Abstract
A drill bit may include a bit body, a plurality of blades on the bit body, and a plurality of cutting elements on the plurality of blades. The drill bit may also include an adjustable depth of cut controller (DOCC) located on a blade to provide depth of cut control for at least one of the plurality of cutting elements. Further, the drill bit may include a positioning unit coupled to the adjustable DOCC and configured to adjust the position of the DOCC relative to the cutting element based on a control signal from a control unit.
Claims19
A drill bit, comprising:
- a bit body;
- a plurality of blades on the bit body;
- a plurality of cutting elements on the plurality of blades;
- an adjustable depth of cut controller (DOCC) located on a blade to provide depth of cut control for at least one of the plurality of cutting elements;
- a threaded channel in the adjustable DOCC;
- a threaded rod engaged with the threaded channel;
- and
- a positioning unit coupled to the adjustable DOCC and configured to adjust the position of the DOCC relative to the cutting element based on a control signal from a control unit.
A drill bit, comprising:
- a bit body;
- a blade on the bit body;
- a cutting element on the blade;
- a depth of cut controller (DOCC) located on the blade to control the depth of cut of the cutting element;
- and
- a spring coupled to the DOCC to provide a biasing force to the DOCC, wherein the spring is oriented to provide a biasing force in a direction on the radial plane of the cutting element.
A method, comprising:
- setting a depth of cut controller (DOCC) to a first position on a blade of a drill bites actuating a threaded rod engaged with a threaded channel of the DOCC;
- drilling a subterranean formation with the DOCC in the first position on the blade of the drill bit;
- setting the DOCC to a second position on the blade of the drill bit by actuating the threaded rod engaged with the threaded channel of the DOCC;
- and
- drilling the subterranean formation with the DOCC in the second position on the blade of the drill bit.
