| 摘 要： | 介绍了青海地区十个数字化水温井、六个数字化地温井的水温(地温)观测概况。经研究发现,2008年汶川MS8.0地震前,乐都和民和两个井孔出现了中期趋势异常,西宁、乐都和德令哈三个井孔出现了短临异常;从地域来看,异常测点主要集中于西宁-民和断陷盆地内,该区域其它两个正常运行的井孔没有异常,可能和探头与密闭套管末端间的距离过大有关。另外,笔者认为,西宁、乐都、民和井所表现出的中期和短临异常,可能与汶川地震的孕震过程密切相关。

| Abstract: | The temperature observation survey of ten digital water temperature wells and six underground temperature wells in Qinghai is introduced.It has found: middle-term anomalies in two wells in Ledu and Minhe,short-term anomalies in three wells in Xining,Ledu and Delingha;the anomaly areas were mainly along the Xining-Minhe fault line,two wells in the region worked with no anomalis,which might result from the long distance between the probe and the end of the pipe line.The authors believe the middle-term and sho... |
