Abstract
A system and method for determining drilling parameters based on hydraulic pressure associated with a directional drilling system are disclosed. A drilling parameter associated with a directional drilling system may be determined by measuring hydraulic pressure associated with the directional drilling system during drilling of a wellbore, detecting a change in the hydraulic pressure, and determining a drilling parameter based on the detected change in hydraulic pressure.

A method of determining a drilling parameter associated with a directional drilling system, comprising:
- measuring a hydraulic pressure used by a deflection mechanism of a directional drilling system to generate a deflection angle between a rotational axis of a drill bit and a longitudinal axis of a wellbore during drilling of the wellbore;
- detecting a change in the hydraulic pressure;
- and
- determining a drilling parameter based on the detected change in the hydraulic pressure.
A directional drilling system comprising:
- a drilling tool including a drill bit;
- a steering mechanism including a deflection mechanism capable of generating a deflection angle between a rotational axis of the drill bit and a longitudinal axis of a wellbore using a hydraulic pressure, the steering mechanism configured to direct the drill bit in a desired trajectory using the hydraulic pressure;
- a hydraulic pressure sensor coupled to the steering mechanism and configured to measure the hydraulic pressure;
- and
- directional drilling equipment configured to:
- receive the measured hydraulic pressure from the hydraulic pressure sensor;
- detect a change in the measured hydraulic pressure;
- and
- determine a drilling parameter based on the detected change in the measured hydraulic pressure.
Directional drilling equipment comprising:
- a processor;
- a computer readable memory communicatively coupled to the processor;
- and
- processing instructions encoded in the computer readable memory, the processing instructions, when executed by the processor, operable to perform operations comprising:
- receiving a hydraulic pressure measurement associated with a hydraulic pressure used by a deflection mechanism to generate a deflection angle between a rotational axis of a drill bit and a longitudinal axis of a wellbore;
- detecting a change in the hydraulic pressure measurement;
- and
- determining a drilling parameter based on the detected change in the hydraulic pressure measurement.
