摘要： 通过对塔里木盆地库车坳陷克拉1构造白垩系、古近- 新近系储集层录井、地层测试资料及可溶有机质特征的分析,探讨了油气的多期运移事件。克拉1构造虽然没有成为气藏,但在其演化的地质历史过程中,却有过油气多期运移事件的发生。在整个库车坳陷,油气的多期、多阶段运移具有普遍性,这也是库车坳陷油气成藏的有利条件之一。但油气运移能否成藏的关键取决于是否存在完整的圈闭及沟通储集层与烃源岩的深大断裂,已有的气藏主要都是完整的圈闭与沟通储集层和气源岩的深大断裂有效匹配的结果。

Abstract: The logging and formation test data as well as soluble organic matter feature of Cretaceous and Tertiary reservoirs in Kela-1 structure of Kuqa depression in Tarim basin are analyzed and the multi-period petroleum migration events are discussed. The study shows that Kela-1 structure was not a gas pool, but in the course of its geological history, the multi-period petroleum migration events even occurred here. And the prevalent occurrences of its multi-period/stage petroleum migrations become one of advantageous conditions for hydrocarbon accumulation in Kuqa depression. The key factor that the hydrocarbon accumulation really occurred by the multi-period/stage petroleum migrations depended on whether there existed complete trap( s) and deep fault linked to the reservoirs and the source rocks or not, because the existing gas pools are mostly resulted from an effective match between the complete trap(s) and such a deep fault.

Key words: Tarim basin, Kuqa depression, petroleum migration, trap, organic matter
