依据地震反射特征和层序界面性质特征，对东海陆架盆地第三系进行了层序地层划分，并建立了层序地层格架．共划分出３个构造层序，７个超层序和１９个层序．以岩心成因相的精细描述及测井相分析为基础，对该盆地第三系进行了沉积体系分析．共识别出９种沉积体系，２０种沉积组合和若干种成因相．对盆地构造演化各阶段的沉积体系发育、空间展布及体系域组合等沉积响应进行了分析．以微体古生物年代化石为主要依据，结合沉积环境和沉积构造反映的古水深标志，编制了东海陆架盆地第三系海平面变化曲线．反映长周期的海平面变化有４次，短周期的海平面变化共２２次．相对海平面变化的幅度在０～１５０ｍ之间．海平面长周期反映的海侵、海退作用速度具有不对称性．以上述研究为基础，总结了盆地有利的油气生成和储集相带类型．
Based on the characteristics of seismic reflection and the characteristics of sequence boundaries, the stratigraphic division of the Tertiary in the East China Sea Shelf Basin was carried out and the sequence stratigraphic framework was established. Three tectonic sequences, seven super-sequences and 19 sequences are divided. Based on the fine description of core facies facies and well log facies analysis, the sedimentary system of the Tertiary in this basin was analyzed. Nine kinds of sedimentary systems, 20 sedimentary assemblages and several kinds of facies have been identified. Sedimentary responses, such as sedimentary system development, spatial distribution and combination of system and field, are analyzed in all stages of tectonic evolution of the basin. Based on microfossil paleontology age fossils, combined with the sedimentary environment and sedimentary structure reflect the ancient water depth signs, prepared the East China Sea Shelf Basin Tertiary sea level curve. There are 4 sea level changes reflecting the long period and 22 sea level changes in the short period. Relative sea level changes in the range of 0 ~ 150m. The long period of sea level reflects the speed of transgression and regression of sea returns with asymmetry. Based on the above studies, the favorable facies types of hydrocarbon generation and accumulation in the basin are summarized.
