| 中文摘要:从鄂尔多斯白垩系盆地地下水地球物理勘查特点出发，分析了该地区地球物理勘查所要解决的两大问题：①查明白垩系盆地地层分布特征；②进行地下水的水质判别。提出了应用频率域电磁法即Eh-4电导率成像系统解决上述两大问题的可能性，结合实例对勘查结果进行了分析，指出了Eh-4电导率成像系统勘查白垩系地层分布的合理性和进行水质判别的关键问题，认为Eh-4电导率成像系统勘查鄂尔多斯白垩系盆地地下水是合理和有效的。 |

| Abstract:Stratigraphic distribution and groundwater quality are two key problems which need to be solved in the geophysical prospecting for groundwater in Ordos Cretaceous Basin. This paper analyzes these problems and gives some exploration examples. At the same time, it is pointed out that the E h 4 electrical conductivity imaging system is useful in investigating the stratigraphic distribution and determining the water quality. |
