摘　　要：随着中国“双碳”目标的推进,传统化石能源正向可再生清洁能源转型。氢能具有来源广、能量密度高和高效清洁等特点,已成为未来重要的能源构成。盐穴的气密性优势明显,且盐与氢气不发生反应,是地下大规模储氢的首选。为聚焦中国盐穴储氢技术研究和未来发展,分析了储氢地质类型及特征,详细阐述了盐穴储氢研究进展和国外运营现状;围绕盐穴储氢技术,深入剖析了大尺寸钻完井、盐穴造腔及形态控制、腔体密封性评价、井筒完整性检测及评价、管材腐蚀及氢脆控制等关键技术;总结了近年来各国制定的相关氢能政策和战略目标,结合我国盐穴储氢未来发展的机遇和挑战,对盐穴储氢地质选择和评估、大尺寸井筒完整性、盐穴造腔形态控制和密封性检测、氢能和盐业有机协同发展进行了展望,以期推进氢能规模化应用与产业链发展。研究结果为中国盐穴储氢发展和规划提供了技术参考。With the advancement of China’s carbon peaking and carbon neutrality(“dual carbon”)goals,traditional fossil energy is being transformed into renewable and clean energy.Hydrogen energy,characterized by wide sources,high energy density,and high efficiency and cleanliness,has become an important energy component in the future.Salt caverns have especially obvious advantages in terms of gas tightness,and salt does not react with hydrogen,making them the first choice for large-scale underground hydrogen storage.In order to focus on the research and future development of salt cavern hydrogen storage technologies in China,the geological types and characteristics of hydrogen storage were analyzed and the research progress of salt cavern hydrogen storage and its current situation in foreign operations were discussed.In view of the salt cavern hydrogen storage technologies,the key technologies such as large-size drilling and completion,salt cavern cavity creation and morphology control,cavity sealing evaluation,wellbore integrity testing and evaluation,and control of tubing corrosion and hydrogen embrittlement were analyzed.The relevant hydrogen energy policies and strategic goals formulated by various countries in recent years were summarized.Combining the opportunities and challenges for the future development of salt cavern hydrogen storage in China,the prospects were provided for the geological selection and evaluation of salt cavern hydrogen storage,integrity of large-size wellbore,morphology control of salt cavern cavity creation and sealing detection,and organic synergistic development of hydrogen energy and salt,with a view to advancing the large-scale application of hydrogen energy and the development of industrial chain.The results of the study can provide a reference for the development and planning of salt cavern hydrogen storage in China.
