摘　　要：对苏北盆地建湖隆起的干热岩资源潜力进行评价,展示华东地区沉积盆地型干热岩资源的勘探前景。基于野外勘察、室内实验和数值模拟等多手段地质分析方法分析研究区干热岩地热地质条件,以4个区域地震地质剖面为基础,建立二维热传导数值模型,模拟分析深部地温分布,确定评价深度。应用基于体积法的蒙特卡罗模拟给出合理的资源量评价分析。该方法可充分考虑参数估计的不确定性。结果表明,建湖隆起3~10 km深度内干热岩资源的可采热资源量约为44.6亿t标煤,发电潜力为692 769.9 MWe,约为江苏省2022年全年用电量的49倍。This study presents an estimation of the potential of hot dry rock(HDR)resources in Jianhu Uplift,Subei Basin,demonstrating the feasibility of exploring HDR geothermal resources within the East China sedimentary basin.An integrated geological investigation was conducted,involving field work,laboratory measurements,and numerical modeling to assess the HDR geological conditions within the study area.Four geologic sections were utilized to construct 2D heat conduction numerical models,which were instrumental in comprehending the geo-temperature field and determining the estimated depth.Subsequently,a Monte Carlo simulation,employing the volume method,was applied to provide a reasonable potential estimation.This modified method effectively accounts for uncertainties associated with estimation parameters.The results show that the amount of recoverable heat resources of HDR geothermal resources within 3-10 km depth in Jianhu Uplift is about 44.6×108 tons of standard coal and the generation potential is 692769.9 MWe,more than 49 times the annual electricity consumption of Jiangsu Province in 2022.
