摘要深地储能是指将石油、天然气、氢气、压缩空气及CO2等能源或能源物质和氦气等战略稀缺物资储存于深部地层中。盐岩地层是深地储能的优良地质体，是我国实施大规模储能的重要载体之一，目前已经建成金坛盐穴储气库、金坛盐穴压缩空气电站、江汉盐穴储气库等大型深地储能库。我国盐岩具有盐层薄、杂质含量高和夹层多等不利建库地质特征，给利用我国层状盐岩实施大规模能源储备带来系列理论和技术挑战。针对利用层状盐岩地层大规模储能存在的关键理论和技术难题，中国科学院武汉岩土力学研究所经过20余年的持续攻关，在实验装置研发、层状盐岩力学特性研究、储能库建造技术、注气排卤关键技术和运行压力优化方法等方面取得了突破，并在国内多座已建和在建的盐穴储能库中得到推广应用。利用深部盐穴实施天然气、压缩空气、石油和氢气等大规模储备是我国深地储能工程重点发展方向。深地储能涉及多场多相耦合及多尺度等复杂情况，亟需开展储能介质多尺度运移、储能地质体性能演化、深地储能智能建造、深地储能智慧运行等方面的研究，破解制约我国深地储能技术瓶颈中的关键科学问题。深地储能是岩土工程、工程地质和能源储备等学科深度交叉融合的突破口，有望形成新的专业学科。

Abstract：Deep underground energy storage refers to the storage of energy resources such as petroleum，natural gas，hydrogen，compressed air and CO2，and strategic scarce materials such as helium in deep formations. Rock salt formation is an excellent geological host body for deep underground energy storage. Using rock salt formation for energy storage is an important development direction for large-scale energy storage in China. At present，Jintan salt cavern gas storage，Jintan salt cavern compressed air energy storage power station，and Jianghan salt cavern gas storage，etc.，have been constructed. Rock salt formation in China has some unfavorable geological disadvantages for the energy storage，such as thin salt layers，high impurity content and many interlayers，which take a series of theoretical and technical challenges for large scale energy storage. To overcome these theoretical and technical challenges，the Institute of Rock and Soil Mechanics CAS has carried out continuous researches for more than 20 years. Many breakthroughs were obtained，such as experimental device research and development，mechanical properties of bedded rock salt，construction technology of salt caverns，first debrining technology，and operating pressure optimization technology，etc.，which have been used for guiding the construction of several salt cavern storages in China. Large-scale storage of natural gas，compressed air，petroleum and hydrogen by deep salt caverns is one of the key development directions of deep underground energy storage in China. Deep underground energy storage involves complex situations such as multi-field multi-phase coupling and multi-scale. It is urgent to carry out researches on multi-scale migration of energy media，performance evolution of geological host body，intelligent construction of deep energy storages and smart operation of deep energy storages，so as to solve the key scientific problems restricting the technical bottlenecks of deep underground energy storage in China. Deep underground energy storage is the breakthrough of deep cross fusion of geotechnical engineering，engineering geology and energy storage，and is expected to form a new professional discipline.

Key words： rock mechanics deep underground energy storage rock salt formation natural gas compressed air energy storage
