济北地热田地质特征

Geological Characteristics of Geothermal Field in North of Jinan City

摘要:

济南地热田热储层为古生界奥陶系石灰岩,盖层为新生界第四系、新近系、古近系、二叠系和石炭系;热源为沿区内深大断裂上涌的大地热流。经地热钻孔揭露,地下热水水温57℃左右,水化学类型为SO4Ca型,矿化度3~6g/L,是具有医疗价值的热矿水。单井可采资源量为2585.52m3/d,折合标准煤16.1t/d,在100年内所放的总热量1.72×1016J。依法科学合理的开发济河地热资源必将为济南市区北跨、招商引资、发展绿色高效农业等都有着十分重要的意义。

Abstract:

Geothermal reservoir layers in Jinan city is Palaeozoic Ordovician limestone, while covering stata are Quaternary, Neogene, Paleogene, permian and carboniferous in Cenezoic system. Thermal resource is geothermal flow eruppted from deep part. As uncovered by geothermal drilling, temperature of geothermal water is 57℃, hydrochemical type is SO_4Ca, and mineralization degree is 3~6g/L. It is geothermal mineral water with medical value. Mining amount of single well is 2585m3/d, which is equal to 16.1t/d of stan...
