Abstract
An electro-crushing drill bit is to drill a wellbore, wherein the electro-crushing drill bit comprises a bit body; a ground structure coupled to the bit body; and at least one electrode coupled to a power source and the bit body, the at least one electrode positioned within the ground structure, wherein the at least one electrode comprises, a fixed plate; and a movable plate that is movable relative to the fixed plate.
Claims21
An electro-crushing drill bit to drill a wellbore, the electro-crushing drill bit comprising:
- a bit body;
- a ground structure coupled to the bit body;
- and
- at least one electrode coupled to a power source and the bit body, the at least one electrode positioned within the ground structure, wherein the at least one electrode comprises,
- a fixed plate;
- a movable plate that is movable relative to the fixed plate;
- and
- a plurality of actuators coupled to the movable plate that are positioned approximately equidistance apart and symmetrically around the movable plate.
A downhole drilling system to drill a wellbore, the downhole drilling system comprising:
- a drill string;
- a power source;
- and
- a drill bit coupled to the drill string and the power source, the drill bit comprising, a bit body;
- a ground structure coupled to the bit body;
- and
- an electrode coupled to a power source and the bit body, the electrode positioned within the ground structure, wherein the electrode comprises,
- a fixed plate;
- a movable plate;
- and
- a plurality of actuators coupled to the movable plate to move the movable plate relative to the fixed plate, wherein the plurality of actuators are positioned approximately equidistance apart and symmetrically around the movable plate.
A method for performing directional pulse power drilling, the method comprising:
- drilling, with a pulsed power drill bit, of a wellbore into a subsurface formation using pulse power, wherein the pulsed power drill bit comprise an electrode positioned within a ground structure, wherein the electrode comprises a fixed plate, a movable plate and a plurality of actuators that are positioned approximately equidistance apart and around the movable plate, wherein the drilling comprises,
- generating, by an electrical source, an electrical energy;
- modifying a direction of the drilling of the wellbore, wherein modifying the direction comprises,
- changing, using the plurality of actuators, a position of a movable plate relative to a fixed plate of the electrode;
- and
- periodically discharging the electrical energy through the electrode and into the subsurface formation.
