Title: Rotary drill bit with gauge elements of differing aggressiveness
Inventor: BEUERSHAUSEN CHRISTOPHER C
IPC: E21B10/55
Filed: 2001-08-02
Abstract: A standard rotary drill bit 10 with at least one cutting element (20, figure 1) on its face 18 has circumferentially spaced gauge pads 30. In one embodiment, the gauge pads are not of the same aggressiveness and may include raised cutting or abrading elements 66. The aggressiveness of these elements may vary between the pads, with variation in the composition, shape (figures 11B, 12B, 13B), radial extent and backrake of the elements. It may also vary within a single pad (figure 16). For a more aggressive element, the cutting face is perpendicular to and faces in the direction of drill rotation, whilst for a less aggressive element it is inclined (figure 5). In an alternative embodiment, the cutting elements are located immediately below the gauge pads. The invention results in directional stability for the drill bit and produces a smooth borehole.
