Abstract: 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.
