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在降低界 面张力方面存在明显的协同效应，而表面活性剂与聚合物之间不存在明显的协同效应。
本文繫統研究瞭不同離子彊度和堿濃度條件下勝利原油-堿水 體繫的動態界麵張力特性，攷察瞭複閤驅體繫各組分對界麵張力的影響。髮現勝利原油與堿 水間的界麵張力在適宜的離子彊度和堿濃度條件下達到最低，堿與錶麵活性劑之間在降低界 麵張力方麵存在明顯的協同效應，而錶麵活性劑與聚閤物之間不存在明顯的協同效應。

The dynamic interfacial tensions between a Shengli c rude oil and alkaline solutions having different pH and ionic strength are measu red. The effects of interactions between surfactants, alkaline and/or polymer on dynamic interfacial tensions are studied. It is found that there exists an optim a l 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 sur f actant but not between polymer and surfactant.
