displacement efficiency

基本解釋

Rotating casing is helpful to improve effectively mud displacement efficiency and thus improve cementing quality.
旋轉(zhuǎn)套管可以有效提高水泥漿頂替效率，從而提高固井質(zhì)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(duì)于非均質(zhì)嚴(yán)重的油藏，不同層段的波及效率和驅(qū)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(qiáng)驅(qū)油劑的黏彈性、增加驅(qū)替速度，有利于提高驅(qū)替殘余油膜的驅(qū)替效率。

驅(qū)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(jié)果表明 ,表面活性劑濃度對(duì)驅(qū)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(shí)機(jī)對(duì)最終驅(qū)油效果影響不大 ,吸附量大的表面活性劑的驅(qū)油效果差。
水驅(qū)
The oil recovery under water drive is an important factor for the evaluation of water displacement efficiency of a reservoir.
油藏水驅(qū)開發(fā)潛力是分析評(píng)價(jià)油藏開發(fā)開采水平的重要參數(shù)。
