Dynamic wear protection for fixed cutter drill bits

Abstract

An example method for dynamic wear prediction for a drill bit with a cutting structure may include receiving at a processor of an information handling system an unworn profile of the cutting structure and a diamond distribution of the cutting structure. The diamond distribution may include a three-dimensional diamond distribution characterized by radial and axial position on the drill bit. The method may include calculating a final predicted wear profile of the cutting structure based, at least in part, on the unworn profile and the diamond distribution. The method also may include calculating iterations of intermediary wear profiles based, at least in part, on the previous wear profile and the diamond distribution. The final predicted wear profile may indicate a fully worn portion of the cutting structure. A usable life for the drill bit may be determined based, at least in part, on the final predicted wear profile.
