Fiber-Optic Gyro Inclinometer
Using fiber-optic gyroscope and accelerometer as the main inertial sensor of multipoint gyro,the main characteristic of fiber-optic inclinometer is with strong impact resistance and durability. It can be used in retesting of the wellbore trajectory, side drilling, borehole survey of directional well.
