济南北部地热田地热地质特征浅析

Analysis on Geological Characteristics of Geothermal Field in North Part of Jinan City

摘要:

济南北部地热田地热资源类型属于层状裂隙岩溶型，热源是北部齐河广饶断裂的沟通导热，盖层是第四系、新近系、石炭[CD*2]二叠系、侏罗系。可利用的、具有开发价值的热储层为奥陶系灰岩热储，该热储层顶板埋深在700~2500m左右，热储层厚度由南向北逐渐增大，单井涌水量2000m3/d左右，孔口水温一般在38~57℃，地热田东部地热水矿化度1.4~3.5g/L左右，西部5.1~7.2g/L左右，地热水中富含氟、锶、偏硅酸等微量元素，具腐蚀性，结垢性弱，具较好的开发利用价值。经计算奥陶

Abstract:

Geothermal field in north of Jinan city belongs to layered fractured karst type, and heat conduction in north of Qihe- Guangrao fault is its heat source.Quaternary, early Tertiary, Carboniferous-Permian and the Jurassic period are its covering layers. Or
