Abstract

Abstract: Driven by the accelerated transformation of global energy structure and the strategic goal of carbon neutrality, the comprehensive utilization of deep underground space (below 500 meters)has become a crucial approach to ensuring national energy security and achieving green, low-carbon development. By reviewing the comprehensive utilization of underground space both domestically and internationally, the current status and future development directions of the "2334" foundational theory have been clarified. These include two fundamental theories:dynamic sealing of gas storage geological bodies and partitioned, differential utilization of porous medium gas storage space. Additionally, three key technologies are identified:efficient cavity construction in salt caverns, large displacement drilling and production techniques, and tripartite risk monitoring-early warning system. Three common technology development directions are highlighted:cross-scale small molecule sealing, efficient peak shaving operation, and coordinated optimization of the entire system. Furthermore, four frontier technology development directions are outlined:controllable transformation for increasing production in low permeability reservoirs, compressed air energy storage, helium storage capacity loss evaluation, and non-hydrocarbon cushion gas replacement. The utilization layout of deep underground space, characterized by "East-West collaboration and multi-energy complementation", is proposed. This includes the establishment of six gas storage centers with a capacity of 100 billion cubic meters, the dual mode of "production site + receiving" for helium storages, the construction of hydrogen storages around wind and solar hydrogen production bases, forming a "west-to-east gas and salt" pattern, and the deployment of compressed air energy storages tailored to local conditions. A comprehensive analysis shows that the scientific utilization of China’s abundant deep underground resource space can enable the efficient storage of multiple media, including natural gas, hydrogen, compressed air, and helium. This will significantly facilitate the integrative development of oil, gas and new energy sectors, serving as a strategic direction that strongly supports the enhancement of China's energy system resilience and the achievement of the "3060" dual carbon goals.

Key words: underground gas storage, underground space utilization, multi-media storage, common technologies, frontier technologies, industrial layout

摘要： 在全球能源结构加速转型与碳中和战略目标驱动下,深层地下空间(地表以下500 m以深)综合利用已成为保障国家能源安全、实现绿色低碳发展的重要手段。通过梳理国内外地下空间综合利用业务,明晰了"2334"基础理论技术现状和未来重点发展方向,即储气地质体动态密封和多孔介质储气空间分区差异动用2项基础理论,盐穴高效造腔、大排量钻采工艺及三位一体风险监测预警3项关键技术,跨尺度小分子密封、高效调峰运行、全系统协同优化3项共性技术发展方向,以及低渗可控改造提产、压缩空气储能、储氦库库容损耗评价、非烃垫气置换4项前沿技术发展方向;提出了"东西协同、多能互补"深层地下空间利用布局,即地下储气库打造千亿立方米级六大储气中心、储氦库形成"产地+接收"双模式、储氢库依托风光制氢基地构建"西气东盐"格局、压缩空气储能库因地制宜布局。综合分析认为,科学利用中国丰富的深层地下资源空间,可实现天然气/氢气/压缩空气/氦气等多元介质高效存储,将大大助力油气新能源融合发展,并成为有力支撑中国能源体系韧性提升与"3060双碳目标"实现的战略方向。
