This paper summarizes the research progress of geothermal energy heat transfer basic theory and heat transfer enhancement technology, and focuses on the application and optimization of nanofluid and porous medium in geothermal energy utilization. Firstly, the basic concept, classification and theoretical basis of heat transfer mechanism are introduced, and the heat transfer problems in geothermal energy utilization are analyzed. Subsequently, the application of nanofluid in geothermal energy is described in detail, including its preparation method, heat transfer performance test, challenges in practical application and economic analysis. At the same time, the heat transfer enhancement technology of porous media is deeply discussed, from the types and selection of porous media, heat transfer model establishment, experimental verification and data analysis, to the optimization of porous media technology direction, all are systematically discussed. On this basis, the overall design idea of the geothermal energy utilization system is further put forward, including the selection and configuration optimization of the key components, the optimization strategy of the system operation parameters, and the system performance evaluation and improvement measures. This study aims to provide theoretical basis and technical support for the efficient utilization of geothermal energy through the combination of theoretical analysis and experimental verification, promote the sustainable development of geothermal energy technology, and promote the optimization of global energy structure and the realization of sustainable development goals.
