Gyro
inclinometer is mainly designed for drilling inclination and
azimuth measurement of in iron casing in magnetic mine areas.
General inclinometer drilling azimuth mainly relies on compass or
magneto sensor for orientation; in the magnetic mine area or inside
iron casing, due to the effect of magnetic substance, it is
difficult to accurately determine the orientation of drilling.
Therefore, the most effective way to measure azimuth in strong
magnetic environment is to utilize gyro direction method without
magnetic interference. Gyroscopes have two categories: mechanical
type and electronic type. Mechanical gyroscope has greater zero
drift, but short service life, high price. Gyro inclinometer adopts
electronic gyroscope, it has advantages like small size, long
service life, less zero drift, lower price, etc.
Gyro
inclinometer consists of three parts namely ground instrument,
winch (winch controller is required when＞**0m),
downhole probe, with measured data automatic storage, compact
instrument size, and simplicity of operation.
