摘　　要：本文给出了AR模型功率谱估计Burg递推算法及在钻柱振动检测及解释技术的应用,通过钻具振动波的测量和功率谱分析,可以总结出各种工况和故障下各功率谱估计的规律,结合人工神经网络系统,达到预测钻井事故,及时排除故障和对地层岩性的辅助解释的目的。The paper presents a Burg algorithm based on autoregressive spectrum es- timation and its application in drill string vibration analysis. The method can give various characteristics of downhole complex events combined with artificial neural net system through the measurement and spectrum analysis of drill string vibration waves.
