Precision Borehole Trajectory Measurement Using Fiber Optic Gyro Inclinometry
Key Specifications:
Measurement Ranges:
Inclination: 0°-50° (±0.5° accuracy), extendable to 80° (±1.0°).
Azimuth: 0°-360° (±4° accuracy at >4° inclination).
Environmental Tolerance:
Pressure: 25MPa (2,500m depth-rated).
Temperature: -10°C to +60°C operational range.
Data Capacity: Stores 99 datasets (inclination/azimuth pairs).
Technical Advantages:
FOG-Based North Seeking: Eliminates errors from iron casings/magnetic deposits.
Low Power Consumption: 7.4V Li-ion battery enables 20-hour continuous operation.
Compact Form Factor: Ø40mm × 1900mm probe fits standard boreholes.
Applications:
Mineral Exploration: Accurate ore-body delineation in magnetite/hematite zones.
Directional Drilling: Real-time well-path correction for oil/gas wells.
Geotechnical Monitoring: Landslide/precision tunneling stability assessment.
