高密度电阻率法在山东泰安地区抗旱打井工程中的应用

Application of High-density Resistivity Method in Drought Drilling in Tai'an Area of Shandong Province

摘要:

山东省泰安地区地下水类型主要为松散类孔隙水、变质岩火成岩裂隙水及碳酸岩裂隙岩溶水三大类。通过分析不同水文构造单元地质特征，采取不同的物探方法，测量岩石的电阻率差异分析推断其富水性，研究确定富水层位并通过钻探工程验证实现地质找水。在2010—2011年山东泰安地区抗旱打井工程中，利用高密度电阻率法在解决地质找水方面取得了重要成果。

Abstract:

Main types of groundwater in Tai'an area of Shandong province are loose pore water type, metamorphic and igneous rock fissure water type and carbonate fracture-karst water type. Through analyzing hydrogeological characteristics of different tectonic units, by using different geophysical methods, resistivity differences of rocks have been measured, the watery has been donducted, rich water strata can be determined, and water exploration can be realized through geological drilling. During the period of drought drilling projects in Tai'an area in Shandong province in 2010—2011, by using high-density resistivity method, important achievements have been gained in water exploration.
