摘要
黄骅坳陷早第三纪介形类化石丰富、含8个组合、5个亚组合和1个化石分布段。其中,含化石属种和个体数量丰富的组合与油气生成,特别是与生油岩类型有密切关系。
Ostracodes fossils are prolific in Palaeogene in Huanghua depression. There are 8 as-semblages, 5 subassemblages and a fossiliferous rock member. Among them, those assem-blages with a large number of genera and species or abundent individuals have a positive cor-relations with petroleum generation. There are mainly two source beds in this depression. The first one, the source beds with Eucypris Wutuensis assemblage, being continental fresh shallow water deposite is the major source beds for oilfields in the South part. The secondone, source beds containing Huabeinia chinesis assemblage, being continental brackish deep water deposit, are the main source beds for oilfields in the North and Middle parts.
