依据
The basic rheological properties of alkali-surfactant polymer (ASP) system and the variation of rheological parameters along the seepage direction in core were studied. The results show that within a certain shear rate range, the rheology of ASP system accords with the power-law rheological model. Laboratory tests show that the rheological parameters of ASP system vary along the direction of seepage and have certain rules. According to the experimental data, Empirical model of rheological parameters in ASP system. This study provides the basis for the screening of ASP flooding and the dynamic study on the inflow of composite flooding wells
