【摘要】 通过对河南许昌农科园地热资源的赋存条件进行勘查表明:许昌以东广大地区,地下500～1100m之间赋存的新近系馆陶组松散沉积层是该区主要热储层。该热储层具多层结构,粘性土与砂层互层,厚度为99～342m,顶板埋深501～738m,底板埋深619～1081m。单位涌水量为14.16m~3/d·m,渗透系数为0.25 m/d,水温62℃。合理的开发利用馆陶组在800～1200m深度或井能保证足量的可利用的热资源。更多还原

【Abstract】 Geothermal resources is one kind of cheap and clean energy sources,using the drilling methods to carry out exploration about the geothermal hosting conditions of XuChang agricultural SCI - TECH park in He Nan province.The results shows that:The main geothermal storage layers are the Neogene Guantao loose sediments which occurs within the underground from 500 - 1100m,to the east vast area of XuChang.This formation is dominated by a set of alluvial deposits.The lithology is fine sand,medium -fine sand and clay, it has a clear horizontal bedding,which the thickness is 99 -342m.Roof depth is 501 -738m,bottom depth is 619 - 1081m.According to drilling data,the specific capacity of the formation is 14.16m~3/d·m, permeablity coefficient is 0.25m/d,water temperature is 62℃.Consolidated its overlying Neogene Minghuazhen Group and its angular unconformity underlying the Archean,Proterozoic,Paleozoic geothermal storage layer to submit:Rational development and utilization plan for the use of Guantao Group 800 - 1200m depth or wells can guarantee the availability of sufficient quantities of geothermal resources,and to provide a serious water - poor urban development to the tourism industry much - needed energy demands.更多还原
