山东费县上冶地区地热资源特征研究
|
摘要
山东省临沂市被授牌为"中国地热城"。区内地热资源较为丰富,开发利用时间长,产生了显著的经济和社会效益。通过研究临沂市费县上冶地区的地质背景、地热地质特征,探求该地区的地热资源形成、发育的机理,对于指导区域地热资源的有效开发具有重要的意义。上冶地区南部奥陶纪马家沟群地层直接出露,大气降水直接或者间接补给岩溶热储含水层。近SN向的上冶东岭断裂及其次级断裂与蒙山断裂沟通,地下水通过断裂构造、岩溶孔洞、裂隙等通道向深部径流,受到大地热流的传导加热,在形成和运移过程中不断地溶滤热储围岩的各种化学成分。而上覆地层热导率低,具有一定的保温作用,从而使得地热资源在该地赋存和聚集。深部岩溶热储类型为典型的受断裂构造控制的层状兼带状热储。
Linyi city in Shandong province is licensed as " geothermal city in China". Geothermal resources in the area are abundant and the history of development and utilization is long,which produce significant economic and social benefits. By studying geological background and geological characteristics of geothermal resource in Feixian county in Linyi city,the formation and development mechanism of geothermal resources have been discussed. It has great significance in guiding effective development of geothermal resources in this region. In the south Shangye area,the strata of ordovician Majiagou group is directly exposed,and the atmospheric precipitation is directly or indirectly replenished the karst thermal storage aquifers. Shangyedongling fault with the trend of SN and its secondary fault communicate with Mengshan fault. Groundwater runs off through fracture structure,karst holes,cracks and other channels to the deep,and heated by the conduction of the terrestrial heat flow. Various chemical constituents of the surrounding rock dissolved in the process of formation and migration. The thermal conductivity of overlying strata is very low. Thus,it has a certain thermal insulation effect,and geothermal resources can be deposited and accumulated in the area. The deep karst geothermal reservoir type in this area is typically the layered and zonal geothermal reservoir controlled by fracture structure.
