摘　　要：中海油服自主研发的随钻测井系统Drilog~已进入商业化应用阶段。从随钻测井的深度跟踪基本原理与分布式系统架构入手,阐述了其深度跟踪子系统的关键技术。通过公式论证,研究了大钩高度和大钩载荷的测量原理和标定方法,分析了钩载滤波算法的优化方法。介绍了深度跟踪系统在测量手段改进、算法优化、系统设计优化等方面的工作,总结了该系统在现场的应用成果及未来发展方向。The Drilog LWD System which is proprietarily researched and developed by China Oil- field Services Limited had come into commercialization stage. Starting with the basic principle and distributed system architecture of depth tracking in LWD system,the key technology of the depth tracking subsystem is illustrated in this paper. Through formula study, the measurement of block height and hook load, and the calibration methods of related sensors are expounded, and the opti- mization of hook-load filtering algorithm is analyzed. The depth tracking system in measurement method improvement, algorithm optimization, and system design optimization are introduced as well, and the field application of the system and its future development direction are summarized.
