摘要
At Chengbei area of Dagang beach-sea region are developed Paleogene strata of Es3 to Ed1. The strata are abundant with biofossils, such as ostrcoda, gastropod, charophyta, sporopollen and alga. According to the fossils sediments in the area are divided into 5(A, B, C, D and E) biofacies which are correspondent to river-dalta plain and swamp, lake shore,shallow lake, shallow-bathysal lake and abysmal lake sedimentary facies respectively. Geological exploration in the area reveals that oil reserviors are developed under lake shore, shallow lake, shallow-bathysal lake environments are flourished and barreler.
