应用界面粘弹性测定仪测定了聚合物 /表面活性剂 /碱三元复合驱体系的油 /水界面粘度。通过实验发现 ,大庆油田采油三厂原油与注入水、HPAM溶液之间均有较高的界面粘度 ,加入表面活性剂后界面粘度降低 ,老化现象减轻。三元复合体系具有合适的界面粘度和较低的界面张力 ,才会具有较高的驱油效率。
The interfacial viscosity of polymer / surfactant / base ternary flooding system was measured by the interface viscoelasticity tester. It is found through experiments that there is a high interfacial viscosity between crude oil and HPAM solution in the No.3 oil production plant of Daqing Oilfield. The viscosity of the interfacial surface decreases with the addition of surfactant, and the aging phenomenon is alleviated. Ternary composite system with a suitable interfacial viscosity and lower interfacial tension, will have a higher displacement efficiency.
