Study on geologic characteristics and development and utilization of geothermal resources in Xinxiang Plain Demonstration Area

Xinxiang Plain Demonstration Area is rich in geothermal resources due to its unique natural geographical and geological environmental conditions.This paper studies the geological characteristics of geothermal resources in the Xinxiang Plain Demonstration Area.The study area belongs to the Zhongmou depression geothermal area.The main thermal reservoirs are the semi-consolidated clastic rock pore-fissure thermal reservoir of the Neogene Minghuazhen Formation，the semi-consolidated clastic rock pore-fissure thermal reservoir of the Neogene Guantao Formation，and the semi-consolidated clastic rock pore-fissure thermal reservoir of the Paleogene. The geothermal type is the basin-type geothermal distributed in layers. The geothermal field type is the formation heat conduction type. The fractures in the area have no significant heat and water conduction characteristics. The geothermal field is mainly the formation conduction type，and the geothermal gradient is 2.33~3.02 ℃/hm.Based on the analysis of the development and utilization situation，according to the development and utilization potential of the study area，the proposal for the development and utilization of hydrothermal geothermal is proposed，which provides a technical basis for the development and utilization of underground clean energy for the construction of green low-carbon cities in the plain demonstration area.
