Main characteristics：Main features: Three-axis fiber optic gyro well trace continuous measuring instrument is specially designed for measuring borehole inclination and azimuth, which can be used for measuring borehole inclination and azimuth not only in general borehole azimuth and inclination, but also in magnetic mining area and iron casing (ordinary inclinometer in magnetic mining area or iron casing is difficult to accurately determine borehole azimuth due to the influence of magnetic body). This product is a continuous well trace measuring instrument, which adopts fiber optic gyro, which is a small-caliber fiber optic gyro azimuth measuring instrument specially suitable for the field of inclination measurement.
Product Introduction
The three-axis fiber optic gyroscope continuous measurement instrument is designed specifically for measuring the inclination and orientation of drilling holes. In addition to measuring the azimuth and inclination angles of general drilling holes, it can also measure the inclination and orientation of drilling holes in magnetic mining areas and iron casing (ordinary inclinometers are difficult to accurately determine the orientation of drilling holes in magnetic mining areas or iron casing due to the influence of magnetic materials). This product's well trace continuous measuring instrument adopts fiber optic gyroscope, which is a small aperture fiber optic gyroscope azimuth measuring instrument specifically suitable for the field of inclinometer measurement.
The instrument adopts a newly developed small aperture precision three-axis integrated fiber optic gyroscope and three quartz accelerometers as the core sensitive units, which measure the angular velocity and acceleration of the instrument during the movement along the wellbore in real time. The three-dimensional attitude calculation is carried out through a solution processor to obtain real-time parameters such as wellbore inclination angle, wellbore inclination azimuth angle, perforation azimuth angle, tool face angle, and standard plate azimuth angle of the wellbore direction. Due to the limitations of small aperture and measurement environment, in order to overcome the impact of high temperature and harsh environment on the measurement accuracy of the instrument, the instrument adopts a scheme of installing thermos bottles, inserting heat absorbing materials, strong tracking Kalman filtering, and using wavelet neural networks for temperature drift identification and compensation of sensors. This system can effectively solve the problem of continuous measurement and curve recording of wellbore trajectories in environments without magnetic or magnetic interference. Its full attitude measurement characteristics make it also suitable for horizontal well measurement and have broad application prospects. The instrument has the advantages of small size, high reliability, long service life, high accuracy, small zero drift, shock and vibration resistance, low power consumption, and low price.
