摘　　要：针对SDZ-3070连斜微球短节在测井中出现倾角方位精度不达标的现象,从校验期限、加速度计输出值是否达到标量、磁通门传感器对称性、以及线路磁化四个方面进行讨论并提出了可行的提高精度的方法。Aiming at the problem that tile azimuth angle of SDZ-3070 integrated unit can＇t meet the required accuracy, the diseussinn is made on four aspects which include the calibration period, the output value of the gravity aeeelerometer, symmetry of the flux gate sensor, and the anti - magnetization of the flux gale sensor. A feasible method for improving the accuracy is put forward.
