rate of penetration的用法和樣例：
例句
- At the same deviation, the big WOB can be applied to increase the penetration rate in the straight hole.
在防斜效果不變的情況下，可採用較大鑽壓鑽進，大大提高了直井段的機械鑽速。 - If only raising drilling fluid density to prevent hole sloughing,it will lead to slow penetration rates and long drilling cycles.
如果單純提高鑽井液密度防塌，則導致機械鑽速低，鑽井周期長。
