摘要
深层地下储能是利用深层地下空间进行大规模储能,是提供稳定的清洁能源供应、实现石油战略储备、促进天然气调峰的重要途径。岩盐地层是大规模储能的理想地质介质,而中国盐岩资源丰富,储能空间严重短缺。与其他国家的盐丘相比,中国的盐类岩层为典型的湖相层状盐岩,具有层薄、杂质含量高、夹层多的特点。盐类储层大规模储能的发展面临着科学和技术上的挑战,包括:①考虑多场多相耦合的影响,建立储能洞室周围岩体的多尺度递进破坏和表征方法;②了解大型地下深层蓄能洞室渗漏演化规律;③了解大型地下深层储能洞室的长期性能演化;④开发深层地下盐穴储能智能施工技术;⑤保证深层地下蓄能空间的长期功能。解决这些关键科技问题的关键在于为中国大规模地下深层储能的发展奠定理论和技术基础。
Deep underground energy storage is the use of deep underground spaces for large-scale energy storage,which is an important way to provide a stable supply of clean energy,enable a strategic petroleum reserve,and promote the peak shaving of natural gas.Rock salt formations are ideal geological media for large-scale energy storage,and China is rich in salt rock resources and has a major shortage of energy storage space.Compared with the salt domes in other countries,the salt rock formations in China are typical lacustrine bedded salt rocks characterized by thin beds,high impurity content,and many interlayers.The development of large-scale energy storage in such salt formations presents scientific and technical challenges,including:①developing a multiscale progressive failure and characterization method for the rock mass around an energy storage cavern,considering the effects of multifield and multiphase coupling;②understanding the leakage evolution of large-scale deep underground energy storage caverns;③understanding the long-term performance evolution of large-scale deep underground energy storage caverns;④developing intelligent construction technologies for the deep underground salt caverns used for energy storage;and⑤ensuring the long-term function of deep underground energy storage spaces.The solution to these key scientific and technological problems lies in establishing a theoretical and technical foundation for the development of large-scale deep underground energy storage in China.
