辽河滩海葵花岛构造带断裂发育特征及其与油气关系

辽河滩海葵花岛构造带发育复杂断裂体系，断裂发展主要经历了沙河街组三段沉积期－东营组二段下部沉积早期，东营组二段下部沉积晚－东营组一段沉积期，Ｎ－Ｑ等三个期次，本文根据规模，控制作用和与油气关系将断裂分为基底主干断裂，盖层主要断裂，盖层次要断裂，小断裂四个序次，断裂与油气关系密切，断裂活动控制了生储盖层之发育，在构造和圈闭形成中起主导作用，影响油气运聚与保存，最后，文章讨论了之各种圈闭之油敢勘探前景

FAULTDEVELOPMENTANDITSRELATION TOPETROLEUM IN KUIHUADAO STRUCTURE ZONEOFLIAOHEOFFSHOKEAREA

Complex fault system has been developed in Kuihuadao structure zone of Liaoheoffshore area. The development of the faults mainly went through 3 stages,namely,sedi-mentationof the third member of Shahejie Formation to early sedimentation of the lowerpart of the second member of Dongying Formation,late sedimentation of the lower partof the second member of Dongying Formation to sedimentation of the first member ofDongying Formation and N-Q.According to the scales, controls on and relations topetroleum,we divide the faults into four types:basal major fault,major superficial fault,secondary superficial fault and small fault. Faults'action controlled the development ofsource rock,reservior and cap rocks,played a leading role in the formation of structuresand traps,and affected migration,accumulation and preservation of petroleum. Finally,the prospect of traps in each area is briefly discussed in this paper.
