    Introduction

    MEMS Gyro Directional Module(Can replace fluxgate directional module)

    Introduction
    ER-Gyro-19 uses an electrical interface and mechanical structure compatible with the fluxgate orientation module. It can be directly replaced in situ without modifying the hardware architecture of the probe or logging equipment, greatly reducing the equipment modification cost and installation complexity.

    Traditional magnetic sensitive element inclinometers cannot guarantee the azimuth measurement accuracy in casing, tubing, drill pipe and well sections affected by magnetic interference. For such abnormal magnetic field environments, gyro orientation technology based on the earth's rotation angular velocity sensing is required.

    ER-Gyro-19 is equipped with a high-precision MEMS gyroscope with self-seeking function. By integrating the real-time data of the three-axis MEMS gyroscope and the three-axis accelerometer, it can perform high-precision tracking and holding measurements of azimuth, well inclination and tool face angle in real time under large random vibration conditions, which is especially suitable for measurement while drilling scenarios.

    The azimuth and tool face angle can be output normally at small well inclination, with the accuracy kept within 3°, which solves the technical defect that most gyro logging tools cannot output effective azimuth at small well inclination.

    The device supports measurement while drilling, point measurement and continuous measurement, can quickly collect drilling data, control drilling trajectory, greatly shorten measurement time, and significantly improve operation efficiency. It is an ideal equipment in the fields of oil and gas logging.
