| 摘 要： | 济阳坳陷为一典型北陡南缓的箕状断陷盆地,其各凹陷北部的强断裂活动造成北断南超、北陡南缓的构造格局。以东营凹陷北坡为例,盆倾断裂发育,切割潜山顶面呈阶梯状,断裂旁侧沉积较厚,常发育褶皱构造。断裂上升盘遭剥蚀,下降盘发育一系列扇体,为油气聚集的有利场所。 |

| Abstract: | Jiyang depression is a typical fault depression basin with steep dip angle in the north limb and gentle in the south. All of its four sags have the similar structure pattern. Take the north slope of Dongying sag as an example. Basin-dipping faults are developed well and cut the surface of the buried hill into echelon form. The side of the fault is a deposition center and folds develop well. The upthrow-side of the fault is eroded and the downthrow-side have a series of fan systems. The fan system is a good place for hydrocarbon to accumulate. |
