摘要： A method for designing a fixed cutter drill bit, includes simulating the fixed cutter drill bit drilling in an earth formation, determining radial and circumferential components of imbalance forces on the drill bit and a Beta angle between the radial and circumferential components of the imbalance forces during a period of simulated drilling, and adjusting a value of at least one design parameter for the fixed cutter drill bit at least based upon the Beta angle. To facilitate drill bit design, the Beta angel can be displayed to a drill bit designer. To improve performance, the method can include repeating the simulating, determining, and adjusting to change a simulated performance of the fixed cutter drill bit. A drill bit may be made according to the design resulting from the method.

摘要： A fixed-head drill bit includes a bit body having a plurality of cutting elements and at least one wear knuckle disposed on the bit body. Each cutting element includes a cutting surface defining a swept cutting profile when the bit is rotated about an axis. The at least one wear knuckle is positioned at least partially within and extending at least partially outside a selected one or more of the swept cutting profiles, allowing the fixed-head drill bit to wear into a more stable configuration.
