摘要
Combining with various geological features, the authors analyze accumulation period and the dynamic accumulation process of Zhenwu oil field by ways of structural evolution, crude oil features and fluid inclusion. The authors reach conclusion that there were two accumulation periods in Zhenwu oilfield, firstly, the second member of the Funing Formation generated, migrated and accumulated before the late of Sanduo Formation, but the next structural uplift at the late of Sanduo Formation damaged the early oil reservoirs. At the Early-Middle of Yancheng Formation, it mainly is the time of the fourth member of the Funing Formation reburied and secondary oil generation, which is the essential period of petroleum migration and accumulation. From the late of Yancheng Formation on, it is the essential period of petroleum preservation.
