摘要
通过测定ＡＳＰ溶液在孔隙介质中的流变特性，提出了“达西粘度”的概念，并研究了它与残余阻力系数的关系，从而将ＡＳＰ／油体系相对渗透率曲线测试中水相粘度的确定问题转化为研究流体的残余阻力系数与表观粘度的关系．实验结果表明，本文提出的思路和方法是测定ＡＳＰ驱油体系相对渗透率曲线的可行途径。
This paper presents the conception of Darcy viscosity after the measurement of the rheo logical property of ASP fluid flowing through porous medium and studies its relationshipwith the residual resistamce factor (Fir).The problem of how to determine the water phasevisicosity in measuring the relative permeability curve of ASP/oil system has been transferred to the study of the relationship betwween Darcy viscosity and Frs as well as the apparent viscosity. The experimental results show that the idea advanced in this paper is an effective method to measure the relative permeability curve in ASP flooding.
