【摘要】：選擇理想靶區(qū)建立中國第一個EGS示范工程,在中國節(jié)能減排及應(yīng)對全球氣候變化過程中具有重大的戰(zhàn)略意義。根據(jù)全國大地?zé)崃鲌D、居里面深度圖、新構(gòu)造運動圖、酸性巖體分布圖,通過剖面分析,將中國EGS靶區(qū)分為板塊構(gòu)造活動、近代火山、沉積盆地和酸性巖體分布4種類型,分析了各類型干熱巖靶區(qū)的產(chǎn)熱特征。遴選了10個靶區(qū)通過建立指標體系進行EGS示范工程選址指標分析,指標包括大地?zé)崃�、熱儲巖性、覆蓋層厚度、居里面深度、地應(yīng)力(構(gòu)造歷史)、放射性生熱率、地溫梯度、區(qū)域經(jīng)濟8個指標,在對指標分析打分的基礎(chǔ)上最終確定羊八井、陽江、漳州、福州等為中國EGS潛在靶區(qū)。通過典型地區(qū)的熱結(jié)構(gòu)剖面分析說明了評價結(jié)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.
