综合物探方法在内蒙古敖汉旗林家地地热资源勘查中的应用试验
Application of comprehensive geophysical prospecting in the exploration of geothermal resources in the Linjiadi area,Aohan Banner,Inner Mongolia
摘要
Abstract
In the context of the goals of both peak carbon dioxide emissions and carbon neutrality,scientific and efficient exploration and exploitation of geothermal resources are criticalfor the geothermal industry.To address the commonly concernedtechnical challenges in the exploration of moderately deep geothermal resources,this study investigated the effectiveness of comprehensive geophysical pros-pecting in the exploration of geothermal resources inthe Linjiadi area,Aohan Banner,Inner Mongolia.Based on the analysis ofthe geo-logical and hydrogeological conditions,this studypreliminarilyascertainedthe geothermal field characteristicsand the hydrochemicalchar-acteristics of groundwater in the Linjiadi area.By comprehensively employingcontrolled source audio-frequency magnetotellurics(CSAMT),CSAMT;microtremor survey;radioactive radon survey;this study roughly determined the distribution of strata,magmatic rocks,and fault structures in the study area,inferring the factors controllinggeothermal anomaly areas and hot-water migration.Accord-ingly,exploration boreholes were arranged,allowing for drilling verificationwith a total length of 960 m.The results show that the com-prehensiveapplication of CSAMT and microtremor survey,combined with radioactive radon survey for auxiliary verification,is effective in exploringmoderately deep geothermal resources.This study will provide a methodological reference for geothermal resource explora-tion in other areas.关键词
