| Abstract: | The formation of the Paleogene in the Chengbei fault-step zone of the Dagang off-shore area is very complex and the stratigraphic
division and correlation are relatively difficult. A method of micropaleontology-sequence stratigraphy is proposed herein.
The study considers Well Zhangcan 1 as an example to prove that the scheme of stratigraphic division is feasible by conducting
micropaleontology-sequence stratigraphy in the Guanjiapu area of the Chengbei faultstep zone. The application of micropaleontology-sequence
stratigraphy method indicates that Member 1 of the Shahejie Formation in Well Zhuanghai 808×1 and Member 3 of the Dongying
Formation of the Paleogene exist.
