摘要:

CO2地质封存—地热开发—地下储能协同技术是有机结合CO2地质封存、地热开发利用与压缩CO2储能技术的新颖尝试,是助力我国尽快完成“双碳”目标的关键技术。为此,本文凝练了CO2地质封存—地热开发—地下储能协同过程关键协同理论机制,梳理了CO2封存与羽流地热系统、增强型地热系统、含水层储热和压缩气体储能等技术协同的特点和技术现状,总结了每种技术目前面临的主要挑战,最后提出了CO2地质封存—地热开发—地下储能协同技术路径,并展望了协同技术未来的发展趋势。CO2地质封存与地热开发和地下储能相结合后,涉及两相渗流、传热、岩体变形和矿化反应之间复杂的相互作用,循环储能使各物理场时空演化规律更加复杂。现有协同技术,包括CO2羽流地热系统、CO2增强型地热系统、CO2含水层储热系统和压缩CO2储能系统,已在流动传热特性、多场耦合规律、系统性能优化等方面开展了广泛的研究工作,为CO2地质封存—地热开发—地下储能协同技术奠定了良好基础。三者协同可以实现“低碳—取热—储能”的三重目标,是未来能源系统低碳化的重要方向,有望成为“双碳”目标下的关键技术。主要的研究方向分为以下4个方面:(1)协同过程热—流—固—化多场耦合机制研究;(2)多孔储层改造与缝网长期稳定性分析;(3)封存潜力与取热性能综合评价优化;(4)封存—取热—储能全生命周期智能化调控。随着深地勘探技术的不断发展,超深储层将成为CO2地质封存—地热开发—地下储能协同技术重点关注的选址对象。目前CO2地质封存—地热开发—地下储能协同相关理论技术仍处在起步阶段,亟需解决工具设施腐蚀结垢、高温高压环境系统适应性以及与其它能源系统耦合等难题。未来应持续攻关协同系统多场耦合机制、储层改造评价和系统性能优化等关键技术,推动CO2地质封存、地热开发利用与地下储能协同技术的现场应用,并加快向深地化、智能化方向转型,积极适应全新挑战。

Abstract:

Integrated CO2 Geological Storage-Geothermal Development System-Underground Energy Storage represent a novel attempt to integrate CO2 geological storage, geothermal development and compressed CO2 energy storage technologies. This approach serves as a key technology to help China fulfill its “dual carbon” commitments within a limited timeframe. To this end, this study has systematically analyzed the key theoretical foundation of the synergistic process, reviewed the technical characteristics and development status of four synergistic pathways, including CO2 geological storage coupled with plume geothermal systems, enhanced geothermal systems, aquifer thermal energy storage and compressed air energy storage, identifying the main challenges for each. Finally, a synergistic technology pathway integrating CO2 geological storage, geothermal development, and underground energy storage is proposed, and future development trends of this integrated approach are discussed. When CO2 geological storage is integrated with geothermal development and underground energy storage, it involves complex interactions among multiphase seepage, heat transfer, rock deformation, and mineralization reactions. Cyclic energy storage further complicates the spatiotemporal evolution of these physical fields. Existing synergistic technologies, including CO2 plume geothermal systems, CO2-enhanced geothermal systems, CO2 aquifer thermal energy storage systems, and compressed CO2 energy storage systems, have been extensively studied in terms of flow and heat transfer characteristics, multi-field coupling mechanisms, and system performance optimization. These studies have laid a solid foundation for the integrated technology of CO2 geological storage-geothermal development-underground energy storage. The synergy of these three components can achieve the triple objectives of low-carbon heat extraction and energy storage, representing an important direction for the low-carbon transformation of future energy systems. It is expected to become a key technology under the dual carbon goals. The main research trends are divided into four aspects: (1) Investigation of the thermal-hydraulic-mechanical-chemical coupling mechanisms in synergistic processes. (2) Analysis of porous reservoir stimulation and long-term fracture network stability. (3) Comprehensive evaluation and optimization of storage potential and heat extraction performance. (4) Intelligent lifecycle regulation of storage, heat extraction, and energy storage. With the continuous advancement of deep-earth exploration technologies, ultra-deep reservoirs are expected to become potential target sites for the integrated technology of CO2 geological storage-geothermal development-underground energy storage. Currently, the related theoretical and technological aspects of synergistic systems are still in their infancy. Urgent issues such as equipment corrosion and scaling, system adaptability to high-temperature and high-pressure environments, and synergistic mechanisms with other energy systems need to be addressed. Moving forward, it is essential to continue tackling key technological bottlenecks, such as multi-field coupling mechanisms, reservoir modification evaluation, and system performance optimization. Efforts should be made to promote the on-site application of CO2 geological storage, geothermal development utilization and underground energy storage synergistic technologies and to drive the transformation of synergistic systems toward deeper, more intelligent, and adaptive solutions for future challenges.
