摘　　要：利用钻井过程中的各种信息及时发现钻井异常情况,预防钻井事故的发生是降低钻井成本、提高钻井经济效益的重要途径。以综合录井信息为基础,利用钻井过程中动态参数的变化特征和时间序列的数学描述方法,对钻井过程中出现的故障进行识别与诊断,并开发了相应的诊断软件。现场应用表明,该诊断软件具有较高的在线监测与识别故障的能力。It is a very important way to decreasing drilling costs by finding the abnormal conditions while drilling and preventing drilling defaults occurrence using drilling information. Using the theory of fault detection and diagnosis, in the paper, the signals changing characters under all fault conditions during drilling process were analyzed based on mud logging system. The describing method of dynamic signals and the on-line fault diagnosis methods were given out. The on-line drilling fault detection and diagnosis software was developed.
