摘　　要：通过计算聊古1井1981年1月至2007年10月氮气、氦气含量的比值(以下均写做N2/He),对N2/He进行低通滤波处理,提取有价值的地震异常信息,发现N2/He的异常变化与区域(指距本井300km以内)中强地震有着良好的对应关系。本文分析了N2/He异常变化与地震的关系,给出了发生中强地震的N2/He异常指标,探讨了其映震机理。The ratio of nitrogen and helium （N2/He） in Liaogu- 1 Well from January 1981 to October 2007 is calculated. After low-pass filtering, we found that the anomalies of N2/He were corresponding well with regional medium and strong earthquakes. The relationship between the variation of anomalies and earthquakes is analyzed, and the indexes of anomalies are presented. The mechanism to reflect earthquakes is also discussed.
