Abstract
Aspects of the disclosure can relate to a system including an implement (e.g., a steering tool, a drill bit) tetherable to an equipment string (e.g., a drill string), where the implement includes a steering mechanism to steer the equipment string with respect to a wall of a tubular passage (e.g., a borehole). The system can also include a bearing housing for the equipment string (e.g., connectable to a drill pipe of the drill string), where the bearing housing is rotationally coupled with the implement and rotated. The system can further include an actuation mechanism coupleable between the bearing housing and the steering mechanism to actuate the steering mechanism based upon a rotational orientation of the bearing housing with respect to the steering mechanism.
Claims21
A system comprising:
- a steering tool tetherable to a drill string, the drill string to traverse a borehole, the steering tool including a steering mechanism to steer the drill string with respect to a wall of the borehole;
- a bearing housing connectable to a drill pipe of the drill string, the bearing housing to be rotationally coupled with the steering tool to support the steering tool, the bearing housing to be rotated;
- and
- an actuation mechanism coupleable between the bearing housing and the steering mechanism to actuate the steering mechanism based upon a rotational orientation of the bearing housing with respect to the steering mechanism.
A system comprising:
- an implement tetherable to an equipment string, the equipment string to traverse a tubular passage, the implement including a steering mechanism to steer the equipment string with respect to a wall of the tubular passage;
- a bearing housing for the equipment string, the bearing housing to be rotationally coupled with the implement to support the implement, the bearing housing to be rotated;
- and
- an actuation mechanism coupleable between the bearing housing and the steering mechanism to actuate the steering mechanism based upon a rotational orientation of the bearing housing with respect to the steering mechanism.
A system comprising:
- a drill bit tetherable to a drill string, the drill string to traverse a borehole, the drill bit including a steering mechanism to steer the drill string with respect to a wall of the borehole;
- a bearing housing connectable to a drill pipe of the drill string, the bearing housing to be rotationally coupled with the drill bit to support the drill bit, the bearing housing to be rotated;
- and
- an actuation mechanism coupleable between the bearing housing and the steering mechanism to actuate the steering mechanism based upon a set rotational orientation of the bearing housing with respect to the steering mechanism.
