sweep drive的意思|示意

Steam drive pilot test in Block Qi40 has achieved ideal development result, but the sweep efficiency is low and stable production period is short because of reservoir heterogeneity.

齐40块蒸汽驱先导试验取得了较为理想的开发效果，但由于受油藏非均质性的影响，蒸汽驱过程中出现了蒸汽波及效率低、稳产时间短等现象。

Lastly, sweep experiment and drive experiment were made.

最后，进行了扫频实验和驱抖实验。

At normal temperatures, the oil driving efficiency and the sweep efficiency of water driving are low, and the crude viscosity increases after water drive.

常温驱油效率低，水驱波及系数小，且水驱后原油黏度增加。
