Abstract
A notable portion of contemporary deep drilling rigs are still equipped with manually-operated lever-based draw-works (hoist) drum mechanical brake actuators, which are used for weight-on-bit (WoB) and rate-of-penetration (RoP) control. In order to meet increasingly stringent requirements on the WoB/RoP control performance, including completely automatic vertical drilling operation (auto-drilling), such mature drilling systems need to be retrofitted with a suitable brake actuator servo mechanism, along with appropriate WoB/RoP control strategy. To this end, this paper presents the development of a weight-on-bit and penetration rate control system based on electrical servomotor-based draw-works brake actuator. The control system has been arranged in the so-called cascade control system structure, wherein the superimposed control loop based on the proportional-integral (PI) WoB controller is commanding the inner RoP PI controller, which in turn provides a position reference to the brake lever mechanism servo-actuator. The proposed WoB/RoP control system has been implemented on industrial control hardware that has been subsequently installed and thoroughly tested on the CROSCO oilfield services Ltd. N-402 land drilling rig.
