太平庄观测井地下流体动态综合研究

太平庄观测井是一口有十几年观测资料并有几次较好震例的综合观测井。近年来 ,由于地下水的大量开采 ,使得地下水位大幅度下降 ,尤其是观测井周围地热的开采 ,对太平庄观测井的正常动态影响较大。文中结合往年较正常的动态特征和地质构造等 ,分析了太平庄观测井的水位、水温、逸出气和断层气等的年动态变化特征。结果表明 :水位、水温的变化规律受观测井水位补给区降雨量的影响 ,水温还受当地降雨量的影响 ,特别是太平庄观测井周围新井的抽水对水温、水位、逸出气均有一定影响。由于观测井受诸多因素的影响 ,导致太平庄观测井的观测资料不能按往年的变化规律进行动态分析。在排除了降雨和人为的干扰因素外 ,太平庄观测井的资料动态趋势还可用于首都圈的震情预测

SYNTHETIC STUDY OF THE DYNAMIC BEHAVIOR OF UNDERGROND FLUID IN TAIPINGZHUANG WELL

Taipingzhuang observation well is one of the wells that has been observed for over ten years and has experienced some earthquake cases.In recent years,the ground water level has significantly fallen due tolarge amount exploitation of underground water,and especially geothermal exploitation around the Taip-ingzhuang observation well.This paper presents the analysis of the annual behavior of water level,water temperature,escaped gases and fault gases of the Taipingzhuang observation well,on the basis of the n
