摘要
沂沭断裂带是由四条主干断裂组成的深大断裂带,带内地热露头较多,蕴藏着较为丰富的地热资源。本文试图从区域地质角度对沂沭断裂带的地层结构、构造的导水控热性能以及热储特征等成热地质条件进行分析研究,提出沂沭断裂带内的正确勘查方向,以便有目的、有计划地开展地热资源勘查工作,以期促进沂沭断裂带地热资源勘查的新突破。通过分析,沂沭断裂带内西部马站-苏村地堑的成热地质条件优于东部安丘-莒县地堑,沂沭断裂带中段是进一步开展地热资源勘查的有利地段,而NW、NEE向次级断裂与主干断裂的交汇处是地热资源勘查的主要靶区,推断-葛沟断裂两侧存在深部灰岩热储。
The Yishu River fault zone is composed of 4 faults where it is rich in geotherm and geothermal outcrops appear frequently. This article attempts to investigate the geological condition of the geotherrn forming, strata structure of the zone, fault structural water- and heat-conductivy in order to develop geothermal resource surveying work. It is suggested that, in the Yishu River fault zone, the geotherm-forming condition in the western part of the fault zone, Mazhan-Sucun graben, is better than that in the eastern part, Anqiu-Yingxian area. And the best part to prospect the geotherm next is in the middle part of the zone. And the interscection of the NW and NEE direction sub-fauhs and the main faults are the impotant target of geothermal resource investigation. And there may be a geothermal storage in the deep-seated Karst rock in both sides of Tangwu-Gegou fault.
