摘要
为了研究油藏条件对表面活性剂性质的影响,本文用TH5000旋转滴超低界面张力仪研究了不同温度和不同盐离子浓度下,表面活性剂溶液与原油之间的油水界面张力。结果说明,本文研究的三种表面活性剂中,温度越高,阴离子表面活性剂H102与原油之间的界面张力越低,非离子表面活性剂W201与原油之间的界面张力先降低后增加,Gemini季铵盐型表面活性剂G101与原油之间的界面张力基本不变;矿化度越高,三种表面活性剂与原油之间的界面张力越低,而且,Ca^(2+)、Mg^(2+)等高价离子的加入使油水界面张力更易降低。比较来看,G101具有耐温、耐盐的良好性能。
In order to study the effect of reservoir conditions on the properties of surfactant,the interfacial tension between surfactant solution and crude oil was studied at different temperatures and concentrations of different salt ions by TH5000 rotating drop ultra-low interfacial tension tester.The results show that with the increase of temperature,the interfacial tension between the anionic surfactant H102 and the crude oil decrease,and the one of the non ionic surfactant W201 decrease first and then increase,and the one of the Gemini surfactant G101 unchanged.With the increase of salinity,the interfacial tension between the three surfactants and the crude oil decrease,and the addition of high valence ions such as Ca^(2+) and Mg^(2+) makes the interfacial tension of oil and water easier to decrease.Comparatively,G101 has good properties of temperature resistance and salt tolerance.
