报告摘要

in this talk i will guide the audience through the path of the new drilling technology development. the resonance enhanced drilling (red) is a new patented downhole drilling technology which has been conceived and developed by the centre for applied dynamics research at the university of aberdeen. the red technology offers unprecedented improvement in progression rates, reduction of cost and much smaller environmental footprint. the fundamental difference between red and the current methods of a wellbore creation is the generation of a propagating dynamic crack zone ahead of the drill-bit by inducing high frequency axial loading. the focus will be given focus the mathematical modelling and experimental verification of the dynamics effects associated with red and how to optimise the control parameters to achieve the best progression rates. the red technology applies an adjustable high frequency dynamic stress in combination with rotary action. the resonance conditions between a drill-bit and drilled formation is maintained for varying drilling conditions by adjusting the frequency and amplitude of the excitation. the lecture will focus on the full scale experimental studies, where over 700% improvement in rates of penetration (rop) when compared to the rotary drilling was achieved.
