ER-Gyro-15: MEMS Directional Sensor that Redefines Downhole Exploration Accuracy

In traditional industrial fields such as oil drilling and mining, accurate downhole position measurement has always been the core problem of technological breakthroughs. Traditional gyroscopes are limited by their large size, poor environmental adaptability, and reliance on magnetic field calibration, making it difficult to meet the needs of efficient exploration under complex working conditions. The birth of the ER-Gyro-15 MEMS directional sensor, with its miniaturized design, all-solid-state impact resistance, and unparalleled measurement accuracy, has brought disruptive solutions to the industry.

1. Miniaturized design: breaking through the limits of downhole space

The size of traditional gyroscopes often limits their deployment in narrow wells or complex equipment. ER-Gyro-15 redefines the miniaturization standard of MEMS sensors with its extreme size of 30mm in diameter and 120mm in length. Its compact form can be easily integrated into downhole measurement tools. This design completely solves the pain point of "space competition" for downhole equipment and provides the possibility for multi-sensor collaborative operation.

2. All-solid-state + high performance: double guarantee for precise measurement

ER-Gyro-15 adopts the strapdown inertial measurement technology of three-axis integrated MEMS gyroscope and accelerometer, combined with the all-solid-state design, to achieve full-dimensional dynamic tracking of well inclination (accuracy 0.1°), tool face angle, and azimuth (30 seconds fast alignment accuracy 1.5°, 90 seconds accuracy 0.5°). Its advantages are:

Shock and vibration resistance: The all-solid-state structure has no mechanical moving parts and can work stably in high-vibration and strong-impact drilling environments;

Self-seeking north and no magnetic interference: No need to rely on geomagnetic reference, avoid interference from metal pipes or downhole magnetic fields, and ensure the independence of azimuth measurement;

Dual modes of while drilling and continuous measurement: Support real-time while drilling data feedback, and can also be used for continuous trajectory mapping after completion to meet full-cycle requirements.

3. Extreme environment adaptability: challenging the boundaries of industrial scenarios

In the extreme temperature range of -5℃ to 125℃, ER-Gyro-15 uses full temperature scale compensation technology to ensure the long-term stability of measurement data. Whether it is a high-temperature drilling platform in the desert or a deep mining operation, its performance is not affected by the environment.
