摘要： 塔里木盆地海相油气具有多期成藏、晚期调整的特点。晚期调整再成藏是塔里木盆地海相油气藏形成的一种重要方式,其形成的次生油气藏是塔里木盆地海相油气藏的一大类型,喜马拉雅运动期是早期油藏发生调整的主要时期,古隆起顶部是调整再成藏的主要部位。已发现的喜马拉雅运动期海相油藏主要是由晚海西运动期油藏调整再形成的次生油藏,它们主要分布于塔北隆起中生界以及塔中隆起中央断垒带石炭系。因此,寻找大中型海相原生油气藏,应以构造相对稳定的继承性古隆起特别是古斜坡区为重点,隆起高部位则是寻找次生油气藏的主要地区。

Abstract: The marine hydrocarbon accumulation in Tarim basin is characterized by multi-period accumulations and late adjustment. The late adjustment and re-accumulation is an important type of its petroleum accumulation; secondary reservoirs formed by adjustment of late accumulation is a significant style of it; and Himalayan (Cenozoic) and top of paleo-uplift are the major period and area of adjustment and re- accumulation respectively. The discovered Himalayan oil reservoirs are mostly secondary ones formed in such a way of late Hercynian reservoir re-accumulation,which mainly distribute in Mesozoic reservoir of Lunnan uplift and Carboniferous reservoir of the Central Tarim uplift. Therefore,to search for large- and medium-scale marine primary hydrocarbon reservoirs should highlight the relatively stable and inherited paleo-uplifts and paleo-slopes, whereas the uplift highs are the major areas for formation of secondary reservoirs.

Key words: Tarim basin, craton, marine facies, reservoir, Himalayan, primary reservoir, adjustment
