断层气观测网的建设目标是在一次破坏性地震发生前捕捉到一定数量的源兆异常,探索地震短临预测的新途径,显著提升中国地震预测能力。该网应集中布设在主要地震活动区(带)中未来二三十年内有可能发生破坏性地震的地区,网的规模依地震危险区的大小而定;观测点应选在活动断裂带上,尤其选在其上盘或活动主动盘上,观测点的密度以捕捉到源兆为目标,依可能发生的地震震级而定;观测点的选址与观测孔的建设应结合当地地质与水文地质条件而定;观测项目以H2,CO2,Rn与Hg为主,且应以H2为首选;观测模式以定点连续观测与定点定时流动观测相结合,提倡一孔多项观测。

东郭井是山西省南部地区映震性能较好的一口流体观测井.2011年4月东郭井井孔发生错位,之后出现的异常形态与井孔错位前有所不同.本文通过对比东郭井井孔结构改变前后其对气压效应、固体潮效应等地下水微动态的响应能力;计算井管错位前后井-含水层特征参数;分析影响东郭井水位动态的主导因素,研究已改变的参数对水位微动态的影响程度和大小.根据东郭井2011年4月井管错位前后气压系数、潮汐因子及井一含水层系统特征
鲁甸地震产生的水位同震残留阶升的井为团2井,位于翼子坝断层上,而这次永善地震却没有发生在翼子坝断裂上,而是发生在未发生在千万贯井附近的峨边-金阳断裂的一条北西向分支断裂的延长线上。并且鲁甸地震时千万贯井的同震变化为脉冲状的陡升陡降型,并且震后恢复到震前水平。依此看来,不能简单地凭借震后效应时的水位残留阶升区,判断为未来发震的危险区。
