    摘要: In one aspect of the invention, a drill string comprises a drill bit with a body intermediate a shank and a working face, and the working face comprises at least one cutting element. A jack assembly is disposed within the drill bit body and comprises a jack element disposed on a distal end of the assembly. The jack element substantially protrudes from the working face and is adapted to move with respect to the bit body. At least one position feedback sensor is disposed proximate the jack assembly and is adapted to detect a position and/or orientation of the jack element.

    摘要: In one aspect of the present invention, a section of a drill string has a drill bit with a body intermediate a shank and a working face, the working face having at least one cutting element. A jack element is disposed within the drill bit body and has a distal end substantially protruding from the working face. A drive shaft is in communication with the jack element and a rotary source. The drive shaft has a first portion secured within a bore of a tool string component in the tool string and a second portion secured within a bore of the drill bit. The first and second portions of the drive shaft are connected at a pin and box connection wherein the first and second portions are automatically connected as the tool string component is mechanically coupled to the drill bit.

    摘要: A drilling apparatus which includes a drill bit attachable to the drilling end of a drill string, the drill bit including a bit body being attached to a shank and having a working face with at least one cutting element. The drilling apparatus also includes a jack element positioned within a bore of the bit body having a working tip substantially protruding from the working face, and which jack element is also adapted to move with respect to the bit body. One or more position feedback sensors are positioned proximate the jack element and are adapted to detect the axial and/or angular position of the jack element with respect to the bit body.

    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.
