我国沉积盆地地热资源控热聚热机制研究OA

In the context of the global energy transition and China's"Dual Carbon"goals,geothermal resources within sedi-mentary basins constitute the bulk of the country's medium-to low-temperature geothermal reserves.Characterized by wide-spread distribution,substantial reserves,and diverse potential for utilization,their clean and efficient development is critical to ensuring energy security and sustainability.This paper systematically outlines the distribution patterns and thermal back-grounds of geothermal resources in China's sedimentary basins,summarizing the spatial characteristics of two dominant reser-voir types:porous and fracture-karst.Focusing on five key controlling elements—basement relief,groundwater activity,geo-logical structures,potential heat sources,and sedimentary caprocks—the study dissects the mechanisms governing heat redis-tribution and transfer within these systems.Through case studies of three representative regions—the Bohai Bay Basin,the Or-dos Basin,and the Southeast coastal basins—multi-factor coupled heat control models are revealed.Addressing the limitation that current research remains largely qualitative,this paper proposes that future work should prioritize quantitative simulation of multi-field coupling,refined detection of deep thermal structures,and inversion of dynamic evolutionary processes to ad-vance the scientific exploration of geothermal resources.
