基于开采性抽水试验的大汶口盆地地下水资源分析

摘要

According to the exploitable pumping test in the northeast of Dawenkou basin, groundwater level changes of water source wells and observation wells around the region were analysed. It shows that the exploitable pumping test influences the aquifer of Paleogene fracture water remarkably. Water in water source wells comes mainly from the aquifer of Paleogene fracture water, and has certain hydraulic connection with Quaternary pore water. Through the analysis of the Dawenkon basin's exploiting capacity,the existing issues of environmental hydrogeology are put forward.%根据大汶口盆地东北部抽水试验资料,分析了水源井与周边区域观测井地下水水位变化情况.结果表明,开采性抽水试验对古近系裂隙水含水层影响最为明显,水源井中的水主要来源于古近系裂隙水含水层,并与第四系孔隙水存在一定的水力联系.通过对大汶口盆地的开采潜力进行分析,提出了研究区存在的环境水文地质问题.
