| 摘 要： | 本文系统研究了不同离子强度和碱浓度条件下胜利原油－碱水体系的动态界面张力特性，考察了复合驱体系各组分对界面张力的影响，发现胜利原油与碱水间的界面张力在适宜的离子强度和碱浓度条件下达到最低，碱与表面活性剂之间的降低界面张力方面在明显的协同效应，而表面活性剂与聚合物之间不存在明显的协同效应。

| Abstract: | The dynamic interfacial tensions between a Shengli crude oil and alkaline solutions having different pH and ionic strength are measured. The effects of interactions between surfactants, alkaline and/or polymer on dynamic interfacial tensions are studied. It is found that there exists an optimal pH and ionic strength at which the minimum interfacial tension values observed. It is also found that there exists an obvious synergism between alkaline and surfactant but not between polymer and surfactant. |
