Calibration method for high-precision spot-measurement gyro inclinometer for well drilling

The present invention discloses a method for calibrating precision drilling point where the gyroscopic instrument, comprising the steps of: (1), the two degrees of freedom with two flexible quartz gyros and three accelerometers fixed inclinometer in the three-axis turntable, triaxial gyro inclinometer constituting right-handed coordinate system, wherein two axes X and Y axes held horizontal, a third Z axis perpendicular to the ground; (2), an eight-position calibration, record the voltage signal output from the gyro inclinometer; (3), each voltage signal into equation: solving the calibration parameters gyroscope inclinometer. The present invention utilizes eight position measurement point, greatly simplifies the testing process, data is automatically read and saved, the operation is simple, the calculation process is performed by the computer; the test method is designed in eight-point position of a reliable calibration method inclinometer , reliability and practicality, greater efficiency and accuracy.
