Abstract

This paper presents a comprehensive review of the applications and advances of numerical simulation in hydrothermal geothermal systems. It begins by outlining the global resource potential and basic characteristics of these systems while also identifying the limitations of conventional static resource assessment methods. Subsequently, it elaborates on how numerical simulation, based on thermal–hydraulic–mechanical–chemical (THMC) coupling theory, serves as an essential dynamic prediction tool for resource potential assessment, development optimization, long-term evolution forecasting, and environmental risk management. Furthermore, this review introduces commonly used simulation software and multi-field coupling frameworks and analyzes their specific applications through representative cases, including sedimentary basins, uplifted mountain systems, and high-temperature geothermal systems. Finally, current technical challenges are summarized, and future perspectives are discussed, highlighting the integration of big data and artificial intelligence and the development of digital twin technologies.
