磁针式测斜仪是目前被广泛采用的钻孔弯曲度测量仪器。仪器的主要部分是探管(井下部分),它几乎是全部由机械部件组装而成的。由于长期使用、长途搬运或经较大的碰撞、震动等原因,都有可能造成机械部件的磨损、松动、传动件变位失灵,转动件失衡而不能保持水平等故障。在野外条件下,如何检查,鉴定探管及其部件的轻度变化,如同心度、水平面、灵敏系统的重心、以及转 Magnetic pin inclinometer is currently widely used drilling curvature measurement instruments. The main part of the instrument is the probe (downhole section), which is almost entirely assembled from mechanical components. Due to long-term use, long-distance handling or by a larger collision, vibration and other reasons, are likely to cause mechanical parts wear and tear, loose transmission parts failure, rotating parts unbalanced and can not maintain the level of failure. In field conditions, how to check and identify minor changes in the probe and its components, such as concentricity, water level, the center of gravity of the sensitive system,
