Abstract With the further advancement of the energy reform,the exploration,development and utilization of geothermal energy in the middle and deep clean energy are imminent.At present,the exploration,development and utilization focus on the middle and deep level, mainly in urban areas,which limits the use of conventional seismic,magnetotelluric and other geophysical prospecting methods, and new methods need to be introduced. In this article,through micro exploration technology in some urban areas to carry out the relevant experiments, comparison of previous high precision gravity,magnetotelluric sounding,geothermal hole data,verified the micro test result,interpretation of stratigraphic classification and tectonic position was consistent with known data,deserves further research and promotion,to realize micro exploration technology in deep geothermal energy in the fast exploration and development is of great significance.
