摘要：
In the process of ''slide'' drilling, the friction between the drillstring and the wellbore is so large that it takes long to implement the tool-face adjustment which is very important to change the current wellbore trajectory. In addition, it is not clear in theory how to adjust the tool face correctly and e-ciently, which results in that the tool face adjustment mostly depends on the driller's experience and is very ine-cient. In this paper, a simplifled transfer function model which describes the tool face adjustment process is proposed. Based on this model, the difierential positive feedback control algorithm is used to improve the response speed of toolface adjustment, and an adaptive method is established to identify and correct the parameters of the control model in real time. Finally, the results of the dynamic simulation show the correctness and robustness of the proposed control algorithm which can increase the dynamic response speed of the tool-face adjustment without overshoot or steady-state error. The parameters of the control algorithm is automatically identifled and corrected without the driller0s experience. Copyright © 2019 Acta Automatica Sinica. All rights reserved.
