摘　　要：研究了不同剪切降解聚合物对原油模拟油与模拟水体系的界面张力、界面剪切粘度、Zeta电位的影响。结果表明,水相为疏水缔合聚合物溶液时,随聚合物剪切降解程度增加,原油模拟油油水界面张力降低,界面剪切粘度减小,Zeta电位的绝对值总体呈增加趋势。The effect of the different shear degradation polymer on interfacial tension,interfacial shear viscosity and Zeta potential between the model oil and formation water were investigated. Results showed that, as the shear degradation degree of polymer in aqueous phase was increased, the interracial tension and the interracial shear viscosity decreased,the Zeta potential increased for crude model oil/polymer solution.
