摘　　要：受郯庐断裂带的影响,辽东湾地区发育多条大型走滑断裂,主断裂与伴生构造形成多种构造样式,已探明的油气藏大多沿着走滑断裂带分布。利用最新的地震剖面资料,分析辽东湾地区走滑断裂系统的发育特征及其对油气成藏的影响。研究表明,走滑断裂不仅能直接形成断块、背斜、断背斜等圈闭,还能间接诱发泥底辟构造,影响烃源岩的成熟演化、储层发育、油气运移及保存。Due to the influence of Tanlu Fault Zone,several large strike-slip faults were developed in Liaodong Bay Area.Many kinds of structural styles were created by the main faults and associated structures.The proven oil-gas reservoirs were distributed along the strike-slip fault zones.The latest seismic sections were used to analyze the features of strike-slip fault system and its effect on hydrocarbon accumulations.The study result shows that strike-slip fault can not only directly form fault block,anticline,breaking-anticline traps and induce a mud diapir structure indirectly,which would affect the maturity and evolution of source rocks,development of reservoirs,migration and preservation of hydrocarbon.
