Introduction

ER-Gyro-15 MEMS Directional Sensor for GWD

Introduction
With the rapid development of science and technology, MEMS is increasingly widely used in the fields of oil and mining, injecting new vitality into this traditional industry. This is a high-performance product specially designed for oil drilling, mining and other fields. Based on three-axis integrated MEMS gyro and three-axis accelerometer, ER-Gyro-15 can continuously track and measure the change of well inclination angle, tool face angle and azimuth angle.

Features
1) Special-shaped design: adopts a cylindrical design (120mm x Φ30mm);
2) High precision pointing: with a north-seeking accuracy up to 0.25°secψ(1σ); Gyroscope tool face angle up to 1°secL(L stands for latitude)
3) Low power consumption, MAX endurance;
4) Self-alignment function;
5) Continuous tracking and measuring borehole inclination angle, tool face angle, azimuth angle
6) RS-422 serial communication.

Applications
1) North seeking in logging tools/gyros;
2) Pointing, steering and steering of advanced mining/drilling equipment;
3) Oil well inclination measurement and north seeking
4) Pipeline measurement
