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.

What is the biggest difference between Gyro Northfinder and gyro compass?

 North finder is a high-precision dual-shaft dynamic tuning gyro that can determine the true north direction value of the attached carrier by measuring the angular velocity of the earth's rotation. It is not affected by external magnetic fields or other environments. In addition, it can also be combined with acceleration for horizontal angle measurement and correction. The gyro north finder is mainly used for: radar, antennas, military vehicles, initial alignment and direction control.

The compass is a simple instrument used to determine the orientation. The main component is a magnetic needle that can be freely rotated on the shaft. The magnetic needle can be maintained in the tangential direction of the magnetic meridian under the action of the earth magnetic field. The north pole of the magnetic needle points to the geographic North, and this property can be used to identify the direction. It is commonly used in navigation, geodesy, travel and military affairs.

Since the structures and principles of the two types of gyro north-finding systems are different, they each have their own strengths. Therefore, based on the respective characteristics of these two types of devices, solutions can be complemented during research or use.

For example , MEMS north seeker(north finder) ER-MNS-06 (0.25°-1°) is our Smallest Size Triaxial MEMS North Seeker(north finder),and can be used in different areas where need small size north seeker(north finder).

Classification of North Finder

 

North finder is a compass, is used to find the north direction at a position value. Gyro north finder, also known as gyrocompass, is an inertial measurement system based on the principle of gyroscope to determine the earth’s rotation rate in the horizontal projection direction of the earth. Its north seeking process does not require external reference. In addition to the high latitude limit, it is not affected by weather, day and night, geomagnetic field and site pass conditions. Gyroscope is a kind of precision inertial measurement instrument, which is used to provide directional reference for artillery, surface-to-surface missile and ground radar and other mobile weapon systems.According to the type of gyro used, gyro finder can be divided into the following three types:

1.A north seeker with two degrees of freedom gyroscope as a earth rotation sensor (such as hanging pendulum gyro    north seeker)

2.A north seeker with a uniaxial rate gyroscope as a sensor (such as a strapdown gyro north finder)

3.Platform north seeking system

Fiber optic gyroscope is a kind of high precision inertial instrument, which can be used to indicate the orientation of the carrier and the true north direction.Use of fiber optic gyroscope measured rate of the earth from the Angle of value and the measured gyroscope and accelerometer horizontal plane Angle, through the computer solution can be obtained in the baseline and the true north direction Angle, placed on the baseline of the accelerometer find north finder attitude Angle can be detected.
