Borehole Drives TRIZ Cases
- Downhole Tractor Motor Load Control for Wheel Slippage Reduction
Real-time motor voltage control balances wheel loads in downhole tractors to reduce slippage, torque divergence, and premature wear.
- PCD Bearing Layout for Rotating Control Device Sealing Loads
Polycrystalline diamond bearings help rotating control devices carry radial and axial loads while preserving smooth rotation and a fluid-tight seal.
- Rotary Lock Starter Gear Gap for Full-Torque Unlocking
A circumferential gear gap lets a small rotary engine build torque before engagement, improving rotary lock unlocking reliability.
- Spectacle Blind Swinging Mechanism for Heavy Pipe Isolation
A shaft-and-housing swing mechanism rotates heavy spectacle blinds at pipe flange joints without cranes, cutting labor and improving safety.
- Integrated Rotating Seal Assembly for RCD and BOP Pressure Control
A dual-mode seal and bearing assembly combines RCD and annular BOP functions to simplify drilling pressure control and fluid sealing.
