降低界面张力、增强驱油剂的黏弹性、增加驱替速度,有利于提高驱替残余油膜的驱替效率。
Decreasing interfacial tension or enhancing the viscoelasticity or displacement velocity is favorable to increasing the displacement efficiency of oil film.
欲获得较高的采收率,不仅要尽量降低驱油体系与原油间的界面张力,而且要适当增加驱油体系的黏度。
For higher recovery, not only to minimize interfacial tension between displacement system and the crude oil, but also to appropriately increase the viscosity of oil displacement system.
实验结果表明在恒定温度下界面张力随压力的增加而增大。
The results show that the interface tension decreased with increasing pressure when temperature was specified.
