摘要： In one aspect of the invention, a drill bit comprises a steel body disposed intermediate a threaded end and a working face. The steel body comprises a plurality of steel blades disposed along an outer diameter of the body and extending radially away from an axis of rotation of the bit. A plurality of cutter elements is disposed on the plurality of steel blades and the blades each comprise a steel stiffness and a steel elastic modulus. At least one of the plurality of steel blades comprises a stiffening element and an overall stiffness at least 3.5 times greater than the steel stiffness.

摘要： In one aspect of the invention, a downhole tool string component comprises a fluid passageway formed between a first and second end. A valve mechanism is disposed within the fluid passageway adapted to substantially cyclically build-up and release pressure within the fluid passageway such that a pressure build-up results in radial expansion of at least a portion of the fluid passageway and wherein a pressure release results in a contraction of the portion of the fluid passageway. The valve mechanism disposed within the fluid passageway comprises a spring. Expansion and contraction of the portion of the fluid passageway varies a weight loaded to a drill bit disposed at a drilling end of the drill string.

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.
