摘要
临沂市境内的沂沭断裂带为地热资源的形成提供了有利的地质条件。本文在充分收集区域地质、水文地质、地热等资料基础上,从热源、热储、盖层、通道等方面对该区地热地质条件进行总结,分析了沂沭断裂带地热资源的形成背景、赋存条件、分布规律及特征,认为北北东向沂沭断裂带为该区导热、储热构造,结合区内地层岩性分布及埋藏条件,分"新生代古近系热储、中生代白垩系热储、古生代寒武系及奥陶系热储类型。研究结果为临沂市境内进一步研究、勘探及开发地热资源提供科学依据。
The Yishu fault zone in Linyi City provides favorable geological conditions for the formation of geothermal resources.On the basis of fully collecting regional geology,hydrogeology,geothermal and other data,this paper summarizes the geothermal geological conditions of the area from the aspects of heat source,thermal storage,cover layer and channel,analyzes the formation background,storage conditions,distribution rules and characteristics of geothermal resources in the Yishu fault zone,and considers that the thermal conductivity and thermal storage structure of the north-north-east Yishu fault zone,combined with the lithological distribution and burial conditions of the stratigraphic strata in the area,are divided into“Cenozoic Paleogene thermal storage,Mesozoic Cretaceous thermal storage,Paleozoic Cambrian and Ordovician thermal storage types”.Provide a scientific basis for further research,exploration and development of geothermal resources in Linyi City.
