Precise application of high-performance dynamic FOG north seeker in mining and oil exploration

 

The orientation accuracy of drilling equipment directly affects the efficiency and safety of logging drilling, tunnel excavation, and ore body positioning. During underground drilling operations, the vibration and attitude changes of the drilling rig are frequent, and traditional mechanical gyroscopes or magnetic compasses are difficult to work stably.

ER-FNS-01D high-performance dynamic FOG north seeker can achieve real-time accurate north seeking and attitude following in a vibrating environment. The north seeking accuracy can reach 0.5°, and the attitude measurement accuracy can reach 0.03° (1σ). Dynamic north-seeking technology can provide the true north direction of the carrier in real time. The working latitude of 65°N-65°S covers major mining areas and oil and gas fields around the world, ensuring that the drilling rig can still accurately control the drilling direction even when tilted or vibrating.

The compact size of 100×100×75mm and the lightweight design of 1kg make it easy to integrate into drilling equipment. Its core technical advantages are precisely targeted at complex working conditions:

Fast and precise dual modes: Supports 30-second fast alignment (azimuth accuracy 1°) and 90-second precise alignment (azimuth accuracy 0.5°), significantly shortening the equipment startup time. It can quickly establish the north reference after the drilling rig is in place. At the same time, its 20-minute accuracy retention capability allows the drilling rig to quickly resume operations after a short stop, reducing the time loss caused by repeated alignment.

Full environment adaptability: 5℃-55℃ full temperature range compensation technology adapts to the temperature difference between the deep mine and the field; there is humidity, dust and potential electromagnetic and metal interference in the mine, and the ER-FNS-01D is not affected by the magnetic field, which completely avoids the influence of the electromagnetic environment on the measurement results.

Strong vibration adaptability: The built-in shock absorber design can withstand 20Hz-2000Hz, 6.06g vibration environment, solving the problem of accuracy drift caused by vibration in dynamic operations of traditional north-seeking equipment.

New tools for drilling, well logging and mining, don’t you know about it yet?

 

In the fields of directional drilling, logging and mining, accurate control of direction and attitude is the core of successful operations. The complex industrial environment makes traditional sensors helpless. A new type of north seeker has become a tool for technological innovation with its unique advantages. Today we’ll take a closer look at why it’s essential for jobs in these fields.

**Break through space limitations: special-shaped design for easy installation**

Traditional inclinometers and MWD systems are installed at a certain distance from the drill bit, causing measurement errors; The cylindrical north seeker ER-MNS-09 adopts a compact design of 120mm × Φ30mm and weighs ≤150g. It can be directly embedded in the drilling rig's probe pipe and installed close to the drill bit.

This design is particularly suitable for oil logging tools (such as gyro tools, HDD tools) and TBM, significantly reducing measurement errors.

**Industry-leading accuracy: 0.25°secψ north-seeking accuracy**

In magnetic mining areas or deep well environments, magnetic field interference often leads to azimuth measurement deviations. The north seeker achieves true north orientation based on a three-axis MEMS gyroscope and accelerometer, with an accuracy of up to 0.25°secψ (1σ), far exceeding similar products on the market (generally 0.5°~1°secψ). The measurement error of the azimuth is controlled within a very small range.

Attitude tracking can be performed: output pitch, roll, and azimuth data to provide adjustment basis for drilling rigs or mining equipment. Initial attitude calibration and true north orientation are automatically completed in 5 minutes, greatly shortening the deployment time.

**A reliable partner in harsh environments: shock resistance, wide temperature range, and long battery life**

The operating environment of the oil and mining industry is extreme. The high-temperature version of the north seeker has an operating temperature of 5~125℃, which is suitable for high-temperature environments in deep wells; it can withstand strong shocks and vibrations during drilling to ensure continuous and stable data; it only requires 2W power and supports 6~12V wide voltage input, which is suitable for long-term continuous operation.

**Why choose a cylindrical north finder? **

Technological breakthrough: breaking the monopoly, the performance is comparable to that of a fiber optic gyroscope, and the cost is reduced;

Customized service: providing different accuracy and different temperature versions, normal temperature version (5~55℃) and high temperature version (5~125℃), to adapt to different operational needs;

RTK signal is easily blocked? IMU makes RTK have unlimited possibilities

When you use an RTK surveying instrument to measure in some places with obstructions or requiring a large tilt, do you always encounter weak signals, no signals, or inaccurate measurements?

Now many RTKs are equipped with IMUs to make measurements more efficient and accurate. IMUs can maintain short-term relative positioning accuracy when RTK signals are blocked or temporarily ineffective. A separate external IMU can meet measurement needs more flexibly.

For example, an IMU ER-MIMU-12 can perfectly solve the above problems while improving measurement and stakeout efficiency!

**Excellent performance, automatic tilt compensation**

Equipped with a three-axis gyroscope and a three-axis accelerometer, the built-in gyroscope dynamic measurement range is ±400°/s, bias instability ≤1°/h, angle random walk <0.25°/√h; accelerometer dynamic The measurement range is ±30g and the bias stability is <50ug.

The IMU can be used to perform real-time interference-free and automatic tilt compensation on the RTK surveying instrument, and can perform measurements at large tilt angles. The IMU data is used to sense the device’s attitude changes (roll angle, pitch angle, and yaw angle) and perform tilt compensation.

It can ignore magnetic fields and can achieve accurate measurements even in difficult locations.

**Compact size, easy integration**

The 120mm x Φ30mm cylindrical IMU weighs ≤150g and is very portable.

In some measurement scenarios that require rapid deployment, the cylindrical IMU can be conveniently fixed on a tripod or measuring rod and can be put into use quickly without complicated debugging, saving time and costs.

**Quick initialization and accurate dynamic measurement**

RTK initialization time is long, IMU can significantly shorten the RTK initialization time. You can initialize the internal IMU by walking a few meters and easily start the measurement mode!

Even if the measuring rod is moved, tilted or leveled during measurement, there is no need for tedious calibration procedures and the measurement can be continued immediately while ensuring measurement accuracy.

IMU can make RTK measurement results more accurate, improve measurement efficiency, and expand the application scope of RTK surveying instruments, especially in environments with limited GNSS signals.
