摘要
会昌坝背地区地热水资源较为丰富,但因并未得到充分利用。为解决此问题,以便更有效地开发利用地热水资源,在分析地质条件、水文地质条件的基础上,根据对以往资料整理分析,利用物探电性对比成果,结合钻探、抽水试验等方法对其进行分析研究。结果认为:热储覆盖主要为白垩系晚期茅店组,热源层为印支期晚三叠世罗珊序列(γtT_3)黑云、二云母花岗岩,地热水主要分布在F_7和F_6断层之间,并呈南北方向带状展布,主要受深部F_7、F_6、F_2断裂控制。
The Babei area in the Huichang County has abundant geothermal resources,but not yet be fully utilized. To resolve the issue,so that to more effectively exploit and utilize geothermal water resources,on the basis of geological,hydrogeological conditions analysis,combined with previous data sorting and analysis,using geophysical prospecting electrical properties contrast,as well as drilling,pumping test carried out analytical study. The result has considered that geothermal reservoir overburden is mainly late Cretaceous Maodian Formation; geothermal source is Indo-Chinese Epoch late Triassic Luoshan succession( γtT3) granitite,two-mica granite.Geothermal water is mainly distributed between faults F7 and F6,presented NS zonal distribution,mainly controlled by deep part faults F7,F6 and F2.
