摘要
Through studying the structural evolution and source rock for the first member of Shahejie Formation in Dongpu Depression,it is found that the grey mudstones are not only stable distribution in this region,but also are good hydrocarbon source rocks.The source rocks near the center of Qianliyuan Sag,Haitongji Sag aned Menggangji Sag become mature with the increase of buried depth in Neogene,having good hydrocarbon-generating condition.Study on the burial history of the first member of Shahjie Formation shows that accumulation stages is Minghuazhen depositional stage to today.The accumulation process of autogeny reservoir for the first member of Shahejie Formation in Liuzhuang is defined through studying oil and source rock correlation,reservoir and cap rock,oil and gas migration and accumulation and reservoir type.Accumulation modes of autogeny hydrocarbon reservoir are established,which are proximal accumulation,broken-sand double controlling and high position enrichment.Reservoir scale is small,but quantity is large.This achievement is important to oil-gas exploration of the first member of Shahejie Formation in Qianliyuan Sag,Haitongji Sag and Menggangji Sag in Dongpu Depression.
