| 摘 要： | 干热岩是一种清洁的可再生地热资源，随着开发技术日趋成熟，显示出其巨大的利用价值。江苏地区中、新生代发 育大量火山活动，深部热源上涌，具有良好的干热岩赋存背景。文中在对江苏地区大地热流值、不同深度岩石热导率、生 热率分析的基础上，利用贡献率叠加法，对苏北盆地与苏南地区不同深度的温度进行估算，将5~8 km的温度计算结果与采 用温度梯度计算方法所得数据进行对比分析，在此基础上对江苏地区3 km至8 km深处干热岩资源量进行预测。结果显示， 江苏地区3~8 km深处干热岩资源总计为2.18×1021 J，合74.9亿吨标准煤，按2%的可开采资源量计算，即合1.5×108 t标准 煤，约相当于江苏省一年能源消耗总量的一半，开发利用前景巨大。 |

| Abstract: | As a clean renewable geothermal resource, the hot-dry-rock has been more and more maturely utilized because of its obviously increasing values. The extensive volcanic activities and upwelling flow of deep-seated thermal energy in Jiangsu Province during the Mesozoic and Cenozoic time provided abundant hot-dry-rock storage. Based on an analysis of the heat flow, rock thermal conductivity at different depths, radioactive heat generation, and the temperatures at different depths in Jiangsu Province are calculated using the contribution rate of the superposition method. The calculated results are compared to the data from thermal gradient method in 5~8 km, eventually the hot-dry-rock resource amount at the depth of 3~8 km in Jiangsu Province is estimated by means of the volume method. The results show that the resource amount at the depth of 3~8 km could reach 2.18×1021 J, which is equivalent to the heat of 7.49 billion tons of standard coal. On the basis of 2% of the exploitable rate, the resource is estimated to be half of the current total energy consumption of Jiangsu Province in a year (about 0.15 billion tons of standard coal), thus demonstrating a promising potential for utilization. |
