Shock-based damping systems and mechanisms for vibration damping in downhole applications

Systems and methods for damping vibrations of downhole systems are described. The systems include a downhole component configured to be disposed downhole and a shockdamping system at least one of on or in the downhole component, the shock-damping system configured to reduce torsional oscillations of...

Zusammenfassung:	Systems and methods for damping vibrations of downhole systems are described. The systems include a downhole component configured to be disposed downhole and a shockdamping system at least one of on or in the downhole component, the shock-damping system configured to reduce torsional oscillations of the downhole component by imparting a selected shock to the downhole component. The selected shock is selected to generate damping of the torsional oscillations of the downhole system.
