How does MEMS Gyro Reshape the Core Perception of Drilling?

In the pursuit of underground treasures (oil, gas, minerals) and the exploration of the earth's mysteries (geological engineering), accurately controlling the direction of the drill bit, depicting the borehole trajectory in real time, and obtaining reliable data in complex formations are the continuous challenges faced by directional drilling and logging operations. How to penetrate the rock barrier and accurately sense every subtle movement of the drill tool?

"Gyro drilling" technology is the weapon to solve this problem. It no longer relies on traditional means, but integrates micro gyroscopes and accelerometers to solve the key attitude parameters of the drill tool in real time: well inclination (degree of inclination), azimuth (horizontal pointing) and tool face angle (drill bit direction).

At this technological forefront, the ER-3MG-091 MEMS gyroscope stands out and becomes the cornerstone of building underground precise perception capabilities. Relying on MEMS (micro-electromechanical system) technology, it achieves amazing high performance under the extremely miniaturized design, and continuously outputs stable and high-precision angular velocity data.

1. Break through the accuracy limit and lock the trajectory:

Error accumulation nemesis: Its core advantage lies in the extraordinary zero bias stability (optional 0.01°/hr or 0.02°/hr). This means that in the long drilling process (especially ultra-deep wells or long-distance horizontal wells), it can effectively suppress the accumulation of errors and ensure the long-term accuracy of trajectory correction.

Cornerstone of long-term trust: The angular random walk index is as low as < 0.0025°/√h, which is the fundamental guarantee for the accuracy of attitude and heading calculation for a long time, and the small error is almost not magnified over time.

Full coverage of dynamic range: Provides three ranges of 50°/s, 100°/s, and 200°/s, and can calmly cope with various complex working conditions from conventional drilling to high-speed rotation of drilling tools.

2. Small size, big energy, no fear of space constraints:

Extremely compact design: It adopts a cylindrical structure with a diameter of only 30mm and a length of 120mm, and the overall weight is less than 150 grams. This miniaturization breakthrough allows it to be easily integrated into key downhole equipment with extremely limited space, such as:

Measurement while drilling (MWD) system

Logging while drilling (LWD) tool

Compact gyro inclinometer

Small borehole tool: It significantly reduces the requirements for borehole diameter, providing unprecedented high-precision attitude measurement for small-diameter directional drilling (such as geological exploration holes and branch wells).

3. Laughing at the test of hell, real-time data access:

Temperature fearless warrior: The standard model can work stably in a wide temperature environment of -45°C to +85°C. Facing more severe deep geothermal or ultra-deep well environments, the ER-3MG-091H high-temperature model can challenge the extreme temperature of -40°C to +125°C, fully meeting the demanding logging needs.

Information highway channel: Using RS-422 high-speed communication protocol, the transmission baud rate is as high as 460,800 bps under the default configuration, and the data refresh rate soars to 400Hz. This ensures millisecond-level capture and real-time, lossless transmission of drill tool posture changes, providing immediate and complete basis for ground decision-making.
