摘　　要：地热能和石油均是重要的地下能源。地热数值模拟和油藏数值模拟是评估、优化地热能和石油开发利用过程中的关键技术,在能源领域具有重要指导意义。通过对比地热数值模拟和油藏数值模拟数学模型的基础架构、数值解法、案例分析,揭示了数值模拟方法在开发2种能源过程中的相似点和差异性。在模拟方法方面,地热数值模拟侧重于热传导和地温场变化特征,而油藏数值模拟则更加关注流体动力学和原油开采过程;在模拟结果方面,地热数值模拟可用于地热资源开发规划和关键生产参数优化,而油藏数值模拟则更多地应用于油田储量评估、注采参数优化和油井生产管理。通过对比分析为地热能和石油工程领域的研究和应用提供了理论参考和实践指导,有助于推动2种能源资源的高效利用和可持续发展。Geothermal energy and petroleum are both vital subsurface energy resources.Numerical simulation of geothermal and reservoir systems is a key technology for evaluating and optimizing the development and utilization of these resources,playing an essential guiding role in the energy sector.By comparing the foundational mathematical models,numerical methods,and case studies of geothermal and reservoir simulations,this study highlights the similarities and differences in their application to the development of these two energy sources.In terms of simulation methods,geothermal numerical simulations focus on heat conduction and geothermal field variation,whereas reservoir numerical simulations emphasize fluid dynamics and the oil extraction process.Regarding simulation results,geothermal simulations are used for geothermal resource development planning and the optimization of key production parameters,while reservoir simulations are primarily applied to reserve estimation,injection-production parameter optimization,and well production management.This comparative analysis provides theoretical and practical guidance for research and applications in geothermal energy and petroleum engineering,promoting the efficient and sustainable utilization of both energy resources.
