摘　　要：简要介绍了速率陀螺测斜仪的结构特点、测量原理、技术指标及优点,详细介绍了速率陀螺测斜仪在海洋CDX井组表层套管的井眼轨迹测量和表层套管内定向绕障中的应用及其注意事项。现场应用表明,速率陀螺测斜仪测量精度高,能在磁干扰的情况下,精确定向。This paper introduces briefly the general situations of rate gyroscope, the structures, working principles, advantages and specifications. Several field applications of rate gyroscope in such aspects as wellpath measurements, directional drilling in surface casing and corresponding considerations to CDX multicluster wells are mainly discussed. Field applications show that the rate gyroscope can orient precisely under magnetic interference. 
