摘要(Abstract)：

在研究聚合物溶液流变性基础上 ,通过测定聚合物溶液的阻力系数与残余阻力系数 ,确定了聚合物溶液在多孔介质中的有效粘度。建立了非稳态法聚合物驱油的实验技术和方法 ,设计了 3种实验方案。通过大量的实验 ,对常规水驱油实验和聚合物驱油实验的相对渗透率曲线进行对比 ,说明了聚合物驱油体系的相对渗透率曲线特点 ,并研究分析了聚合物溶液在岩石中吸附 滞留对相对渗透率的影响。实验结果真实地反映了聚合物驱油过程的多相渗流规律
Basing on the study on the rheological property of polymer solution and the measurement of resistance coefficient and residual resistance coefficient of polymer solution, this paper determines the efficient viscosity of polymer solution in multi porous media and eliminates the effect of the adsorption/remain and non Newton flow effect. It constructs non steady state method and designs 3 experimental programs. Through a large number of experiments, it compares the relative permeability curves of normal water flooding experiment and polymer flooding experiment. It gives the characteristic of the relative permeability curve of polymer flooding system and analyzes the effect of polymer solution on adsorption/remain in rocks. The experimental result reflects the multi phase seepage rule in the process of polymer flooding.
