The structural evolution in Paleogene continental rift basin of east China and the successive sedimentary filling pattern control the trap type，the carrier system and the dynamic continuity of reservoiring，resulting in continuous reservoir distribution，ordered reservoir type and complicated hydrocarbon accumulation model characterized by vertical superposition and lateral adjacency. Through the analysis of reservoir distribution sequence of different levels of geologic unit，reservoir types in sags，second-order sequences and large-scale sedimentary systems usually distributed in an order as follows：lithologic reservoir-structural reservoir-stratigraphic reservoir. Corresponding to the macroscopic geological elements of reservoir-forming and the ordered reservoir types，the microscopic reservoir attributes，including oil-bearing saturability，displacement pressure and median pressure，show ordered-changing patterns accordingly. On the other hand，differencesexsit in reservoir distribution sequence for different levels of geologic unit of the basin，mainly include the absence of some kind of reservoir type and the unbalanced resources proportioning between different reservoir types.
