摘要： 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.

摘要： One disclosed method includes generating a design model for a drill bit, the design model including one or more blades and channels, determining a rotational axis of the design model, dividing the design model into a plurality of unitary volume parallelepipedic elements distributed over at least a portion of the design model, determining a material density and mass of each unitary volume parallelepipedic element and using the material density and mass of each unitary volume parallelepipedic element to calculate a total mass of the design model, calculating a location of an inertia axis of the design model, determining a resulting centrifugal force of the design model upon applying a given angular velocity to the design model and using at least a portion of the total mass and the inertia axis, and modifying the design model to compensate for the resulting centrifugal force and thereby generating a modified design model.
