🔧 Key Technology for Precise Guiding of Branch Wells: Gyro Tool Directional Subsection

⛽As oil and gas development enters a more refined stage, the application of complex well types such as branch wells and multi-branch wells is becoming increasingly widespread. Compared to conventional wells, branch wells require higher precision in wellbore trajectory control. A directional error can affect the target layer hit rate, increase well workover costs, and even lead to construction failure.

⚙️ Technical Principles of the MEMS Gyro Directional Module
Based on MEMS technology, the MEMS Gyro Directional Module provides a solution independent of geomagnetism. Taking the ER-Gyro-15 as an example, it uses a three-axis MEMS gyroscope + three-axis accelerometer to achieve real-time downhole attitude sensing.

By combining angular velocity and acceleration information with inertial algorithms, the following are calculated:

Azimuth (1°~0.5°)、Inclination (0.1°)、Tool face angle (1/secL)

It maintains stable and reliable measurement accuracy even in casing wells or environments with strong magnetic interference, without relying on external magnetic fields.

✅ Technical Advantages for Adapting to Complex Downhole Environments

Strong Resistance to Magnetic Interference: Independent of the Earth's magnetic field, suitable for casing wells and dense well networks.

High Precision with Small Inclination: Error controlled within 3°, meeting the initial guidance requirements of branch wells.

Shock and Vibration Resistance: All-solid-state structure, adaptable to complex downhole mechanical environments.

High Temperature Resistance: Wide temperature calibration, stable operation up to 125℃.

Compact Structure: Diameter ø30mm/ø25.4mm/ø18.6mm, flexibly integrated into systems of different sizes.

🎯 Key Applications in Branch Wells
Windowing Stage: Still provides effective azimuth data even with small inclination, ensuring the new wellbore enters the designed trajectory.

Build-up Stage: Continuous and stable data output helps engineers adjust drilling parameters in a timely manner, achieving a smooth trajectory transition.

🧭Breaking Magnetic Interference: MEMS North Finder Gives Tunnel Boring Machines an “Absolute Sense of Direction”

For a long time, tunnel boring machines have relied on magnetic compasses or external references for orientation. However, downhole environments are filled with motors, cables, and metal structures that generate strong electromagnetic interference, distorting magnetic measurements. In high-latitude regions or areas with local geomagnetic anomalies, the accuracy of magnetic compasses is also compromised. These issues make traditional orientation methods insufficient for modern high‑precision tunneling requirements.

⚙️ From “External Dependence” to “Autonomous Sensing”
The ER-MNS-06AD MEMS north finder uses a strapdown inertial measurement system with three‑axis MEMS gyroscopes and three‑axis MEMS accelerometers. The built‑in navigation‑grade MEMS gyro enables autonomous orientation without any external reference. By sensing the Earth’s rotation rate, it calculates true north, completely eliminating dependence on the geomagnetic environment.

🛠️ Real‑World Performance in Tunneling Applications
This self‑north‑seeking capability delivers a stable 1° azimuth within 180 seconds and maintains heading and attitude accuracy for over 20 minutes, providing a reliable initial alignment reference for tunnel boring machines.

📦 Compact Integration for Confined Spaces
With dimensions of just 38.6mm × 44.8mm × 25.5mm and a weight of only 70g, the unit can be easily embedded into the control box or structure of a boring machine. Its temperature compensation capability (5°C to 55°C) ensures stable operation in enclosed, fluctuating downhole environments.

✅ Key Applications: Ensuring Tunneling Accuracy and Continuous Operation
On equipment such as boom‑type roadheaders, continuous miners, and mining AGVs, the ER-MNS-06AD serves as an “absolute heading reference.” It provides full‑range azimuth measurement (0–360°) and ±85° inclination measurement, with north‑seeking accuracy (1σ) of 1° secψ and attitude accuracy better than 0.3°. This means that during long‑distance tunnel excavation, frequent manual recalibration is eliminated, reducing auxiliary operation time, ensuring the cutting head advances precisely along the designed axis, and improving both construction quality and safety.

💡 Cost‑Effective Solution for Large‑Scale Deployment
Built on MEMS technology, this north finder achieves ultra‑low cost while meeting the orientation accuracy requirements of construction machinery, making large‑scale deployment feasible. It provides an economical and reliable inertial solution for any equipment that requires precise orientation in non‑magnetic or strong magnetic interference environments.
