摘要
本文在研究和政县勘查区已有基础地质、水文地质以及物探资料的基础上,分析有利于地热形成的区段,基于可控源音频大地电磁法(CSAMT),结合地质、地球物理特征,对数据资料进行了处理与反演解释。进而对研究区2000 m以内的浅盆地盖、储层位进行了分层,分析和探讨了勘查区及其外围的地层岩性、地质构造活动,明确了地热井勘探靶区,为进一步勘探和开发和政县地热资源提供科学依据。
On the basis of fully collecting and making use of the existing basic geological,hydrogeological and geophysical data in the exploration area of Hezheng County,this paper analyzes the regions conducive to the formation of geothermal energy.Based on the controllable source audio-frequency magnetotelluric method(CSAMT),combined with geological and geophysical characteristics,the data are processed and interpreted inversion.Furthermore,the cover and reservoir positions of shallow basins within 2000 m in the study area are stratified,and the stratigraphic lithology and geological tectonic activities of the exploration area and its periphery are analyzed and discussed.The geothermal well exploration target area is defined,which provides scientific basis for further exploration and development of geothermal resources in Hezheng County.
