After the decade production in the old onshore oil field, it is urgent to find the replace resources as the key to sustainable development. The home and abroad exploration practice has indicated that the negative tectonics (called as sag) would be a significant exploration area in the future while the exploration extent in positive tectonics is very high. In this paper, Banqiao sag as a case, we set up the sand controlled model for the border fault compose styles by means of comprehensive investigation of structure-stratigraphy-sand contrained by sequence framework, and then identify the lithologic trap. Based on source rock and deep reservoir condition, we consider that the deep petroleum accumulation conditions in the Banqiao sag would be beneficial to find the lithologic oil & gas reservoir.
Key words： Negative tectonics; Accumulation model; Exploration potential.
