摘要
A method for designing a fixed cutter drill bit includes simulating the fixed cutter drill bit drilling in an earth formation, determining a dynamic centerline trajectory of the drill bit, and adjusting at least one design parameter based upon the graphical display of at least the dynamic centerline trajectory. To improve performance, the method can include graphically displaying the dynamic centerline trajectory and/or repeating the simulating, determining, displaying and adjusting to change a simulated performance of the fixed cutter drill bit. A drill bit design may be selected and a drill bit may be made according to the design resulting from the method of designing.
