Abstract

Abstract

Since the beginning of the deposition of Dongying Formation, the Bozhong depression has had the highest subsidence-sedimentation rates and the strongest late-stage (since 5.1 Ma) fault activity in the Bohai Bay basin. High subsidence-sedimentation rates have had very important "material" effects on petroleum accumulation. On one hand, both Dongying and Shahejie formations comprise effective source rocks in the Bozhong depression because of much thick overlying strata, whereas only Shahejie Formation is taken as effective source rocks in almost all other depressions in Bohai Bay basin. On the other hand, strong overpressure caused by compaction disequilibrium due to rapid subsidence and sedimentation retarded organic matter maturation especially hydrocarbon thermal destruction and delayed petroleum expulsion, which made both Shahejie and Dongying formations remain in a favorable conditions for petroleum generation and expulsion during late stage (since (5.1 Ma)). The "material effect" is a key for the rapid petroleum accumulation around Bozhong depression. The combination of strong overpressure and strong faulting during late stage controlled fluid flow as a result of episodic petroleum accumulation. Hence, such a process controls the distribution of petroleum occurring in Neogene strata.
