Auto Driller System |
|
|
- Auto driller systems include two types: one type is an independent motor auto driller system and the other is a disc/band brake auto driller system.
- The independent motor auto driller system consists of feeding motor, sensor, AC frequency conversion control system, and other equipment. Constant WOB and constant ROP can be realized through speed feedback and torque control in order to increase drilling efficiency and decrease working intensity for the driller.
- The disc/band brake auto driller system can provide an auto drilling function by controlling the disc/band brake. WOB can be controlled in real time and ROP can be increased by controlling the disc/band braking torque of the drawworks in the driller system. Besides the above basic functions, this system can also provide safe drilling monitoring functions, such as the Crown-O-Matic.
