摘要
The exploration experience in the Beizhong sub-Depression reveals that “residual” and “superimposed” features may be the key factors that result in oil-gas richness in such a small rift. Numerous small residual superimposed sub-depressions are developed in Mesozoic rift basins that are commonly distributed in Northeast China and Northeast Asia, they may have oil accumulation preponderance similar to the Beizhong sub-Depression and are,therefore, likely to be new targets for further exploration.
