MEMS Gyroscope Directional Module for GWD: New solutions for well logging

In the fields of oil and gas logging, accurate measurement of well inclination angle, tool face angles and azimuth angles is crucial to controlling the drilling trajectory and ensuring the smooth progress of mining operations. The azimuth measurement accuracy of traditional magnetic sensitive element in casings, oil pipes, drill rods and well sections affected by magnetic interference is difficult to ensure. The emergence of the ER-Gyro-15 MEMS gyro directional module effectively solves these problems.

High accuracy measurement and fast alignment

ER-Gyro-15 adopts gyro orientation technology based on earth's rotation angular velocity sensing. It is not affected by magnetic fields and can also ensure high accuracy of azimuth measurement in well sections with strong magnetic fields.

It can realize dynamic continuous tracking measurement of well inclination angle, tool face angle and azimuth angle. Supports drilling measurement, point measurement and continuous measurement, and can quickly collect drilling data and control drilling trajectory.

The azimuth angle accuracy can reach 0.25°, 30s fast alignment, 1.5°, 90s accurate alignment, and 0.5° azimuth accuracy.

The well inclination angle measurement accuracy is 0.1°, and the surface angle accuracy of the gyroscope tool reaches 1°/secL (L is latitude), meeting the high-precision trajectory control requirements of well logging.

Super the size of traditional gyro tools

The device has achieved a major breakthrough in size, with a cylinder design with a diameter of only 30mm and a length of 120mm.

It can easily be embedded in narrow front-end spaces such as tube probes, making it convenient for flexible deployment in complex downhole environment, greatly improving the convenience of measurement.

Strong environmental adaptability

The all-solid-state design gives the ER-Gyro-15 excellent impact and vibration resistance, and can operate stably even in harsh downhole operating environments to ensure the accuracy of measurement data.

At the same time, its 5-125°C full temperature calibration compensation function can adapt to high-temperature or low-temperature environments to ensure the normal operation of the equipment in extreme environments.
