| 摘 要： | 东濮凹陷三春集地区下第三系隆起带各高点勘探效果较东翼斜坡带差，但具备形成隐蔽油气藏的地质条件，该地区沙四上亚段－沙三下亚段烃源岩晚第三纪早中期产烃规模有限，生成的油气沿着断层向固阳洼陷西侧运移，在春东断层下降盘中的反向屋脊岩性圈闭中富集。通过石油地质综合研究，预测固阳洼陷西侧为三春集构造带陷蔽油气藏滚动勘探的有利地区。图3参2（张建军摘）。 |

| Abstract: | The structural zone of Paleogene in Sanchunji of Dongpu Sag is complex and the exploration of the high in the uplift is worse than that of the east slope, thus subtle reservoir may be formed in this area. During the early-mid Tertiary, the Lower Tertiary structure was fixed, oil and gas generated by the source rock of Upper Sha4(Es_4)-Low Sha3(Es_3) migrated to the west of Guyang depression through fault, but the amount of hydrocarbon generated is limited, and accumulated in the lithologic trap of reverse roof in downthrow block of Chundong fault. It is predicted that predict this structural zone is favorable for progressive exploration for subtle reservoir. |
