摘　　要：探讨渤海湾盆地青东凹陷反转构造特征、成因及其对油气成藏的控制作用。通过对区域构造应力场调查、三维地震构造解释、构造组合样式分析、油气藏特征研究,表明反转构造是基底断裂古近纪伸展断陷期张扭性活动和古近纪末反转期压扭性活动叠加的结果,并控制形成了多种类型圈闭。基底断裂沟通了烃源岩,其古近纪末反转与烃源岩大量排烃期一致,成为油气运移的重要通道。The paper discusses the inversion structural characteristics, the genesis and the control on the oil and gas accumulation of the Qingdong sag in Bohai Bay Basin. Through the survey of the regional structure stress field, the interpretation of seismotectonics, the analysis of the structural patterns and the research of the oil and gas reservoir characteristics, it is found that the inversion structure is the result of the tension-torsion movement of the basement faults at the extension fault- depression stage of Paleocene and the compression-torsion movement at the inversion stage at the end of Paleocene, and hence controls and forms different types of traps. As the Paleocene inversion movement of the basement faults connected with the hydrocarbon source rocks is consistent with the massive hydrocarbon expulsion period, the basement faults are the main paths of the oil and gas migration.
