MEMS Directional Sensor Newly Released: an Innovative Tool for Oil Drilling Technology

In the oil drilling industry, accurate downhole orientation, wellbore trajectory control, and measurement technology are the key to ensuring efficient and safe operations.

ERICCO has officially released the ER-Gyro-15, a MEMS gyro tool directional sensor specially designed for oil well logging and HDD, which can realize measurement while drilling or continuous measurement.

Core features meet industry needs

ER-Gyro-15 adopts the latest and most advanced MEMS gyro technology. Compared with traditional downhole measurement tools (DTG, RLG, FOG), ER-Gyro-15 provides innovative solutions for complex drilling environments with its unique advantages of miniaturization, high precision, low power consumption and strong impact resistance.

ER-Gyro-15 has the function of self-seeking north, which can realize high-precision measurement while drilling and continuous measurement. It can continuously measure the change of well inclination, tool face angle and azimuth in real time. The algorithm solves the well trajectory in real time.

Precise measurement ensures the accuracy of operations

High-precision pointing: North-seeking accuracy can reach 0.25°secψ (1σ), gyro tool face angle accuracy is 1°secL (L is latitude), and well inclination alignment accuracy is 0.1° (1σ).

Fast self-alignment: 30s fast alignment, azimuth accuracy can reach 1°; 90s precise alignment, azimuth accuracy can reach 0.5°. Reduce manual intervention and adapt to complex downhole environments.

Wide measurement range: The azimuth and gyro tool face angle measurement range covers 0~360°, the well inclination measurement range is -180~180°, and the tilt angle measurement range is 0~90°, which is suitable for a variety of operating scenarios.

Compact design, subverting traditional size

Special design: It adopts a cylindrical design with a diameter of only 30mm and a length of 120mm, ≤150g, subverting the size of traditional gyro tools, extremely small, suitable for various narrow underground spaces.

Near-bit installation: It is easy to adapt to various downhole tools, can be directly embedded in the drilling rig probe and installed near the drill bit. Whether in horizontal wells, large displacement wells or complex structure wells, it can work stably.

Strong adaptability, suitable for extreme environments

All-solid-state design: no mechanical moving parts, excellent impact resistance and vibration resistance, suitable for highly dynamic environments, and can work stably in high-frequency vibrations underground.

High temperature resistant design: 5-125°C full temperature calibration compensation, adaptable to extreme environments, and miniaturized design can also effectively extend the usage time of the thermos bottle.

Not affected by magnetic field: It has the function of self-seeking north and is not affected by magnetic materials, which effectively solves the problem of wellbore trajectory measurement accuracy under magnetic field interference.

The launch of ER-Gyro-15 brings more advanced and reliable directional solutions to the oil drilling industry. It will play an important role in oil exploration and development, helping the industry achieve efficient, safe and sustainable development.
