摘要
本文系统地研究了由非离子表面活性剂ＮＯＳ构成的复合体系与大庆油田原油间的界面张力。探讨了时间、ＮａＯＨ浓度、地层水矿化度、活性剂浓度及聚合物种类和用量对界面张力的影响。结果表明，由该活性剂构成的三元复合体系能在较宽的地层水矿化度、较宽的活性剂浓度及碱浓度范围内与大庆油田原油形成超低界面张力（１０－３ｍＮ／ｍ数量级）。
This paper discusses the interfacial tension between non-ionic surfactant NPS included combination system and the crude oil of Daqing oil field. The effects of time, NaOH concentration, surfactant concentration, salinity of formation water, different polymers and their contents on interfacial tension are studied. The results suggest this surfactant-combined system can form ultralow interfacial tension (10 ^-3mN/m) with the crude oil in Daqing oil field in a wide range.
