Abstract(s) :

(Anglais) Understanding destruction mechanisms in high depth conditions is important to manage properly the drilling of very-deep boreholes. Regarding PDC drill bits, cutting mechanism is well known in atmospheric conditions but its comprehension in a confined environment needs to be improved. We use a 3D Discrete Element Method to study the influence of confining conditions and cutting parameters on the Mechanical Specific Energy. We highlight good correlation between numerical models and laboratory experiments. Considering the important cost and difficulties to drive experimental tests on single cutter machines, this elaborated numerical method could be an interesting alternative.
