vertical sweep efficiency

基本解釋

In particular, discontinuous shales, acting as vertical flow barriers, affect significantly the sweep efficiency of oil reservoirs.
特別是，不連續(xù)的頁巖，作為垂直的流體流動(dòng)遮擋，極大影響油罐的洗油效率。
In the vertical direction, follow-up water diverted from the high-permeability layer to the low-permeability layer to enhance the vertical sweep efficiency.
在縱向上，后續(xù)水從高滲層轉(zhuǎn)向低滲透層，提高縱向波及系數(shù)。

Results show that polymer flooding can improve the producing reserves effectively, extend the plane sweep efficiency, reduce the difference between layers and balance the in-layer vertical producing.
結(jié)果表明，聚合物驅(qū)可有效地提高油層的動(dòng)用狀況，擴(kuò)大平面波及系數(shù)，減小層間差異，使層內(nèi)縱向動(dòng)用更加均勻。
