Surfactant: in addition amount of low also can significantly reduce the interfacialtension of the material.
表面活性剂:在添加量很低的情况下也能显著降低界面张力的物质。
2
Mechanism of low interfacialtension system increasing oil displacement efficiency is analyzed based on microscopic oil displacement experiments.
通过微观驱油实验结果分析低界面张力体系能够提高驱油效率的机理。
3
Decreasing interfacialtension or enhancing the viscoelasticity or displacement velocity is favorable to increasing the displacement efficiency of oil film.
