摘　　要：中国江苏省和新加坡均面临着能源紧张的问题,受地理位置限制迫切需要向深层地热资源转型,而深层干热岩开发利用是其中的重要方向之一。通过对中国江苏省苏北盆地和新加坡构造和沉积等基础地热地质进行对比分析,认为二者均位于环太平洋地热异常带周缘,且断裂体系和火成岩广泛发育,指示了优异的深部地热背景。通过对地温场的分析,揭示出二者的大地热流和地温梯度均高于大陆平均水平,其中新加坡更是具有世界级的高温背景。近年来,在苏北盆地成功探获的寒武系—奥陶系干热岩,为新加坡深部地热资源开发提供了重要的启示。干热岩的形成与板块俯冲作用密切相关,热流通过断裂向上传递,同时加热地表水和/或地下水,并最终在断裂交汇处出露温泉。研究成果不仅阐明了苏北盆地和新加坡的基础地热地质和地温场特征,还为实现区域能源自给自足提供理论支撑。Both Jiangsu Province in China and Singapore are facing energy shortages,and due to geographical limitations,there is an urgent need to transform towards deep geothermal resources.The development and utilization of deep hot dry rock is one of the important directions.By comparing and analyzing the basic geothermal geology of the Subei Basin in Jiangsu Province,China and Singapore,it is believed that both are located around the Pacific geothermal anomaly zone,and the fault system and igneous rocks are widely developed,indicating an excellent deep geothermal background.Through the analysis of the geothermal field,it is revealed that the terrestrial heat flow and geothermal gradient of both are higher than the average level of the mainland,with Singapore having a world-class high-temperature background.In recent years,the successful exploration of Cambrian-Ordovician hot dry rock in the Subei Basin has provided important insights for the development of deep geothermal resources in Singapore.The formation of hot dry rock is closely related to plate subduction,where heat flow is transmitted upwards through faults,heating surface water and/or groundwater,and ultimately exposing hot springs at the intersection of faults.This reserrch not only elucidates the basic geothermal geology and geothermal field characteristics of the Subei Basin and Singapore,but also provides theoretical support for achieving regional energy self-sufficiency.
