摘要: 针对流变性和粘弹性越来越复杂的超高相对分子质量聚合物,以牛顿流体为理论基础的毛细管粘度计测定特性粘数的方法误差越来越大。从分析胜利油田现场用超高相对分子质量聚合物的流变性能入手,通过测定聚合物溶液的粘温曲线、流变曲线和固定剪切速率下的粘度,确定了流变仪法在低剪切速率、低浓度下测定超高相对分子质量聚合物特性粘数的实验条件。结果表明,流变仪法测定的超高相对分子质量聚合物的特性粘数值与聚合物的相对分子质量更加接近,ηsp/C~C和lnηr/C~C曲线线性好,测定结果准确可靠。

Abstract: For the super-high relative molecular weight polyacrylamide,the rheological behaviour and viscoelasticity were more complicated.The capillary tube method which was based on Newtonian fluid theory had much bigger error on measuring the intrinsic viscosity.The rheological behaviour of super-high relative molecular weight polyacrylamide of Shengli oilfield was analyzed.The viscosity-temperature curve,rheological curve and the viscosity at fixed share rate were measured.Then the experimental condition under low share rate and low concentration was established.The results show that the rheometer is closer to the real relative molecular weight and the linearity of ηs p /C ~ C and lnηr /C ~ C are better and mensuration is exact and credible.

Key words: Super - high relative molecular weight , Polyacrylamide , Intrinsic viscosity , Rheological behaviour
