Framework-correction type inclination-angle and azimuth-angle logging unit

The utility model relates to a framework-correction type inclination-angle and azimuth-angle logging unit which comprises accelerometers, fluxgates and a circuit board, wherein the accelerometer Ax, the accelerometer Ay and the accelerometer Az form an accelerometer three-dimensional coordinate system, the accelerometer Az is vertical downwards along the Z direction, the accelerometer Ax faces towards the X direction, and the accelerometer Ay faces towards the Y direction; the fluxgate Mx, the fluxgate My and the fluxgate Mz form a fluxgate three-dimensional coordinate system, wherein the fluxgate Mz is vertical downwards along the Z direction, the fluxgate Mx faces towards the X direction, and the fluxgate My faces towards the Y direction; the accelerometer Az and the fluxgate Mz are in the same direction, the accelerometer Ax and the fluxgate Mx are in the same direction, the accelerometer Ay and the fluxgate My are in the same direction, and two groups of sensors are separated by the circuit board; after three times of rotation, a first-time rotation angle decides an azimuth angle, a second-time rotation angle decides an inclination angle, a third-time rotation angle is a tool facial angle, and the measuring precision of the framework-correction type inclination-angle and azimuth-angle logging unit is plus or minus 0.2 degree.
