摘要
本文研究了碱（ＮａＯＨ）／表面活性剂（ＴＲＳ１８）／聚合物（Ｖ２２８）三元复合体系与大庆原油相态特征以及碱和聚合物的加入对相行为影响。结果表明，ＮａＯＨ／ＴＲＳ１８／Ｖ２２８三元复合体系与大庆原油能形成ＷｉｎｓｏｒⅢ型体系，原油与中相微乳液的相间界面张力达到了１０－３～１０－４ｍＮ／ｍ数量级的超低值；碱和聚合物的加入，增加了能形成ＷｉｎｓｏｒⅢ型体系的表面活性剂浓度和体系矿化度范围以及油水比的范围，并降低了相间界面张力值。
This paper studies the phase behaviour of the ternary compound system of alkali(NaOH)/surfactant(TRS18)/polymer (V228)/and Daqing crude oil and the effect of alkali and polymer on phase behaviour. The result shows that the NaOH/TRS18/V228 system can form a Winsor Ⅲ system with Daqing crude oil. The interfacial tension of the crude oil and middle phase microemulsion reaches the very low value of 10 -3 ～10 -4 mN/m order of magnitude. Using alkali and polymer increases the concentration of the surfactant which can form Winsor Ⅲ system and the range of the system salinity and oil/water ratio while decreases the interfacial tension between phases.
