“十四五”是中国天然气工业大发展期 . (Chinese)

Among the world's 10 major gas producing countries ，only the United States ，Russia and Iran have annual gas production of 2 500×108 m3 or more. China is expected to have gas output of 2 500×10 8 m3 in 2025. There are three bases for the great development of natural gas industry in China ：Firstly ，the natural gas re⁃ sources are rich and the proved rate is low and only 8.6%，so it has the resource advantage for faster develop⁃ ment ；Secondly ，over the past 35 years ，natural gas production continues to grow ，with the growth advantage for faster development ；Finally ，since 2006，the remaining recoverable reserves of natural gas are increasing year by year ，showing the reserve advantage for faster development. In recent 10 years ，China's annual natural gas production growth rate，remaining recoverable reserves and reserve production ratio of natural gas support that China's annual gas production in 2025 will reach 2 500×10 8 m3 . Suggestions for accelerating natural gas ex⁃ ploration and development during the 14th Five-Year Plan Period：（1）Opening new exploration and develop⁃ ment fields of Carboniferous-Permian shale gas in Ordos Basin；（2）Explore three potential large gas districts with hidden coal measures in the northern Tianshan Piedown Depression ，Qaidam Depression and Xihu Sag； （3）Accelerate the development of seven large gas fields with proved reserves over 1 000×10 8 m3 ，such as Lingshui 17-2 Gas Field；（4）Increasing the drilling of gas wells and ultra-deep exploration wells.

世界 10 个产气大国中仅有美国、俄罗斯和伊朗年产量达 2 500×10 8 m3 或更多，预计 2025 年 中国年产气量将达到 2 500×10 8 m3 。中国天然气工业大发展有 3 个依据：①天然气资源丰富而探 明率低，仅为 8.6%，具有更快发展的资源优势；②过去 35 年，天然气产量持续增长，具有更快发展 的增长优势；③2006 年以来，天然气剩余可采储量逐年上扬，具有更快发展的储量优势。近 10 年的 天 然 气 年 产 量 增 长 率 、天 然 气 剩 余 可 采 储 量 和 天 然 气 储 采 比 都 支 持 中 国 2025 年 年 产 气 量 达 2 500×10 8 m3 。最后提出中国“十四五”加快天然气勘探开发的建议：①开辟鄂尔多斯盆地石炭 系—二叠系页岩气勘探开发新领域；②攻克 3 个（北天山山前坳陷、柴北坳陷和西湖凹陷）隐伏煤系 潜在大气区；③加速已探明的陵水 17⁃2 气田等探明地质储量 1 000×10 8 m3 以上的 7 个大气田的开 发；④增加气井和超深层探井的钻探。 [ABSTRACT FROM AUTHOR]
