摘要: 位于我国西南滇西褶皱带上的云南景谷盆地为晚第三纪的残留盆地,在其中发现的大牛圈油田所产原油与源岩有机地球化学分析证明,景谷盆地所产原油为典型的低熟油.目前该油区含油面积为0.224km2,合计探明储量可达30余万吨.古生物化石组合表明该盆地为正常淡水湖盆,水生生物与陆生生物混合成为景谷盆地的主要成烃物质.景谷盆地低熟石油的研究,对于整个云南乃至滇黔桂地区的油气勘探都将起到积极的推动作用.

Abstract: The Jinggu Basin is a residual basin in age of Neogene where located fold zone of southwest Yunnan,South China.Analyses and research,including oil physical and organic geochemical features,on the oils produced from Da Niuquan Oilfield and source rocks in this basin show that the petroleum in the Jinggu Basin is typical low matured oil.Up-to-date,about 0.224km2 area has been proved having oils and the proved reserves is up to 300,000t.It is proved by fossil assemblage that Jinggu Basin is a normal freshwater lake and the major hydrocarbon generating material should be mixture of hydrobios and genobenthos.The researches about the low matured oils in Jinggu Basin should have a positive factors for petroleum exploration in the all areas including Yunnan,Guizhou and Guangxi three provinces in South China.

Key words: Jinggu Basin, low maturied oil, geochemistry index
