displacement efficiency

基本解釋

Rotating casing is helpful to improve effectively mud displacement efficiency and thus improve cementing quality.
旋轉套管可以有效提高水泥漿頂替效率，從而提高固井質量。
The results show that the sweep efficiency and displacement efficiency work different effects on different layers in the severely heterogeneous reservoir.
通過研究表明對于非均質嚴重的油藏，不同層段的波及效率和驅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.
降低界面張力、增強驅油劑的黏彈性、增加驅替速度，有利于提高驅替殘余油膜的驅替效率。

驅油效果
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.
結果表明 ,表面活性劑濃度對驅油效果的影響取決于表面活性劑的界面特性和總用量 ,加入表面活性劑的時機對最終驅油效果影響不大 ,吸附量大的表面活性劑的驅油效果差。
水驅
The oil recovery under water drive is an important factor for the evaluation of water displacement efficiency of a reservoir.
