摘　　要：介绍了基于动力调谐式挠性速率陀螺的捷联式惯性测向系统的构成、工作原理及特点。该系统采用惯性测量组件直接固连在载体上,通过建立捷联数学模型完成惯性导航数据的解算,进而确定空间某点方位,可用于开窗侧钻井、定向井和水平井导向、井身轨迹测量、定向射孔、丛式井组复合导向等工程。与传统的磁方位测量方法和框架式陀螺测量系统的比较结果表明,该系统克服了磁方位测量方法在套管、钻杆、油管以及在磁干扰地层中测定方位时存在的问题,其测量精度优于框架陀螺系统。给出了丛式井组定向作业、井身轨迹测量方面2个应用实例。A strap-down inertial surveying system （SISS） based on a dynamically tuned gyroscope （DTG） is introduced. The principle and characteristics of the SISS are discussed. Comparison of the SISS with the others shows that the SISS solved the problem of conventional magnetic azi- muthal surveying method in ferromagnetic casing, tubing, drill stem or magnetic formation, and its measurement precision is better than that of frame gyroscopes surveying system. The SISS might be used in petroleum engineering of sidetrack drilling, geo-steering of directional or horizontal drilling, bore-hole trajectory tracing, directional perforation, and compounding steering of cluster wells. 2 case studies of the SISS in cluster wells directional operation and bore-hole trajectory tracing are presented.
