针对陀螺测斜仪系统在小角度井斜角测量时存在测量精度低的问题，对其产生机理和形成原因作了详细分析，并推导了新的小角度井斜角测量的姿态提取方法。搭建基于高精度动调陀螺的随钻测斜仪产品原理样机，并利用高精度三轴转台反复多次模拟实际钻井施工中随钻测井过程，结果表明该方法可有效的提高陀螺测斜仪小角度井斜角随钻测量的解算精度。

According to the fact that the small angle of inclination measurement exists in low accuracy measurement of gyro inclinometer system. The generation mechanism and formation cause were analyzed in detail, and a new extraction method was deduced to suited to the measurement of the small angles of inclination of attitude. The MWD product prototype was built based on dynamic and high precision of tuned Gyro,and the use of high precision of three axes turntable table repeatedly simulated the actual drilling logging process to the drill processing. Experimental results show that this method can effectively improves accuracy of gyro inclinometer at the measurement of small angles of inclination.
