EH-4大地电磁测量仪在山东泰安徂徕地热田勘察中的应用

Application of EH-4 Electromagnetic Measuring Apparatus in Exploration of Culai Geothermal Field in Tai'an of Shandong Province

摘要:

大地电磁测量仪是近几年引进的美国Stratagem大地电磁测量系统。该系统设计了特殊的人工电磁波发射源，提高了700m深度范围的勘探效果，同时又避免了地形地物对物探勘察的工作布置限制。大地电磁测深反演电阻率断面较清晰地反映了地热田导水导热断裂构造的地热地质特征，是基岩构造裂隙带状热储类型的有效勘探方法。

Abstract:

EH-4 electromagnetic measuring apparatus is an electromagnetic system imported from America. In this system, special artificial electromagnetic cave emissio source is designed in this system, which promoted exploration effect in the depth scope of 700m, and avoided arrangement limitation of surface and landscape to physical exploration. Conversion electrical resistivity profiles reflects geotheraml geological characteristics of transmissing water and heat in geothermal field. It sis effective method for exploring structural crack belt type heat reserve in basic rocks.
