Exploration Potential and Countermeasures of Lithologic & Stratigraphic Reservoir in Dongpu Sag

Through the discussion of the current state of lithologic stratigraphic reservoir of Dongpu sag and the contrastive analysis of some typical basins in China,the geological conditions favorable for the formation of lithologic stratigraphic reservoir in the sag are illustrated.The main area to explore lithologic stratigraphic reservoir is within the area of hydrocarbon generation where structural trap is not developed.The countermeasures for exploring the lithologic stratigraphic reservoir in the sag are analyzed and summarized.More attention should be paid to high-precision 3D information and reservoir characterization in order to effectively explore the lithologic stratigraphic reservoir.
