ABSTRACT:
Roller cone drill bits may be formed with cutting elements and cutting structures optimized to increase downhole drilling life of an associated drill bit. The cutting zone, load zone and wear zone of each cutting element may be analyzed by finely meshing each cutting element into many small segments. The number of contacts between each meshed segment and portions of a downhole formation may be determined during discrete drilling time periods. A distribution of sliding velocity for each segment relative to portions of the downhole formation may also be determined during the discrete drilling time periods. Force profiles for each cutting zone may be used to determine associated loading zones. A wear profile for each cutting element may be estimated by combining the associated force profile with the associated distribution of sliding velocity.
