Abstract

Abstract: China became the largest energy producing, consuming and importing nation in the world during the 13th Five-year Plan period. The country is now under the key stage for energy transformation – “clean coal, stable oil production and increase of gas production”. The unconventional oil and gas theory and technology as well as management innovation helps China bring about a rapid petroleum upstream development towards unconventional oil and gas from conventional oil and gas. China’s unconventional natural gas production reached about 732×10⁸m³ in 2020, accounting for 38 percent of the country’s total natural gas output. Strategic breakthroughs in exploration evaluation of tight oil and shale oil were made in a number of basins, such as Ordos, Junggar and Songliao. The annual production was about 200×10⁴t in 2020. It will be an important area to keep the domestic oil production stable and growing in the future. Unconventional oil and gas industrial development is different from conventional oil and gas in terms of development conception, technology and management model. During the 14th Five-year Plan period, the efforts will be concentrated to “put shale gas into a large-scale production”, typically development of marine-facies ancient shale in South Sichuan, “make large-scale and effective breakthroughs in shale oil”, typically shale oil development of middle to low maturity and middle to high maturity, and “achieve a strategic coal-to-gas breakthrough”, typically underground coal gasification, laying a solid foundation for China’s unconventional oil and gas development. Unconventional natural gas production is likely to exceed 50 percent of the total natural gas output by 2035 while unconventional oil production will surpass 20 percent of the total crude oil yield.

摘要： “十三五”期间，中国已成为世界最大能源生产国、消费国和进口国，正处于“洁煤、稳油、增气”能源转型过程的关键时期，非常规油气理论、技术及管理创新，推动了我国石油上游业务从常规油气向非常规油气的跨越式发展。2020年中国非常规天然气产量为732×10⁸m³，占天然气总产量的38%；致密油与页岩油等勘探评价在鄂尔多斯、准噶尔和松辽等多个盆地取得战略性突破，2020年产量约为200×10⁴t，是未来国内原油稳产增产的重要领域。非常规油气产业发展具有与常规油气不同的开发理念、技术及管理模式。“十四五”时期，努力实现非常规油气以川南海相古老页岩开发为代表的“页岩气规模上产”，以中低成熟度、中高成熟度页岩油开发为代表的“页岩油规模有效突破”，以煤炭地下气化为代表的“煤制气战略突破”，夯实中国油气发展的非常规基础。2035年非常规天然气产量有望超天然气总产量的50%，非常规油产量将占原油总产量的20%。
