摘要
The Paleogene strata from the Bohai area, which consist of the Kongdian,Shahejie and Dongying formations in ascending order, have been divided into members and sub menbers based on microfossil and 3D seismic dada.The depositional environments and climatic conditions can be inferred from the ecologic features and distributions of microfossils and lithologic characteristics. Such environmental conditions also control the formation and distribution of stratigraphic units and sub-units that contian oil source beds and reservoirs. The present research on the characteristics of the Paleogene microfossil assemblages from the Bohai area has important significance on oil and gas exploration.
