Magnetic interference restricted area, can MEMS directional short section put an end to fluxgate?

When fluxgate is frequently calibrated and drilling is stopped in iron ore area, swallowing up the daily operation cost of tens of thousands of yuan - ER-Gyro-19 uses three same in-situ replacement solutions: same interface, same size, and same body type to directly replace fluxgate, lock true north in 30 seconds, and bid farewell to magnetic field dependence forever.

1. Zero transformation revolution of in-situ replacement

Same body type: 1:1 perfect reproduction of fluxgate appearance, design and details, easy to replace
Same size: 136.8×20.3×19mm precision reproduction, suitable for all existing probe card slots
Same interface: aviation plug native support, plug and play, eliminate cable modification
→ End transformation cost: From strong magnetic dilemma to precise navigation, no need to stop drilling, zero system reset

2. Three major technical fulcrums that crush fluxgate

Full point 1: MEMS strapdown inertial navigation technology, stable and reliable
5~125℃ full temperature calibration compensation , immune to extreme temperatures
MEMS strapdown inertial navigation technology removes complex platform mechanical systems, shortens startup time, reduces costs, and improves reliability and stability
Fulcrum 2: The latest three-axis MEMS gyro, probe-level miniaturization

Adopting cutting-edge MEMS gyro technology, with 136.8×20.3×19mm probe-level packaging, it achieves a breakthrough compression of the gyro tool size and can be seamlessly embedded in extremely narrow working spaces

Supports measurement while drilling (GWD) and static continuous dual modes, real-time collection of drilling data, precise control of trajectory, greatly reducing measurement cycles, and significantly improving work efficiency

All-solid-state architecture embedded platform design, with excellent shock and vibration resistance, enhanced environmental adaptability

Based on three-axis MEMS gyro and three-axis strapdown inertial measurement technology complete continuous dynamic tracking and real-time solution of well inclination angle, tool face angle and azimuth angle

Fulcrum 3: High-precision self-seeking north MEMS gyro, strong anti-magnetic

Gyro orientation technology based on the earth's rotation angular velocity sensing, no external magnetic reference or manual calibration is required, completely free from magnetic field dependence, and ensures accuracy without loss in iron ore areas or power grids

30 seconds fast alignment, azimuth accuracy 1°; 90 seconds precise alignment, azimuth accuracy 0.5°, fast and accurate orientation
Well inclination accuracy 0.1° (1σ) | Gyro tool face angle accuracy 1°/secL (L is latitude) | Azimuth accuracy 0.25°secψ (1σ), defining a new benchmark for industry accuracy.
Azimuth/gyro tool face angle: 0~360°｜Gravity tool face angle: -180~180°｜Well inclination angle: 0~90°, full coverage without dead angles, seamless dynamic operation, worry-free throughout the process

High-value scenarios: from restricted areas to safe areas

Casing window opening in iron ore area

Fluxgate magnetized by iron-bearing strata → azimuth drift causes window opening to miss target
ER-Gyro-19 self-seeking north through magnetic fog → window opening positioning error↓
Geothermal ultra-deep well

125℃ high temperature causes fluxgate coil to become brittle and fracture
MEMS solid-state structure → 2000m well depth with no trouble operation
