摘要
四川盆地是世界上最早发现与利用天然气的地区,新中国现代天然气工业也在此起步。经过近70年的发展,已建成上中下游产业链完整的天然气工业体系,天然气产量领跑全国半个世纪,在改善一次能源消费结构、建设“美丽中国”的发展进程中发挥了重要作用。“十三五”全国油气资源评价结果表明,四川盆地天然气资源量达39.94×10^(12) m^(3),居我国各含油气盆地之首,并且探明率仅15%,仍处于勘探早中期,天然气勘探开发潜力大;2020年该盆地天然气产量为565×10^(8) m^(3)(包括在该盆地作业的中石油、中石化两家生产企业),居全国主产气区之首。未来10年,从发展环境看,国家提出了新的发展理念,在成渝地区推动双城经济圈建设,四川盆地将建成年产气1000×10^(8) m^(3)的国家天然气战略生产基地,标志着该盆地天然气工业发展进入了新的黄金时期。从发展潜力看,深层、超深层海相碳酸盐岩气藏,深层页岩气,陆相致密砂岩气是未来该盆地寻找大气田的重点勘探开发领域,按照“海陆并举、常非并举、构造与岩性并举”的思路,依托理论技术进步,加强核心技术攻关,未来将进入天然气资源品质不断提升、产量持续快速增长的大发展期。同时,利用大发展的契机,突破工作对象日趋复杂、管网输配系统不够完善、高端高附加值产业欠缺的发展瓶颈,在低油价常态化的形势下,构建天然气“产运储销”业务协同发展、全产业链创新创效的新型工业体系。总之,四川盆地天然气工业将迎来新的高峰增长期、高质量发展期,天然气年产量规模将超过1000×10^(8) m^(3),2030年中国石油西南油气田公司天然气年产量将达到800×10^(8) m^(3),成为世界一流的天然气生产供应基地。
The Sichuan Basin is the earliest natural gas discovery and utilization area in the world,where the modern natural gas industry of New China started.Through nearly 7 decades of development,a natural gas industrial system with complete upstream,middle and downstream industry chain has been established,and its natural gas production has led the other places of China for half a century.And it has played an important role in the process of improving the primary energy consumption structure and constructing a"beautiful China".The evaluation result of national oil and gas resources in the 13th Five-Year Plan shows that the natural gas resource extent in the Sichuan Basin is 39.94×10^(12) m^(3),ranking the first in domestic petroliferous basins.In addition,the proven rate is only 15%and it is still in the early and middles stages of exploration.Therefore,the Sichuan Basin has great potential in natural gas exploration and development.The natural gas production in the Sichuan Basin in 2020 is 565×10^(8) m^(3)(including all production enterprises of PetroChina and Sinopec in the Sichuan Basin),taking the first place in domestic major gas producing areas.Speaking of the next decade,the state puts forward new development concepts from the perspective of development circumstances.The construction of Chengdu–Chongqing economic circle will be promoted and a national natural gas strategic production base with yearly gas production of 1000×10^(8) m^(3) will be built up in the Sichuan Basin,which marks a new golden development period of natural gas industry in the Sichuan Basin.From the perspective of development potential,deep and ultra-deep marine carbonate gas reservoirs,deep shale gas and continental tight sandstone gas will be the key exploration and development fields to search for giant gas fields in the Sichuan Basin.It is recommended to strengthen core technology researches according to the thoughts of"simultaneous development of marine and continental,conventional and unconventional,structural and lithologic"and relying on theoretical and technological progress.In the future,it will enter a great development period when the quality of natural gas resources will be continuously upgraded and the production rate will be increased continuously.In the meantime,take advantage of the opportunities of great development to break through the development bottleneck of increasingly complex work objects,incomplete pipeline network system and insufficient high end and high additional value industries.Under the situation of normalized low oil price,construct a new-type industrial system with the coordinative development of natural gas production,transportation,storage and marketing and the innovation and efficiency improvement in the whole industrial chain.In conclusion,the natural gas industry in the Sichuan Basin will pace in a new peak growth period and a high-quality development period in the next decade,and its yearly natural gas production will exceed 1000×10^(8) m^(3),and the yearly natural gas production of PetroChina Southwest Oil&Gasfield Company will reach 800×10^(8) m^(3) in 2030.Obviously,the Sichuan Basin will be a world-class natural gas production and supply base.
