| 摘 要： | 鲁西南(中西部)地区普遍存在地下水中氟化物及矿化度含量较高的问题。电阻率与地下水矿化度关系密切,高氟又易与高矿化度伴生存在,因此赋存高矿化度地下水的黏土层与赋存可饮用地下水砂土层电性上的差异为利用电法在该地区勘查出可饮用地下水提供了基础条件。综合区内区域地质、水文地质及地球物理特征,对重点区的电测深曲线进行了精细的定性及定量解释,划分出重点区内含水层的埋深、黏土层及砂土层分界线,推断出了深层高阻层主要为含淡水砂土层。根据物探推断成果在牡丹区沙土集及曹县常乐集重点区分别施工了2眼钻井。结果表明,钻井出水量丰富,水质较周边有明显改善,直流电测深是在该区域寻找可饮用水资源的一种经济、有效的勘查手段。

| Abstract: | High content of fluoride and mineralization in groundwater is a common problem in southwestern Shandong province. Resistivity is closely related to the mineralization of groundwater, and high fluorine is easy to coexist with high mineralization. Therefore, the difference in electrical properties between clay layer with high mineralized groundwater and sandy layer with potable can provide basic condition for exploring potable groundwater in this area by using electrical method. Based on regional geology, hydrogeology and geophysical characteristics, the electric sounding curves in key areas are interpreted qualitatively and quantitatively in detail, and the buried depth of aquifers, clay layer and sand layer boundary in key areas are divided. It is inferred that the deep high resistivity layer is mainly fresh water sandy layer. According to the results of geophysical prospecting, two drilling holes are constructed in Shatuji town in Mudan district and Changleji town in Caoxian county. It is showed that the drilling water output is abundant and the water quality is significantly improved compared with the surrounding areas. Direct current resistivity sounding is an economic and effective exploration method for searching for potable water resources in this area. |
