摘　　要：利用电阻率测深法和可控源音频大地电磁测量(CSAMT)在济南西部地区进行地热资源勘查,通过地热地质调查,结合掌握的研究区内已有地热井的地层揭露情况,遵循由已知推未知的步骤,对比分析搜集的前期物探与该次物探反演结果,对物探剖面进行解译推断,查明了研究区内主要断裂构造产状及规模,比较准确地判断了热储埋藏深度,取得了较好的应用效果。By using the resistivity sounding method and the controllable source audio magneto telluric measurement(CSAMT)method,geothermal resource exploration in western Ji'nan has been carried out.Through geothermal geological surveys,according to the stratigraphic exposure of existing geothermal wells in the working area,following the steps from unknown to known,comparing and analyzing the collected geophysical prospecting results and geophysical inversion results,Interpretation inference of geophysical prospecting profile has been carried out,the occurrence and scale of the main structural fractures in the working area have been identified,and thermal storage has been judged accurately.The burial depth has achieved good application results.
