摘　　要：介绍了格尔木流体观测井及数字化仪器的基本情况,对数字化观测资料进行了初步分析,并分析了格尔木周边3次6级以上地震前的异常特征,结果显示:同一方法提取的异常在不同地震前差别较大,且异常可能与区域构造相关。对于该观测井不同测项,震前的异常差异也较大。Abstract：The basic situation of Golmud fluid well and digitalization instruments are introduced, and the digi- tal data and the anomalous characteristics of three earthquakes with Ms≥6. 0 near Golmud are analyzed, the results show that the anomalies are quite different before different earthquakes, and they may be related to re- gional tectonics. The amonalies of other observation items in the well are also quite different.
