摘要： Some embodiments of a method for optimizing drilling include determining at least one section of a wellbore for which to determine a schedule for replacing one or more drill bits during drilling the wellbore. Some embodiments of the method also include determining one or more constraints on the schedule for replacing the one or more drill bits. Some embodiments of the method also include determining, based on the one or more constraints, a plurality of scenarios for replacing the one or more drill bits during drilling the at least one section. Some embodiments of the method include determining, by one or more processors, a total cost for each scenario in the plurality of scenarios. Some embodiments of the method include identifying at least one scenario in the plurality of scenarios that has the lowest cost compared to other ones of the plurality of scenarios.
