Is there an error in drilling trajectory control? The north finder installed near the drill bit makes drilling more accurate!

 Directional well technology is one of the most advanced drilling technologies today. Based on actual cases, the main problem of directional wells is the control accuracy of the trajectory. The directional tool will deviate from the trajectory and the measurement error is large. There is also a trajectory prediction error caused by the MWD being a certain distance away from the drill bit.

We have developed a new cylindrical north seeker ER-MNS-09 to address these problems, which can be installed close to the drill bit and directly in the drilling rig’s exploration pipe. It can be used in gyro tools or HDD tools.

**Near-drill-bit installation**

This is an aluminum alloy cylindrical MEMS north finder, 120mm long and only 30mm in diameter, light in weight and with good thermal conductivity. It can be directly installed near the drill bit or in the drill rig probe, and can independently measure the azimuth and attitude angles, more accurately control the well trajectory and reduce errors.

**High-precision north-seeking orientation**

The north-seeking accuracy of this north finder can reach 0.5°secψ(1σ), which can provide more accurate azimuth information. This is crucial for drilling operations that require precise orientation. At the same time, it is not affected by magnetic interference and can also be used in magnetic mining areas.

**Self-alignment and attitude tracking function**

After startup, it can automatically initialize alignment and then automatically determine the true north direction. No manual alignment is required, and the north-seeking time only takes 5 minutes. It can also track and provide attitude information to ensure that the drilling trajectory meets the design requirements.

**Adapt to harsh environment**

During the drilling process, there will be strong impact and vibration. It can resist high impact vibration and ensure stable operation. There is also a high temperature version with an operating temperature range of 5°C~+125°C. The low power consumption design of only 2W ensures stable output under continuous working conditions.

This north finder is designed to be more suitable for applications such as oil mining and drilling, especially in situations where precise control is required.

Why is this north Seeker your best choice in the drilling field?

 

During downhole operations, the main problems that the north seeking system needs to solve include impact vibration, system volume, azimuth accuracy, and downhole temperature. Considering the measurement requirements at a certain depth, the north seeker needs to be equipped with an efficient thermos bottle. The fiber optic north seeker is expensive, and its volume increases with the increase in accuracy, which greatly limits the drilling and logging equipment. In general, the north seeker needs to be installed on the guide rail of the drilling rig or on a stable plane during drilling. At the same time, it is necessary to ensure that the axis of the north seeker is consistent with the axis of the drilling rig.

But with ERICCO's MEMS North Seeker (ER-MNS-09), these problems can be easily solved. Why should we choose it?

1. New appearance, high precision: The new cylindrical north seeker tailored for this field has a diameter of only 30mm, a small size, and is easy to install in a thermos bottle, meeting the application requirements of ordinary standard cased wells, drill pipes and small well diameters.

2. Different installation positions: The special shape enables it to be placed in the probe of the drilling rig, which is more accurate than other north seekers. It can provide strong support for users to solve information such as azimuth and attitude angle. It helps drilling engineers to accurately control the trajectory of the drill bit and ensure that the drilling operation is carried out in the predetermined direction.

3. Different accuracy for you to choose: There are three models in this series (ER-MNS-09A, ER-MNS-09B, ER-MNS-09C) with north seeking accuracy of 1°secψ(1σ), 0.5°secψ(1σ), and 0.25°secψ(1σ) respectively, which can be selected according to different needs.

4. Strong and durable, resistant to high impact and vibration.

5. Adopting MEMS technology, the cost is lower, but the high performance is not compromised.

Efficient mining: MEMS IMU unlocks new possibilities for oil and mining

     

    Oil and coal are important basic energy sources. With the rapid development of science and technology, MEMS IMU is increasingly widely used in the fields of oil and mining, injecting new vitality into this traditional industry. Oil and mining are complex and arduous tasks, facing many challenges. Most of these resources are distributed in areas with complex geological conditions. As resources are gradually depleted, the difficulty of exploration and mining continues to increase, which puts higher requirements on exploration and mining equipment.

In response to these problems, ERICCO has developed a new MEMS IMU ER-MIMU-09 specifically for the oil and mining field, which is mainly used in gyroscope tools and directional drilling tools. There are four versions in this series (ER-MIMU-09A, ER-MIMU-09B, ER-MIMU-09C, ER-MIMU-09H), with different accuracy and working temperature, which can be selected according to needs.

New appearance, small size

This IMU is designed for drilling rigs. It adopts a cylindrical shape with a diameter of only 30mm. It can be easily used in the probe tube, meeting the needs of users with higher requirements for tool tube diameters and providing convenience for limited working spaces.

High precision, high performance

Equipped with high-performance three-axis MEMS gyroscope and three-axis accelerometer, the small size does not compromise performance. The built-in gyroscope bias instability is 0.01-0.02deg/hr, and the angular velocity random walk is 0.0025-0.025°/√h. The accelerometer bias stability is ≤0.05mg, and the bias repeatability is ≤0.1mg. It can accurately output angular rate and acceleration information to help drilling engineers accurately control the trajectory of the drill bit and improve operating efficiency.

Strong environmental adaptability

This IMU adopts MEMS technology. In addition to low power consumption, it has good shock and vibration resistance and is not affected by magnetic fields. Considering the special operating environment in the field of oil mining, general IMUs cannot accurately output information in high temperature environments. We divide this IMU into normal temperature version (ER-MIMU-09A, ER-MIMU-09B, ER-MIMU-09C) and high temperature version (ER-MIMU-09H). The normal temperature version has an operating temperature of -40℃~ +80℃, and the high temperature version has an operating temperature of -40℃~ +125℃. It can work continuously in high temperature and harsh environments.
