摘要
河南通许凸起尉氏县西部地热田总面积约170 km^2,地热地质背景优势明显,地热资源开发利用潜力巨大。地热资源类型为传导型层状热储,地温梯度2. 46~3. 26℃/100 m,1300 m埋深水温为42~53℃。主要热储层为新近系明化镇组和馆陶组,热储结构单一。根据地质资料综合整理分析进行地热资源评价,建立热储模型,估算地热田1300 m已浅的热储储存热水资源总量为315. 33×108m^3,地热流体可开采热水资源总量为98. 71×104m^3/a,折合标准煤3573. 59t/a,为该区下一步勘查、开发利用和远景规划提供了依据。
The geothermal field discussed in this paper is located in the west of Weishi County,Tongxu Uplift,with a total area of about 170 km^2.It has obvious advantages in geothermal geological background and huge development and utilization potential of geothermal resources.The geothermal resources are conductive layered reservoirs,with a geothermal gradient of 2.46-3.26℃/100 m and a buried water temperature of 1300 m of 42-53℃.The main thermal reservoirs are the Neogene Minghuazhen Formation and Guantao Group.The geothermal resources were evaluated based on the comprehensive consolidation and analysis of geological data,and the thermal storage model was established.The total amount of shallow thermal storage and hot water resources in the 1300 m geothermal field was estimated to be 315.33×108 m^3,and the total amount of geothermal fluid exploitable hot water resources was 98.71×104 m^3/a,which was equivalent to 3573.59 t/a standard coal,providing a basis for further exploration,development and utilization,and longterm planning in this area.
