【摘要】 本文系统清理、分析了天津地区的咸水井观测资料,通过实际观测资料分析认为,天津地区的咸水体具有封闭性好,不开采的优势,具备了作为地震观测井的基本条件;在观测资料的动态方面,一般具有两种动态变化特征,但仅个别井能够记录到微弱固体潮信息,同时也不能记录到水震波;在映震方面,取得了一批震例资料,其异常幅度往往较大,映震特征明显;在观测层的选取上,一般应选择50 m以下的咸水层,并且在观测段中最好应包括海相层;在观测点的位置方面,应选择较大断裂的交汇点、拐点以及端点部位或活动性较强的断裂上。更多还原

【Abstract】 In this paper,observation data of salt water wells in Tianjin region are systematically analyzed.Through the analysis of actual observation data,the results show that the salt water layer possesses the advantageous position of better closure and non-exploitation,so it possesses fundamental conditions as observation well for earthquakes;In the aspect of dynamic variation,observation data usually possess two dynamic variation features,but only individual wells show a weak response of solid earth tide,at the same time it cannot record coseismic reflection;In the aspect of reflecting earthquakes,some earthquake examples are obtained,and the anomalous range usually is large,the feature of reflecting earthquakes is very clear;As for the selection of observation layer,it is better to select observation layer under 50 m,moreover the observation layer may include marine layer as well.The position of observation sites should be the interjunction of large scale faults or the inflection point or end point of faulting as well as on fairly active faults.更多还原
