【摘要】 根据湖南省区域地质背景,高热流区均处于板块构造带或构造活动带,在湖南幕阜山、沩山、诸广山等地区分布有范围较大的火山岩体,说明湖南省具备干热岩地热资源形成的区域构造条件。通过对省内出露地层、岩浆岩、构造、地温梯度和大地热流综合分析,发现湖南省花岗岩类岩体发育,存在大地热流值较高、生热率及放射性热保存较好的干热岩隐伏岩体。在此基础上,利用地球物理方法圈定了7个干热岩有利区。并通过体积法估算2～6 km深度有利区干热岩资源量约达1.18万亿t标准煤。更多还原

【Abstract】 According to the geological background of Hunan province, the high heat flows are all in the plate tectonics or active tectonic zone. There are a wide range of volcanic rocks in the mountainous areas of the Mufu-mountain, Weishan and Zhuguang mountains of Hunan, indicating that the Hunan province have the regional tectonic conditions for the geothermal resources of hot dry rocks(HDR). By comprehensive analyzing of the strata, magmatic rocks, tectonic, geothermal gradient and heat flow, it is found that the development of granite rock mass in our province has high heat flow value, high heat rate and high heat preservation of HDR. On this basis, have used geophysical methods to trap seven favorable areas of HDR. By means of volume method, the amount of the hot dry rock in the favorable area of 2 to 6 km is estimated to be about 1.18 trillion tons of standard coal.更多还原
