摘要
20 0 2年底中国四川盆地天然气累计探明储量已达 76 0 0× 10 8m3 ,天然气年产量却只有 10 6× 10 8m3 ,其中商品气为 10 1× 10 8m3 ,不能满足市场需求。究其原因是 ,四川盆地天然气大多高含硫 ,而脱硫厂建设又滞后。文章通过分析四川盆地所产天然气在四川、重庆、云南、贵州 4省市的地区和行业消费结构 ,以及经济增长对天然气的需求状况 ,指出了未来几年四川盆地天然气供需基本形势 :建材、CNG、民用用气将继续保持增长势头 ,而甲醇生产和发电用气有很大潜在市场 ,化肥的尿素生产用气则存在下降的可能。但从整个天然气供需态势看 ,2 0 0 5年前天然气产量的增长将低于需求量的增长 ,市场将继续保持供不应求的局面。随着脱硫厂从 2 0 0 5年开始陆续建成投产 。
The gas cumulate proved reserves had reached to 7 600 × 10 8m by the end of 2002 in Sichuan Basin. But the gas production was only 106 × 108m/a, the marketable gas was 101 × 10 8m, which can't meet the market demand. The reason is the most of gas produced from Sichuan Basin contains sulfur, and the construction of desulfuration plants delays. Analyzing the regional and industrial consuming configuration of the gas produced from Sichuan Basin in Sichuan, Chongqing, Yunnan, and Guizhou, and the gas demand along with economic growth, the article states the basic situation of gas demand in a few coming years; The increasing momentum will be kept for the fields of building materials, CNG, residential use, etc. There is great market potential in the fields of methanol producing and power generating. The demand may decrease for carbamide producing. But in view of gas supply-demand situation, the gas production increase will always be lower than the gas demand increase, so the gas market will remain the situation, i. e. the demand exceeds the supply before 2005. Then, the contradiction of gas supply-demand will be relieved as the desulfuration plants are set up and put into operation one by one after 2005.
