Abstract：According to the existing petroleum exploration and geothermal development data, the geothermal geological background and thermal storage development characteristics of Zhongmu sag has been comprehensively discussed. In this area, the sandstone sedimentary thickness of Guantao group can reach hundreds of meters. It has a good water and heat storage characteristic, and has large porosity and good permeability. The sandstone heat reservoir of the whole group has development value. According to its formation development characteristics, the segment mining of 3 ~ 4 geothermal wells can be generally implemented. The hot water temperature of the well can reach is 60 ~ 95℃, and single well water inflow 60 ~ 100 m3/ h. The deep geothermal development potential of this area is tremendous. We can alleviate the pressure of the energy effectively, and protect the natural environment by using the clean energy for urban central heating.
