Abstract：This article mainly uses controllable source audio magnetotelluric sounding method and field Construction Method Design for the Northeastern Region of Jinan.At the same time,it also highlights the effects of different static correction methods.Finally,the integral translation method is used for multiple corrections to eliminate static effects.This laid the foundation for accurately predicting the distribution of geothermal energy.Based on the data obtained from the above processing inversion and combined with ex-isting geophysical data from the study area,this study also incorporates magnetotelluric and helium meas-urements,to establish the correspondence between the electrical layer and the stratum and electrically measured electrical anomalies and geological structures as a whole.Structural interpretation of the regional faults found in the work area,accurately determine the buried depth of the Ordovician limestone roof and the distribution of geothermal target areas.Drill verification results show,the geophysical results inferred from this geophysical exploration work are basically consistent with the actual formation conditions and the depth and location of actual geothermal resources are more consistent with geophysical anomalies.Compar-ison between electrical anomalies(corresponding faults)and anomalies in helium distribution helps to im-prove prediction accuracy of geothermal distributionand to reduce multiplicity.This program provides a new high-precision prediction method for geothermal exploration forecasting resources.
