| 摘 要： | 重点分析了渤海形成大油田的石油地质条件。渤海晚期构造活动强,是渤海湾盆地渐新世—上新世的沉降—沉积中心,由此决定了它比周边陆地油区多出了东三段烃源岩,上覆馆陶—明化镇组沉积厚度大,使东三段生油岩深埋、成熟;东二段大型三角洲发育,明化镇组盖层条件好,这些为大油田形成提供了良好的储-盖组合;凸起上大型的潜山-披覆背斜和大断层下降盘的逆牵引背斜,数量多、面积大,为石油聚集提供了场所;基底不整合面及控凹大断层是运移的优质通道,为石油的汇聚提供了条件。以上优越的源、储、盖、圈、运等条件,奠定了渤海大油田形成的基础。 |

| Abstract: | The geologicical conditions of Bohai Oilfield were mainly analyzed.Bohai characterized strong late tectonic activity,and it was sedimentation-deposition center of the Bohai Bay Basin in Oligocene-Pliocene period,which made it develop more source rocks in east segment than in the surrounding land areas.Deposition thickness is large overlying Guantao-Minghuazhen making the Third Member source rocks deep buried and mature.The East Second Member developed large delta with good Minghuazhen covering condition,and... |
