EH4电磁成像系统在莱州湾地区探测海水入侵界限的调查研究
Survey and Study on Exploring the Interface of Saltwater Intrusion by Using the EH4 Electromagnetic Imaging System in Laizhou Bay Area
摘要
Abstract
Through the analysis of the application cases by using the EH4 electromagnetic imaging system to ex-plore seawater intrusion in Laizhou bay area, we found that apparent resistivity inversion section of the EH4 elec-tromagnetic imaging system contains a large amount of geological information,inversion section reflects not only the strata thickness variation of the vertical and horizontal extension on saltwater and freshwater, and establishes the relationships of every strata, but also the burial depth of stratum and the strata of ups and downs.We use the cross section of apparent resistivity to identify boundary of salt water and freshwater. The result of saltwater and freshwater interface with the inversion section of the EH4 electromagnetic imaging system is almost consistent with the result of hydrogeological survey, and this method is effective and feasible in Laizhou bay area. The appli-cation of the EH4 electromagnetic imaging system in the exploration of seawater intrusion has the advantages of simple, fast and so on, it has very good prospects and worth spreading and popularizing.关键词
