摘要
EH4电阻率成像系统是将部分可控源与天然源相结合的一种大地电磁测深系统。电测井是通过测量人工或天然电场,研究钻孔剖面地层电学性质的一种方法。本文以坦桑尼亚某电厂水文地质勘察为例,说明这两种方法在查明该场区的地层结构、基岩面起伏以及覆盖层中的水文地质情况具有良好的应用效果。实践证明,大地电磁测深、钻孔电阻率测井及自然电位测井是水文地质勘察中最优的物探手段。
EH4 electromagnetic image systemis a kind of magnetotelluric sounding system controlled source with the combination of natural sources. Electric logging is measured by artificial or natural electric field. It is a kind of method to research the electrical properties of borehole sections. In Tanzania, hydrogeological exploration of a certain power plant as an example, shows that the two methods in identification of the stratigraphic structure and the bedrock surface fluctuation and the hydrological geology layer has a good application effect. Practice has proved that EH4 electromagnetic image system, drilling resistivity logging and spontaneous potential logging are the optimal means of geophysical prospecting in the hydrogeologieal exploration.
