PIPE STRING VIBRATIONS CAUSED BY TOP DRIVE RIG MASS IMBALANCE
Abstract
Operation of the top drive systems has revealed a significant disadvantage, in particular, large-amplitude vibrations of the system "top-drive - drilling rig - drilling column", which inevitably leads to a failure of the drive mounts to the rig, accumulation of fatigue damages of the drill column and other harmful consequences that affect the reliability of the whole system. Based on the mechanical model of the spinner rig an analytical study of the dynamics of the top drive system was conducted and the solutions that characterize the nature of the system oscillations were obtained and analyzed. The relationships of forced vibrations amplitude of the top drive system were analyzed. As a result the operation parameters of the drive load at which the resonance phenomenon occurs were determined.
