    摘要: A drill bit with a drill bit body having a cutting structure face. A pin is formed on the drill bit body for attaching the drill bit body to a drill string. The pin has a first central axis to be aligned with the drill string when attached and the cutting structure face has a second central axis. The second central axis is misaligned relative to the first central axis.

    摘要: In one aspect, the invention provides a method for modeling the performance of a fixed cutter bit drilling an earth formation. In one embodiment, the method includes selecting a drill bit and an earth formation to be represented as drilled, simulating the bit drilling the earth formation, displaying the simulating, and adjusting at least one parameter affecting the performance. The method of design is used to make a fixed cutter drill bit. In another embodiment the method includes numerically rotating the bit, calculating bit interaction with the earth formation during the rotating, and determining the forces on the cutters during the rotation based on the calculated interaction with earth formation and empirical data.
