21世纪初叶四川盆地大中型气田勘探战略研究

研究了四川盆地的天然气资源基础,认为该盆地大中型气田的勘探潜力较大。立足未来5～10年该盆地天然气开发的战略布置,提出了勘探的战略对策。

THE RESEARCH ON EXPLORATION STRATEGY OF MAJOR GAS FIELDS IN SICHUAN BASIN IN THE NEXT INITIAL GENTRURY

After research the total nature gas resources in Sichuan Basin, we can see that the ratio of proved reserves is only seven point seven five percent, and the exploration potential is large. There are six exploration areas of major gas fields in Sichuan Basin. First is the Precambrian weathered residuum on the leshan-longnushi uplift in the middle of Sichuan Basin, second is the Alexandria xiaoheba sand in the east southern of Sichuan, third is the caboniferous structural slope traps, fourth is the ochoan continental shelf margin reef around kaijing-liangping trough in the east of Sichuan, fifth is the Scythian feixianguan Oolite beach in east Sichuan, sixth is the Jurassic and the Rhactic exploration areas in the west of sichuan. There are much natrue gas resource in these six exploration areas, but the major gas exploration traps in no enough and exploration technology need to be improved for the next five to ten years, so the author draws out three exploration strategies how to keep the development ratio of nature gas industry in sichuan basin.
