摘　　要：对辽河盆地东部葵花岛油田构造特征进行了系统分析,指出研究区断裂构造具有幕式活动的特点,构造类型以伸展走滑为主,主控断层是燕南断层。研究区断层产生于沙河街组沉积末期,东营组二段沉积期断层活动强烈,东营组沉积末期以后,断层活动强度逐渐减弱。构造控制着油气的分布,背斜高点及早期长期发育的油气源断层附近是油气富集的地区。The systematic analysis of structures in Kuihuadao oilfield in eastern Liaohe basin shows that the faulting fractures in studied area are characterized by multi-stage activities. The structural types are dominated by extension and strike-slip, and Yannan fault is a key controlling fault. The faults are formed in the late depositional stage of Shahejie formation, and active in depositional stage of Dongying-2 member and gradually weaken in late Dongying depositional stage. Therefore, the oil-gas distribution in this area is controlled by the structures. The hydrocarbon enriched areas could be in the high of anticline and near the early and long-term developed faults liked with oil source.
