Bit guidance device and method |
摘要 |
The invention disclosed herein provides a mechanism and method for positive drill bit guidance during well drilling operations. The guidance device includes a control arm or paddle which, due to hydraulic pressure, pivots to steer the drill bit towards its target area. As the paddle applies pressure to the wall of the well, the drill bit is then turned from the contacted area of the well wall in the desired direction.
