| Abstract: | According to actual drilling experience, we ameliorate the shape of the flow field. Through the use of numerical simulation, we take all kinds of factors such as three-dimension,rotation,non- symmetry and multi-nozzles into account and analyze the simulation result of flow field under petroleum drill well of a actual PDC drilling bit of a factory, thus it provides guidance to the optimum design of PDC bits to some extent. |
