| 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

| 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 |
