Despite their long history of development, some oil-rich sags still have a large quantity of residual resource in the forms of five potential play targets: undeveloped sags in the developed depression, hidden reservoir, complex fault structure, and deeply buried and small hills and some special reservoirs.

Based on the research and exploration of lithostratigraphic reservoir in the Jizhong depression of the Bohai Bay basin and Erlian basin, the hydrocarbon distribution in a continental oil-rich sag has "complementarity" feature, viz.
