高邮凹陷泰州组油气运移及成藏

Oil-Gas Migration and Accumulation of Taizhou Formation in Gaoyou Depression,Subei Basin

在前人研究基础上,运用烃类包裹体,并结合地层构造、圈闭特征等对泰州组油气运移时间、期次及成藏模式进行了研究。结果表明:泰州组油气生成、运移、成藏时间主要在三垛时期;而运移成藏模式主要有储层侧向运移、断层垂向运移和储层-断层共控3种。

Migration time, trapping history and accumulation model have been studied, based on fluid inclusions, analysis of strato-structure and trap features. It was concluded that three episodes of significant tectonic movement occured during stages of Yizheng, Wubao and Sanduo, and the Gaoyou depression formed in Sanduo stage owing to the stong block-faulting movement and favorable trap forming conditions. , There were three models of migration and accumulation in the studied area, which were reservoir-controlling lateral migrating, fault-controlling vertical migrating and composite migration controlled by both reservoir and fault.
