摘要：The stick-slip vibration is a common vibration mode of the drill string system during the drilling and it is extremely destructive. The drilling efficiency will be greatly reduced, if the drill gets a bit damaged and the drill rod breaks when the stick-slip vibration occurs. In order to solve this problem, a two-degree-of-freedom focused mass model was established. The controller based on the model reference adaptive control method was designed. The simulation experiment was completed to prove the rationality of the established stick-slip vibration model and the correctness of the control method. The control equipment was developed and the tests above on the well were completed. The experimental results shows that the designed stick-slip vibration control system has validity and stability.
