Abstract:
1. A method for designing a fixed cutter drill bit, said method comprising: (a) selecting a cutter; (b) selecting an earth formation; (c) engaging said cutter with said earth formation at a selected orientation with respect to said earth formation; (d) determining a force on the cutter; (e) creating a database of the determined force and data representative of at least one of a force applied to the cutter, selected depth of cut, the selected orientation of the cutter, and a geometric parameter of the cutter; (f) simulating a fixed cutter drill bit drilling a formation; (g) determining a force on at least one cutter of the simulated fixed cutter drill bit, wherein the determining comprises: (h) designing a fixed cutter drill bit based on the simulating and the determining the force on at least one cutter of the simulated fixed cutter drill bit; and (i) graphically displaying the designed fixed cutter drill bit.
