    摘要： A drill bit has a bit body intermediate a working face and a shank end adapted for connection to a downhole drill string. The working face has at least three fixed blades converging towards a center of the working face and diverging towards a gauge of the bit, at least one blade having a cone region adjacent the center of the working face. The cone region increases in height away from the center of the working face and towards a nose portion of the at least one blade. An opening is formed in the working face at the center of the bit along an axis of the drill bit's rotation, the opening leading into a chamber with at least one wall. An indenting member is disposed within and extends from the opening, is substantially coaxial with the axis of rotation, and is fixed to the wall of the chamber.

    摘要： In one aspect of the invention, a drill bit assembly has a body portion intermediate a shank portion and a working portion, the working portion having at least one cutting element. The working portion also has an opening to an axial chamber disposed in the body portion of the assembly. The drill bit assembly also has an axial shaft rotationally isolated from the body portion, the shaft being at least partially disposed within the chamber, and partially protruding form the working portion. The shaft is also in communication with an energy adapter disposed within the drill but assembly and is adapted to use relative motion between the body portion and the shaft to provide power to at least one downhole device.

    摘要： In one aspect of the invention a drill bit assembly has a body portion intermediate a shank portion and a working portion, the working portion having at least one cutting element. A shaft is supported by the body portion and extends beyond the working portion. The shaft also has a distal end that is rotationally isolated from the body portion. In another aspect of the invention, a method for steering a downhole tool string has the following steps: providing a drill bit assembly attached to an end of the tool string disposed within a bore hole; providing a shaft extending beyond a working portion of the assembly; engaging a subterranean formation with a distal end of the shaft; and angling the drill bit assembly with the shaft along a desired drilling trajectory.
