Applications
The Gyro North-seeking Wired Measurement While Drilling System breaks through the traditional method of azimuth measurement relying on the Earth's magnetic field. It successfully gets rid of the need for a magnetic - free drilling tool protection environment. Relying on the communication and power supply of high - power long - distance directional drilling rigs through cable - passing drill pipes, it is not affected by magnetic interference. It can be widely used in measurements in magnetically - interfered environments, enabling drilling in metal ore strata, re - measuring the trajectories of old wellbores in casings, casing window - opening, and sidetracking operations. Its north - seeking principle is to calculate the angle between the sensitive axis and the actual direction by using the projection of the angular velocity of the Earth's rotation on the horizontal direction along the gyro north - seeking sensitive axis and the algorithm corresponding to the north - seeking scheme. This angle value is the north - direction value.
Product Features
It can monitor multiple data in real - time, including inclination angle, azimuth angle, tool face angle, total magnetic field, total gravitational acceleration, and signal strength.
It is not affected by magnetic interference and does not require traditional magnetic - free protection.
It has a short size, small volume, and light weight.
The post - maintenance cost is low.
It has a long service life, high measurement accuracy, and short north - seeking time.
It has stronger resistance to temperature, vibration, and impact, and is stable and reliable in operation.
There is no limit to the working duration, and it does not need to be calibrated regularly.
