济南东部宁家埠地区地热资源特征与开发利用探讨
|
摘要
济南市东部宁家埠地区蕴藏着丰富的地热资源,地质构造条件、热储地质条件都比较有利,是开发地热资源的有利地区。通过对章宁1地热井钻探资料的分析,结合近年来的勘查项目研究成果,笔者认为宁家埠地热田属于岩溶裂隙层状传导型地热田,在区域地质构造上主要受文祖断裂控制,热储层主要为奥陶纪马家沟群灰岩。该区的地温梯度主要受构造控制,断裂导热是形成本区地热田的一个重要因素。地下热水矿化度较大,富含多种对人体有益的矿物、元素,开发利用前景广阔。
The Ningjiabu area to the east of Jinan has abundant geothermal resources with beneficial structural and reservoiring conditions,thus a favorable area to exploit geothermal resource. Through analysis of drilling data from the Zhangning No. 1 geothermal well,combined with exploration project studied results in recent years,the author has considered that the geothermal field in the area belongs to karst fracture layered conduction type,regional tectonically is mainly controlled by the Wenzu fault; the heat reservoir is mainly Ordovician Majiagou Group limestone. Geothermal gradient in the area is mainly structural controlled; fault heat conduction is the major factor to form the geothermal field. Geothermal water mineralization is large,rich in a variety of beneficial minerals and elements to human body thus have a wide prospect to exploitation and utilization.
