摘要:
应用高密度电法开展河南省巩义市应急抗旱找水打井工作,发现巩义市东南部基岩山区深部含水层的电阻率为低阻,基岩电阻率总体为高阻; 西北部松散层的上部黄土电阻率为低阻,下部砂砾石松散含水层电阻率为高阻,从而提出了在该地区应用高密度电法勘查找水的新思路,即“基岩山区高阻中寻找低阻”和“松散层低阻中寻找高阻”。在巩义市打井20口,成井率100%,实践证明该思路是行之有效的。在应急抗旱找水打井工作中,在快速熟悉区域地质、构造和水文地质条件的基础上,开展多种物探方法(高密度电法、电测深、测井等)相互验证十分重要,可为在应急早期尽快统一认识、确定具体井位和避免打“干眼”提供重要技术支撑。应急抗旱找水打井工作通常时间紧、任务重,为确保完成应急任务,应根据应急找水任务工作量、应急时间和当地不同的水文地质条件,合理安排不同的钻探机械和钻井方式。
Abstract:
Groundwater exploration and drilling work for emergency drought were carried out using high-density resistivity method in the city of Gongyi, Henan Province. The results show that deep aquifers and bed rocks in mountain area of southeastern Gongyi are characterized by low and high resistivity, respectively; while upper loess and lower gravel aquifers in northwestern area are characterized by low and high resistivity, respectively. Thus, a new idea for groundwater exploration by high-density resistivity method in study area was proposed, i.e. focusing on low resistivity part in high resistivity mountain area and high resistivity part in low resistivity loose sediments. 20 drilling wells are successfully completed in the city of Gongyi, which has proved to be effective. At the same time, quick understanding local geology, structure and hydrogeology conditions is vital to carrying out multiple-method geophysical exploration(such as high-density resistivity, electrical sounding and well logging)to mutual verification of groundwater exploration and drilling work for emergency droughts. Therefore, an early quick consensus can provide an important technical support for how to position well drilling positions and avoid appearance of dry wells. Emergency drought relief is characteristic of tight schedule time and heavy work. In order to ensure the completion of emergency task, the paper also points out that different drilling machinery and modes should be reasonably allocated according to workload of groundwater exploration, emergency response time and local hydrogeological conditions.
