Measurement and Analysis of Stick-Slip and High-Frequency Torsional Coupled Oscillations of Drill String

Shiyou jixie
The self-excited torsional oscillation of the drilling system can reduce the contact force between the bit and the formation or the relative velocity of the cutting force.To mitigate the impact of this mechanism,the torsional oscillation of the drill ...
