wob 中文意思是什麼
wob
解釋
WOB ＝washed overboard 浪擊落水（指被浪沖出弦外）。-
The hydrodynamic propulsor takes drill fluid as power source, with the aid of the axial load produced by the pressure drop of the bit nozzle, makes the axial force act on the bit to produce wob, making up for the insufficient wob, ensuring the bit feeding smoothly and improving the penetration rate
這種推進器以鉆井液為動力源，藉助鉆頭噴嘴壓降產生的軸向載荷，使軸向力直接作用於鉆頭產生鉆壓，彌補有效鉆壓不足，保證鉆頭平穩鉆進，提高機械鉆速。 -
In drilling high angle deviated holes, friction is the main factor affecting the effective wob
在大斜度定向井鉆井過程中，摩擦阻力是影響有效鉆壓的主要因素。 -
Application of downhole hydrodynamic propulsors solves the problem of exerting wob, and are helpful to enhancing penetration rate
井下液力推進器的應用在一定程度上解決了鉆壓的施加問題，有利於提高鉆進速度。
