摘要： 塔里木盆地轮 南低隆凝析气藏分布在奥陶系、石炭系和三叠系,属深层和超深层凝析气藏。油气地球化学特征表明为海相油、气,来源于寒武-奥陶系烃源岩。碳酸盐岩(O)和碎屑岩(C、T)储集层分2大类4个亚类圈闭组合,形成了10种类型的凝析气(田)藏。该区经历了多期构造运动的改造,油气也经历了多期成藏,形成了现今多种多样的凝析气(田)藏。轮南低隆是一个凝析油气富集的地区,也是今后继续深入勘探的有利地区。

Abstract: The condensate gas pool of Ordovician, Carboniferous and Triassic in Lunnan low uplift in Tarim basin belongs to deep and ultradeep condensate gas reservoir. The petroleum geochemistry shows its oil and gas of marine facies originated from the Cambrian-Ordov ician source rocks. The carbonate rock (O) and detrital rock (C,T) could be classified into trapping assemblages of 2 types or 4 subtypes, which allow to form 10 kinds of condensate gas pools. Such variety of condensate pools here was resulted from multi-tectonic movements and multi- stage petroleum accumulations. It is believed that Lunnan low uplift is an area with abundant condensate oil and gas, and is a favorable area for further petroleum exploration in future.

Key words: Tarim basin, Lunnan area, low uplift, condensate gas, reservoir feature
