江西省东部地区干热岩资源前景分析

摘要

The abundant and widely distributed HDR is a kind of new renewable energy source with predominance of environmental protection, reliable and sustainable etc. Through comprehensive analysis of strata outcropping, regional structural features, magmatic rock distribution and geothermal geological features in eastern part of Jiangxi Province, have found that the terrestrial heat flow value in the area is rather high, granitoid rock body developed, many presents as large batholith, thus the high heat production hidden rock body with higher thermoconductivity and well preserved radiogenic heat. Only the 11 HDR favorable areas preliminary selected, has HDR re-sources 16.5 billion tons coal equivalent estimated through volumetric method. It follows that prospect of HDR resources in eastern part of Jiangxi Province is excellent, abundant HDR resources are of great significance to the“short of coal and gas without oil”Jiangxi Province, thus to carry out HDR resource investigation and evaluation in the area as soon as possible has been advised.%干热岩分布普遍，储量丰富，作为一种可再生的新型能源，具有环保、可靠、可持续等优势。通过对江西省东部地区的出露地层情况、区域构造特征、岩浆岩分布及地热地质特征等综合分析研究，发现区内大地热流值较高，花岗岩类岩体发育，多呈大型岩基产出，存在热传导率高、放射性热保存较好的高产热率隐伏岩体。仅对初步优选的11个干热岩有利区，用体积法估算干热岩资源量就高达165亿t标准煤。由此可见，江西省东部地区干热岩资源前景良好，丰富的干热岩资源对“缺煤少气无油”的江西省意义重大，建议尽早对江西省东部地区开展干热岩资源的调查评价工作。
