Abstract:
Water inflow , water quality and other parameters of several aquifers with a buried depth of 24 0 m and a thickness of 660 m for large thickness aquifers. Based on borehole core and logging data, the well is divided into 6 pumping section. The results showed that : the average hydraulic conductivity of the Luo he and Huanhe aquifer is lower than that in the upper section in the study area, there is a lmo st no hy draulic connectio n betw een the upper and lower aquifers of the same aquifer group, the upper of the Luo he a quifer is rich in high-quality freshwater resources, which can be used as a target mining layer for urban concentr ated water sources, and simultaneously prevent over-exploitation and lead to poor water quality, the stratified pum ping test with new packer technology may effectively solve the difficulty of obtaining hydrogeological parameters of larget hickness aquifers, which not only improve the a ccur acy of the survey but also obtain accurate and reliable hydrogeological parameters. Therefore, it is of great significance to clarify the flow relationship between aquifers and to rationally plan the exploitation and utilization of groundwater.
