Abstract: The 13^th Five-year Plan is a remarkable five-year period for development and performance of natural gas exploration and development theory and technology in China. A series of the new exploration theories, such as the “Four Paleo” control theory of ancient marine carbonate rocks, the “Stacked Enriched Source + Structural Pumping Enrichment” natural gas accumulation principle for the foreland thrust belt, and the “Three Highs - One Protection - One Moderation” accumulation principle of shale gas, led to discovery and confirmation of three trillion-cubic-meter gas regions in the Anyue area of Sichuan Basin, the Kuqa area of Tarim Basin and the shale gas area in Southern Sichuan. The new achievements were continually made in tight sandstone gas reservoir development technology, carbonate rock gas reservoir development technology and deep-layer high-pressure gas reservoir and shale gas integrated development technology. Those technologies kept natural gas production growing continually and rapidly. China’s natural gas production reached 1925×10⁸m³ in 2020, up 9.3 percent from the previous year. Natural gas, a relatively clean fossil energy, will see an important development stage in the pursuit of the “dual carbon” strategic objective. China’s natural gas reserves and production will be continually kept growing rapidly in the 14th Five-year Plan period and even a longer future.

摘要： “十三五”是我国天然气勘探开发理论技术进展与成效最显著的5年。古老海相碳酸盐岩“四古”控藏理论、前陆冲断带“被垛式富灶+构造抽吸富集”天然气成藏理论和页岩气“三高一保一适中”富集成藏理论等勘探新理论，推动了四川盆地安岳、塔里木盆地库车和川南页岩气3个万亿立方米大气区的发现和探明；致密砂岩气藏开发技术、碳酸盐岩气藏开发技术、深层高压气藏和页岩气一体化开发技术不断取得新进展，支撑了天然气产量持续快速增长，2020年全国天然气产量达到1925×10⁸m³，同比增长9.3%。随着“双碳”战略目标的实施，天然气作为相对清洁的化石能源将迎来重要发展机遇期，“十四五”乃至更长时期内，我国天然气储产量将继续保持快速增长。
