蔚县盆地地热成因机制与地质构造作用相关性分析
Correlation analysis between geothermic genetic mechanism and geological tectonics in Yuxian Basin
摘要
Abstract
In order to study the basin-type geothermal resources genesis,the authors took Yuxian Basin as the study object to conduct the distribution and conditions of geothermal resources in Yuxian Basin through data col-lection,geothermal geological survey,routine water sample collection and analysis,MT survey,deep geothermal fluid depressurization experiment,geothermal fluid sample collection and comprehensive analysis.And 5 geother-mal anomaly areas were delineated.From the perspective of geological structure,three geothermal geological zones have been further divided in the demarcated abnormal area mentioned above,including the geothermal area with monoclinal structure in the northern Huliuhe Fault,the geothermal area in the fault depression basin in the south-ern Huliuhe Fault,and bedrock uplift area in the eastern Songzhikou-Yousuobu Fault.Based on geological tec-tonic action such as faulting,sedimentation,fault structures and magmatic activities,the correlation between the geological tectonic action and the mechanism of geothermal genesis was studied by the method of analysis and in-duction.The research show that the geological tectonic processes in Yuxian Basin provided basic conditions for the formation of geothermal resources.The faulting and sedimentary processes enabled Yuxian Basin to form excellent carbonate rock thermal reservoirs and cover layers,making a favorable thermal storage conditions.Fracture is not only a channel for conducting deep thermal energy,but also a way for shallow water to infiltrate.Deep magmatic activities have given rise to structural frameworks and continuously provided deep thermal energy.This basin has the characteristics of a mineral basin,a water basin and a thermal basin.This research results could provide refer-ences for future exploration of basin-type geothermal reservoir.关键词
