Abstract: Based on the study of the distribution law of basin peripheral stratigraphic reservoirs in Jiyang Depression and the analysis of main accumulations-controlling factors and with adoption for the mindset for combination of qualitative analysis and quantitative assessment, the method for multi-level assessment of main accumulations-controlling factors was established on the basis of four geological conditions of conducting, storage, trap and reservoir. Of those, the condition of the conducting system highlighted the controlling effect of sourcing faults on accumulations of basin peripheral stratigraphic targets. Assessment of direct cap-rock thickness and top basement condition was introduced into the storage condition. Meanwhile, the standards for integrated assessment of the basin peripheral stratigraphic trap was established on the basis of conventional assessment of exploration targets. Establishment of these standards is of certain guiding significance to assessment and selection of basin peripheral stratigraphic exploration targets in the rift basins in China's eastern part
