摘要
三元复合驱 (ASP)溶液与原油的界面张力为任一组分NaOH或ORS -4 1浓度函数。表面活性剂ORS -4 1分子膜性质随碱浓度变化表明 ,碱与表面活性剂间存在相互作用。在高表面压下 ,聚丙烯酰胺对表面活性剂单分子膜影响极小 ,在低表面压下影响显著。破乳剂对ASP膜影响较大。使用常规瓶试法测定了W /O原油乳状液的破乳动力学。碱与表面活性剂浓度对乳状液破乳影响较大 ,当ORS -4 1浓度较高时 ,聚合物影响变小。
The interfacial tensions between solutions containing NaOH and ORS-41, and crude oil were demonstrated to be a function of the two components.Surfactant ORS-41 film characteristics changed as a function of the alkali concentration showing interactions between alkali and surfactant. The polyacrylamide has little effect on the surfactant mono-layer at high surface pressure, but has considerable effect at low surface pressure. De-emulsifier dramatically changed the ASP mono-layer. The break-up of w/o emulsion ...
