Abstract: Zhoukou depression area is rich in underground hot water resources.According to 69 geothermal drilling data and measured thermal conductivity data, the geothermal field characteristics and influencing factors of Zhoukou depression are analyzed.The geothermal gradient varies from 2.77 to 3.94 ℃/100 m, and the average geothermal gradient is 3.36 ℃/100 m.Geothermal flow density from 43.681 1 to 64.588 4 mW/m², the average geothermal heat flux is 55.724 0 mW/m².Zhoukou depression area is a medium-temperature geothermal field.The geothermal gradient and geothermal flow density are characterized by higher elevation and lower depression.The geothermal flow value is consistent with the geothermal gradient distribution law.The geothermal distribution of different horizons is opposite.That is, the temperature inside the recess is high, and the temperature on the bump and the ridge is low.Basement structure morphology, sedimentary caprock thickness, deep and large faults, groundwater and other factors determine the overall geothermal characteristics of the depression.
