Abstract
A technique facilitates steering during, for example, a borehole drilling operation. A steering tool is employed to control an orientation of a drill bit or other component. The steering tool comprises a tool body and at least one actuator, e.g. piezo actuator. The at least one actuator, e.g. piezo actuator, is selectively displaced via application of appropriate inputs, e.g. electrical inputs. Controlled application of the inputs enables selective deformation of the actuators in a manner which changes the orientation of the drill bit or other component to a predetermined, desired orientation.
Claims20
A system for use in a well, comprising:
- a drill string comprising a drill bit and a steering tool for controlling the trajectory of a borehole formed by rotating the drill bit, the steering tool comprising a tool body and at least one piezo actuator which is selectively displaced via application of an electrical input to change a drilling orientation of the drill bit.
A method, comprising:
- positioning a plurality of actuators in a tool body of a steering tool;
- coupling the steering tool to a drill bit;
- rotating the drill bit;
- and
- controlling the drilling orientation of the drill bit by selectively displacing individual actuators of the plurality of actuators to bend the tool body.
A system for use in a well, comprising:
- a steering tool for controlling an orientation of a component, the steering tool comprising a tool body and a plurality of actuators, each actuator of the plurality of actuators being selectively displaced via application of controlled inputs to enable selective deformation of the actuators in a manner which bends the steering tool and changes the orientation of the component.
