摘　　要：基于井水位微动态数据及井水化学特性分析,参考井水位对气压的阶跃响应函数方法、频谱分析方法、潮汐波群相位超前或滞后方法、水-岩平衡状态分析方法,提出了地震观测井地下水埋藏类型判定方法及综合判定依据,并将其应用于川滇地区地下水埋藏类型的综合判定。结果表明:根据本文判定方法得出的地震观测井的地下水埋藏类型,与依据成井时的贮存埋藏条件判别得到的观测井的地下水埋藏类型有很多不一致,并对此进行了讨论。On the basis of the micro-dynamic data of the water level and the analysis of hydro-chemical characteristics of the seismic observational well, and referring to the methods like the step response function of water level and air pressure, the spectral analysis, the leading or lagging of the phase of tidal wave group, and the water-rock equilibrium analysis, we propose a method of judging the groundwater type of the seismic observational well, and the synthetic judgment basis.Then we apply our method and judgment basis to judging the groundwater type in Sichuan-Yunnan region.We find that the groundwater types of seismic observational wells got according to our judgment method differ sharply from the ones judged according to the storage conditions at the time when the wells were built.Thus, we further discuss the reason.
