displacement efficiency

基本解释

Rotating casing is helpful to improve effectively mud displacement efficiency and thus improve cementing quality.
旋转套管可以有效提高水泥浆顶替效率，从而提高固井质量。
The results show that the sweep efficiency and displacement efficiency work different effects on different layers in the severely heterogeneous reservoir.
通过研究表明对于非均质严重的油藏，不同层段的波及效率和驱替效率所起的作用不同。
Decreasing interfacial tension or enhancing the viscoelasticity or displacement velocity is favorable to increasing the displacement efficiency of oil film.
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。

驱油效果
The results indicate that the effect of surfactant concentration on displacement efficiency is determined by its surface characters and total quantity. The injecting time of surfactant has little effect on displacement efficiency.
结果表明 ,表面活性剂浓度对驱油效果的影响取决于表面活性剂的界面特性和总用量 ,加入表面活性剂的时机对最终驱油效果影响不大 ,吸附量大的表面活性剂的驱油效果差。
水驱
The oil recovery under water drive is an important factor for the evaluation of water displacement efficiency of a reservoir.
