| 摘 要： | 利用旋转流变仪分析了超高分子量部分水解聚丙烯酰胺溶液的流变性质,并根据光散射动态模式分析了其在不同浓度和不同盐离子浓度下的尺寸分布.建立了利用多角度激光光散射准确测量驱油用超高分子量聚丙烯酰胺重均分子量(Mw)、均方根回转半径()和第二位力系数值(A2)的方法.准确测量了商品化驱油用超高分子量聚丙烯酰胺FP3630S的这3个参数,分别为Mw=(1.33±0.06)×107,

| Abstract: | This paper analyzed rheologic properties of solutions of partially hydrolyzed polyacrylamide with super high molecular weight by rotate rheometer.The distribution of hydrodynamic diameter of polyacrylamide in brine solutions of different concentrations was measured by dynamic light scattering.The approach to accurately characterize the weight average molecular weight(Mw),mean square radius of gyration() and the virial coefficient(A2) of polyacrylamide with super high molecular weight for oil recovery by multiangle light scattering(MALS) was studied.These three parameters of a commercial polyacrylamide sample(FP3630S) for oil recovery were precisely measured as Mw =(1.33±0.06)×107, |
