济南市孔隙裂隙地热田热储特征及开发利用模式探讨

Discussion on Characteristics and Exploitation and Utilization Model of Pore-crack Geothermal Fields in Jinan City

以济南市孔隙裂隙地热田地质条件为背景,在全面掌握济南市地热勘查情况的基础上,论述了济南市孔隙裂隙热储特征,认为馆陶组热储埋深适中,富水性较强,属于中低温热储,是济南市孔隙裂隙热储层区最为适宜的开采层;而东营组热储层埋藏较深且分布不稳定,部分地区缺失,富水性较差,目前单独成井开采适宜性较差。并根据热储特征及区位优势,对地热资源开发利用模式进行了探讨。

Based on geological conditions of pore crack geothermal field in Ji'nan city,on the basis of grasping basic situation of geothermal exploration in Jinan city,characteristics of pore crack geothermal fields in Jinan city have been introduced.It is regarded that buried depth of Guantao geothermal reservoir is moderate and water abundance is strong.It belongs to the medium low temperature geothermal reser-voir.It is the most suitable mining layer in fracture pore reservoir area in Ji'nan city.Dongying geothermal reservoir is deeply buried,the distribution is not stable,and some areas are lack water.The suitability of single well is poor.According to characteristics and regional advantages of geothermal fields,exploitation and utilization of geothermal resources have been studied.
