Modelling of the vibro-impact drilling system is undertaken in this study, and the results of the numerical analysis and comparison between two selected models are presented. The first one is a newly developed model of an existing experimental rig (three masses model) and the second one is a simplified low dimensional model (Pavlovskaia et al., 2001 (22)) created to describe the dynamic interaction between the drill-bit and the drilled formation. The optimal loading parameters are identified in… CONTINUE READING
