摘要： Walk characteristics of an earth-boring rotary drill bit may be predicted by measuring locations and orientations of cutting elements thereof and calculating the magnitude and direction of an imbalance force of the drill bit using the measurements obtained. The calculated imbalance force may be compared to the imbalance force of at least one other drill bit having a calculated imbalance force and observed walk characteristics. An earth-boring rotary drill bit may be designed by constructing a database including the magnitude and direction of a calculated imbalance force and observed walk characteristics for a number of drill bits. Desired walk characteristics are selected, the database is referenced, and the bit may be configured to exhibit an imbalance force selected to impart desired walk characteristics to the drill bit. Drill bits are configured to exhibit an imbalance force oriented in a predetermined direction relative to a blade of the drill bit. A system may be employed to monitor the imbalance force of an operating drill bit and to provide or implement desirable operational parameters to compensate for same.

摘要： A drill bit includes a bit body having a face on which two different types of cutting elements are disposed, the first type being cutting elements suitable for drilling at least one subterranean formation and the second type being cutting elements suitable for drilling through a casing bit disposed at an end of a casing or liner string and cementing equipment or other components, if such are disposed within the casing or liner string, as well as cement inside as well as exterior to the casing or liner string. The second type of cutting elements exhibits a relatively greater exposure than the first type of cutting elements, so as to engage the interior of the casing bit and, if present, cementing equipment components and cement to drill therethrough, after which the second type of cutting elements quickly wears upon engagement with the subterranean formation material exterior to the casing bit, and the first type of cutting elements continues to drill the subterranean formation. The first type of cutting elements may comprise superabrasive cutting elements and the second type of cutting elements may comprise abrasive or superabrasive cutting elements comprising a plurality of configurations.
