rate of penetration 基本例句 机械钻速 At the same deviation, the big WOB can be applied to increase the penetration rate in the straight hole.在防斜效果不变的情况下,可采用较大钻压钻进,大大提高了直井段的机械钻速。 If only raising drilling fluid density to prevent hole sloughing,it will lead to slow penetration rates and long drilling cycles.如果单纯提高钻井液密度防塌,则导致机械钻速低,钻井周期长。 |
