四川盆地天然气勘探开发技术进展与发展方向

四川自西汉时期就发现并利用了天然气，川渝石油人在四川盆地建成了新中国成立后的第一个天然气工业基地。为推进“建设300亿战略大气区和一流天然气工业基地”的工作目标，首先分析了四川盆地天然气工业现状：①川渝地区经济社会对天然气依存度越来越高；②天然气勘探开发配套技术日臻完善；③地面系统综合配套能力大幅提高；④资源基础更加雄厚，产量快速增长。总结了中国石油西南油气田公司近期在该盆地天然气勘探开发工作中所取得的技术进展：①岩性气藏勘探技术取得重大突破；②深层礁滩高含硫气藏开发技术攻关成效显著；③形成须家河组气藏一类区开发主体配套技术；④钻完井及其配套技术攻关取得重要进展；⑤老气田稳产和提高采收率配套技术进一步完善。进而指出了下一步的工作方向：在开江-梁平海槽两侧，须家河组，石炭系、嘉陵江组等老区层系，震旦系-下古生界新领域等勘探开发主攻方向，深入开展深层礁滩气藏、低孔渗碎屑岩气藏、高含硫气田、老气田勘探开发技术攻关，并以页岩气勘探开发为重点，全面展开非常规天然气的勘探开发工作，推动该盆地天然气快速增储上产，再上新台阶。

Technical progress and developing orientation in natural gas exploration and development in the Sichuan Basin

Natural gas was first discovered in Western Han Dynasty in Sichuan,thus the first natural gas industrial base was founded in the Sichuan Basin after the establishment of People's Republic of China.For achieving the goal of building a first-class natural gas industrial base with 300 billion m3 of annual gas productivity the strategy of which has been planned by the PetroChina Southwest Company,this paper first analyzes the present status of natural gas industry in the Sichuan Basin as follows: a.the dependen...
