Abstract
Systems and methods for predicting drill bit wearing state using drilling parameters and formation properties are disclosed. The methods include, for each of a plurality of past bit runs, obtaining a measured rock property value and a measured drilling variable value for the past bit run, and obtaining a measured dull grade for a drill bit used for the past bit run. The methods also include determining parameters of a functional relationship between the measured dull grade, the bit run time, the measured rock property value, and the measured drilling variable value, and predicting a predicted dull grade for a future bit run using a new drill bit. The methods further include replacing the new drill bit with a replacement drill bit at a time based, at least in part, on the predicted dull grade.
