摘　　要：考察了盐、碱、表面活性剂及实验温度对生物聚合物（黄胞胶）驱油体系流变性的影响．研究结果表明，生物聚合物与阴离子表面活性剂（石油磺酸盐）相互作用强烈．在流变性方面体现出良好的协同效应，这种协同效应对低界面张力—流度控制复合驱十分有利．对几类生物聚合物驱油体系，包括聚合物驱、碱－聚合物驱、碱－表面活性剂－聚合驱的不同配方的而变性考察结果表明，在常用的几种描述聚合物溶液流变性的模型中。The effects of salinity, alkali, surfactant and temperature on the rheologicalbehariour of xanthan biopolymer flooding systems was studied. The results showed that theinteraction between anionic surfactants (Petroleum sulphate)and xanthan is apperent.Thereis a beneficial synergistic effect for mobility control in Chemical EOR processes,Therelationship between shear stress and shear strain rate of some solutions including xanthan,alkali and sutfactant, was investigated.The power law relationship model(Ostwald model)isconsidered as the best one among several usual models for describing the polymer rheologicalbehaviour.
