盘锦一号井气体观测映震规律探讨

摘要

The obviously abnormality of solution gas in No.1 Panjin well was observed almost a month before the earthquake occurred on 29 November 1999 in Xiuyan. We observed a mass of hydrogen before the earthquake what generally very little can be observed. The abnormality of hydrogen was a month or so prior the earthquake, keeping pace with small earthquakes activities in epicenter. All of the basic content of an exception were positive. The author studied the abnormality of solution gas in No.1 Panjin well before the earthquake occurred on 29 November 1999 in Xiuyan. Summed up the rule of reflect earthquake of solution gas in No.1 Panjin well.%盘锦一号井溶解气在1999年11月29日岫岩5．6级地震前近一个月，出现了明显的短临异常。在震前观测到大量氢气，而平时很少能观测到的氢气。异常出现的时间一般一个月左右，与震中小震活动增强时间基本同步，均为含量上升的正异常。本文针对对气体在1999年11月29日岫岩5．4级地震前异常做了一些探讨，总结了盘锦一号井气体观测的映震规律。
