| 摘 要： | 为提升对山西省地下流体观测井承压性的进一步认识，以位于该省北、中、南部的朔州井、静乐井、祁县井、洪洞井和东郭井为研究对象，选取水位、气压观测数据，并利用井水位的理论固体潮数据，分别对井水位进行气压的阶跃响应函数计算、FFT频谱和潮汐相位响应分析，综合判定地下流体观测井—含水层类型，结果表明，5口观测井地下水埋藏类型均为半承压水。

| Abstract: | In order to improve the further understanding of the pressure bearing capacity of underground fluid observation wells in Shanxi Province, this study takes five observation wells (Shuozhou, Jingle, Qixian, Hongdong and Dongguo) that are located in the north, middle and south of the province as the research objects. The pressure observation data and the theoretical solid tide data of the well water level are used to calculate the step response function of the well water level to the pressure, the FFT spectrum of the water level data, and the tidal phase response analysis to comprehensively determine the underground fluid well-aquifer type. It shows that the groundwater burial types of the five observation wells are all semi-confined water. |
