摘    要:界面张力弛豫方法是研究油水界面膜微观性质极为有效的方法。采用该方法研究了驱油体系中化学剂如聚合物、十二烷基苯磺酸钠、碱对原油活性组分界面膜扩张黏弹性质的影响,考察了界面上的微观弛豫过程。研究发现,驱油体系中化学剂均对原油活性组分界面膜的性质有一定的影响,尤其是聚合物和碱的加入使界面上出现了特征时间在103s数量级的慢弛豫过程,大大增强了界面膜的弹性。表面活性剂与活性组分间的相互作用造成扩张黏性部分明显变化,而弹性变化不大。图6表1参5

关 键 词:扩张模量  相角  界面张力弛豫  驱油体系

Abstract:The effects of chemicals in FOR system, such as polymer,sodium lauryl benzene sulfonate and alkali, on interfacial dilational viscoelasticity behaviors of decane-water interfaces were investigated by the method of interfacial tension relaxation. It showed that the slow relaxation processes with characteristic time of l03s orders ap-peared with the addition of polymer or alkali. The elasticity of film increased with the appearance of slow relaxation processes.
Keywords:dilational modulus  phase angle  interfacial tension relaxation  FOR system
