摘要
新乡市平原示范区独特的自然地理条件和地质环境条件,赋存了丰富的地热资源。研究了新乡市平原示范区地热资源地质特征,研究区属于中牟凹陷地热区,主要热储层为新近系明化镇组半固结碎屑岩孔隙裂隙热储层、新近系馆陶组半固结碎屑岩孔隙裂隙热储层、古近系半固结碎屑岩孔隙裂隙热储层,地热类型为层状分布的盆地型地热,地温场类型为地层热传导型,区内断裂无显著导热、导水特征,地温场以地层传导型为主,地温梯度在2.33~3.02℃/hm。并分析了开发利用情况,根据研究区开发利用潜力,为平原示范区建设绿色低碳城市提供地下清洁能源开发利用技术。
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.
