| 摘 要： | 塔里木盆地塔中北部斜坡带奥陶系海相碳酸盐岩油气勘探取得了重大突破,发现了台缘坡折带礁滩复合体大型凝析气藏和台内岩溶风化壳大型油气藏。利用有机地化指标与构造沉积演化紧密结合对有效烃源岩及成藏过程的研究取得了较好成果,但随着勘探的纵深发展,流体分布复杂的问题日趋突出,通过天然气组分以及相关同位素等分析化验数据,进行塔中北部斜坡带奥陶系油气成藏研究,建立了"三期成藏、两期调整,早期成油、晚期注气,复式聚集、普遍含油"成藏模式,明确了塔中天然气以原油裂解气为主,强调晚期气侵是形成塔中大型天然气田的关键。

| Abstract: | In the north of the Tazhong Area in Tarim Basin, a large condensate pool of reef-flat facies and a large karst weathering crustal oil-gas field have been discovered, which demonstrates a breakthrough in the oil-gas exploration in carbonate rocks of Ordovician marine facies.By using organo-geochemical indexes combined with the analysis of the evolution of tectonic-sedimentation some good results have been achieved in the study of the effective hydrocarbon source rock and the accumulation process.But as the e... |
