METHODS FOR MODELING WEAR OF FIXED CUTTER BITS AND FOR DESIGNING AND OPTIMIZING FIXED CUTTER BITS |
摘要 |
<p>In one aspect, the invention provides a method for modeling the wear of a fixed cutter bit drilling earth formations. A method for determining wear of a fixed cutter drill bit includes simulating the fixed cutter drill bit drilling an earth formation; determining a cutter-formation interaction force and a relative sliding velocity of a selected area on a cutting surface on a cutter of the fixed cutter drill bit during the drilling; and calculating a wear rate of the selected area based on the cutter-formation interaction force and the relative sliding velocity.</p> |
