Deviated Drilling System Utilizing Force Offset

摘要

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.

1. 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.
