Previous Gyroscope Inclinometer main measurement unit consists by flexible dynamically tuned gyro sensor and acceleration sensor. Because the flexible dynamically tuned gyro sensor has complex structure, so the gyro inclinometer’s shockproof performance is not good and take longer time for positioning and It is difficult to guarantee the measuring accuracy in high- inclination well. TLX50-200D optical fiber gyro inclinometer uses optical gyro sensor for measurement,with good shockproof performance, high-accuracy and high reliability and fast north seaking. Optical fiber gyro inclinometer is suitable for the bad field environment, borehole trajectory measurement, directional drilling measurement and oriented perforating.Such optical fiber gyro inclinometer also can work with other cased hole logging tools of Sitan.
