| 摘 要： | 研究了彬表面活性剂／聚合物三元复合驱体系与大庆原油间形成低界面张力的特性。结果表明：在降低界面张力方面，碱与表面活性剂之间存在显著的协同效应。而聚合物与碱、聚合物与表面活性剂之间不存在明显的协同效应。本文还初步探讨了超低界面张力的形成机理，并研究了碱浓度、表面活性剂浓度对复合体系／大庆原油间界面张力的影响。

| Abstract: | The interfacial low-tension behavior between alkali/surfactant/polymer triaxial composite system and Daqing crude oil is studied. It is found that there exists an obvious synergistic effect between alkali and surfactant but not between polymer and alkaline or polymer and surfactant. The reason how ultraslow IFT is formed is investigated, and the effect of the alkali concentration and surfactant concentration on IFT is researched. |

| Keywords: | alkali-surfactant-polymer Daqing oilfield interfacial tension synergistic effect enhanced oil recovery |
