摘要: 为了对南昌盆地后续地热资源勘查选区及开发利用提供理论指导，采用岩石热物性参数测试、钻孔测温等方法，对研究区大地热流值进行计算，分析了大地热流特征和影响因素. 结果表明南昌盆地地温梯度分布在14.3~45.5 ℃/km之间，平均为31.9 ℃/km；岩石热导率分布在2.132~4.300 W/（m·K）范围内，平均为2.863 W/（m·K）；计算得出南昌盆地现今大地热流值在62.26~96.95 mW/m2之间，平均值为76.22 mW/m2. 热流分布具有显著“东高西低”特征. 基于对大地热流特征的研究，结合区内热储赋存条件，认为昌北-莲塘和璜溪-厚田两个区域有较好的地热资源勘查前景.Abstract: In order to provide theoretical guidance for the selection and development of geothermal resources in the Nanchang Basin, methods such as rock thermal property parameter testing and borehole temperature measurement were used to calculate the heat flow values in the study area, and the characteristics and influencing factors of geothermal flow were analyzed. The results show that The distribution of geothermal gradient in Nanchang Basin is 1.43-4.55 ℃/hm, with an average of 3.19 ℃/hm; The thermal conductivity of the rock is 2.132-4.300 W/(m·K), with an average thermal conductivity of 2.863 W/(m·K); The current heat flow value in the Nanchang Basin is calculated to be 62.26-96.95 mW/m2.The distribution of heat flow has a significant characteristic of "high in the east and low in the west".Based on the study of the characteristics of geothermal flow in the earth and the occurrence conditions of thermal reservoirs in the area, it is believed that the exploration prospects of geothermal resources in the Changbei-Liantang and Huangxi-Houtian regions are promising.
