【摘要】：选择理想靶区建立中国第一个EGS示范工程,在中国节能减排及应对全球气候变化过程中具有重大的战略意义。根据全国大地热流图、居里面深度图、新构造运动图、酸性岩体分布图,通过剖面分析,将中国EGS靶区分为板块构造活动、近代火山、沉积盆地和酸性岩体分布4种类型,分析了各类型干热岩靶区的产热特征。遴选了10个靶区通过建立指标体系进行EGS示范工程选址指标分析,指标包括大地热流、热储岩性、覆盖层厚度、居里面深度、地应力(构造历史)、放射性生热率、地温梯度、区域经济8个指标,在对指标分析打分的基础上最终确定羊八井、阳江、漳州、福州等为中国EGS潜在靶区。通过典型地区的热结构剖面分析说明了评价结果的合理性。
[Abstract]:Choosing the ideal target to establish the first EGS demonstration project in China is of great strategic significance in the process of energy saving and emission reduction in China and in the process of dealing with global climate change. The neotectonic movement map and acid rock mass distribution map are divided into four types: plate tectonic activity, modern volcanism, sedimentary basin and acid rock mass distribution. The heat production characteristics of various types of dry hot rock targets are analyzed. Ten target areas are selected to analyze the site selection index of EGS demonstration project by establishing index system, including earth heat flow, thermal reservoir lithology and overburden thickness. The depth, stress (tectonic history, radioactive heat generation rate, geothermal gradient, regional economy) of the inner residential area are 8 indexes. Based on the analysis and grading of the indicators, Yangbajing, Yangjiang and Zhangzhou are finally determined. Fuzhou is the potential target of EGS in China. The rationality of the evaluation results is proved by the analysis of the thermal structure profile of typical areas.
