摘要
对聚合物溶液进行了渗流实验和流变性实验 ,研究了聚合物的相对分子质量、相对分子质量分布宽度对聚合物在岩心中的滞留量、阻力因数、残余阻力因数和溶液粘度的影响 .结果表明 :在聚合物溶液的质量浓度及聚合物的相对分子质量分布宽度相同条件下 ,随着聚合物相对分子质量的增加 ,聚合物在岩心中的滞留量、阻力因数、残余阻力因数明显增加 ,聚合物溶液粘度明显增大 ;聚合物的相对分子质量分布越宽 ,聚合物在岩心中的滞留量、阻力因数和残余阻力因数也越大 ;而聚合物溶液的粘度较低 ,相对分子质量分布较窄的聚合物溶液的粘度却较高 .
This paper deals with the effect of polymer relative molecular mass and its distribution on its holdup, resistance coefficient, residual resistance factor by percolation flow experiments of polymer solution in porous media. It also records the rheology determination of polymer solution. The result shows that the polymer holdup is larger, resistance coefficient and residual resistance factor are bigger when relative molecular mass is higher and relative molecular mass distribution is wider. When relative molecular mass is larger, polymer solution viscosity is larger. while relative molecular mass distribution is wider, polymer solution viscosity is smaller.
