| 摘 要： | 本文研究认为,秦家屯断裂主要由两条右列侧接断裂组成,形成时间较早,主要活动期为早白垩世早期,对火石岭组地层沉积厚度具有明显的控制作用。秦东断裂发育的时间相对较晚,主要活动期应在登娄库期-泉头期早期,具有较明显的走滑特征。该断裂从早期已形成的两条秦家屯断裂之间切过。这两条断裂对该构造部位油气的运移和聚集具有重要控制作用。

| Abstract: | Based on our research,Qinjiatun fracture was composed by two right-lateral fractures,and formed in early Huoshiling period which controlled sedimentary thickness of the Huoshiling formation.While Qindong fracture formed relatively later,the major active stage is Denglouku-early Quantou period,which cut the early formed two right-lateral Qinjiatun fault,Qindong fault is a typical strike-slip fault.Qinjiatun fault and Qindong fault played a decisive role for the hydrocarbon migration and accumulation in this region. |
