摘要
通过对沂沭断裂带临沂段地热地质条件研究,认为本区地热形成与断裂、构造、岩浆活动相关;通过测温、遥感解译等手段,确定汤头、穆柯寨、芝麻墩地热异常区及地温梯度的空间变化。结合钻探资料,确定汤头地热异常区热储为白垩系青山群的安山岩,穆柯寨、芝麻墩地热异常区热储为白垩系王氏群的砂砾岩。在建立热储概念模型的基础上,计算了3个异常区的地热储量分别为3.63×1017J、1.50×1017J、0.72×1017J,为该区域的地热资源开发利用与保护提供了依据。
Though the research geothermal geological condition, this article found out that the geothermal formation in Linyi segment of Yishu fault zone was relation with the fault, geological structure and magmatic activities. Though the method of temperature measurement and remote sensing interpretation, it ascertained Tangtou, Mukezai and Zhimadun for geothermal abnormal areas and the geothermal gradient changed in space. Combining with drilling data, the geothermal reserves of Tangtou geothermal abnormal field was cretaceous Qingshan formation and the Mukezhai, Zhimadun geothermal abnormal fields were glutenite of wangshi formation. On the foundation of geothermal reservoir idealized model, it calculated the storage of the three anomaly zones. Respectively, they were 3.63×10^17J、1.50×10^17 J、0.72×10^17 J, this provided the basis for the development and utilization and protection of the geothermal resources in this area.
