摘　　要：针对地下钻进的特殊要求,描述了一种定向钻进姿态测量系统,对系统具体的结构以及姿态解算方法同时进行了详细说明。该系统采用新型微硅加速度计和磁阻式磁强计作为姿态敏感器件,实时获取定向钻进中钻具的方位角、倾角和面向角信息。此系统具有体积小、成本低、可靠性高等一系列优点,非常适合地下钻进测量。An attitude determination system for underground directional drilling is described in this paper. The configuration of the system and the method of attitude calculation are given in detail. The system, which adopts 3-axis micromachined polysilicon accelerometer and 3-axis magnetoresistive magnetometer as its attitude sensors, can get pitch, roll and azimuth information in real-time while drilling. The system has the advantages of small size, low cost, and high reliability. It is especially suitable for directional drilling to obtain the attitude angles.
