Directional Drilling TRIZ Cases
- Spindle Orientation Control Using a Virtual Brake
Sensor feedback and motor actuation hold spindle clock position during non-rotating drill string advance, enabling accurate bit steering.
- Rotary Disk Valve Bearing Geometry for Reliable Steerable Drilling
Angled bearing surfaces in a rotary disk valve improve seal life, lower torque, and maintain hydraulic steering control in harsh borehole conditions.
- Virtual Brake Control for Spindle Orientation in Directional Drilling
Sensor feedback and motor control hold spindle clock position during non-rotating drill string advancement, improving steering accuracy.
