As a universal and high precision measurement tool, fiber optic gyroscopes (FOG) have been proved by many projects. Different precision gyros have different application fields. The theoretical basis of FOG is based on Sagnac effect. It has excellent anti-interference ability, high reliability, fast reaction rate, fast start-up time, and can run for a long time and high intensity.
The main principle of fiber optic gyroscope: when the beam is advancing in a light guide fiber ring, if the ring channel rotates, the time required for the light to advance along the direction of the channel rotation is more than the time required for the opposite direction along the channel rotation, and the phase difference of the optical path is detected by the change of the optical path or the change of the interference fringe to measure the rotation angular speed of the optical path.
In recent years, there are different types of gyro inclinometer in the market, most of them use mechanical gyro, which has poor vibration resistance and shock resistance, and is easy to be damaged in the harsh environment of oil drilling. Because the measuring method of mechanical gyro inclinometer is fixed point measurement, the attitude value can not be calculated in real time during the movement, so it is difficult to reflect the actual well trajectory, and the logging efficiency is greatly reduced. The FOG is an all-solid optical gyroscope, without rotating and frictional parts, and has the advantages of continuous measurement and adaptability to harsh mechanical environment. The fiber optic gyro continuous inclinometer with fiber optic gyroscope as the core component is mainly used to measure the trajectory of casing well and determine the plan of re-exploration and exploitation. In casing detection and directional perforation, the instrument azimuth value is determined. The conventional magnetic orientation instrument cannot achieve the above function requirements because of the magnetic shielding of casing. Fiber optic gyro continuous inclinometer is a kind of self-oriented instrument based on inertial measurement technology, which is high precision, resistant to shock and vibration, and not affected by magnetic field.
