摘　　要：东濮凹陷兰聊断裂带的形成演化可分为两个时期 5个阶段 ,即中生代、新生代时期和挤压、初裂、强裂、萎缩、余动阶段。兰聊断裂带油气圈闭类型多 ,根据油气地质特征、圈闭所处位置、遮挡条件和产状等 ,可分为鼻状构造和半背斜构造、上翘物性遮挡岩性圈闭、潜山圈闭、礁体圈闭、地层不整合圈闭、地层超覆圈闭、古河道岩性圈闭及推覆构造圈闭 8种类型 ,而油源丰富、油气运移条件好、通道多及水下扇砂体和构造控制则是油气聚集的主要因素。The formation and evolution of Lanliao fault belt in Dongpu Depression may be divided into two periods and five stages such as Mesozoic and Cenozoic Periods,and compression,iniital fracture,strong fracture,shrinkage and after vibration stages.Hydrocarbon trap types in Lanliao fault belt are various.According to oil and gas geological feature,the location of traps,the screening condition and the occurrence,the trap types could be divided into eight kinds,i.e.the nose structure,half-anticline,the upwarping lithologic trap,buried-hill trap,stratigraphic unconformity trap,the reef trap,the paleochannellithological trap and the nappe structural trap.Rich oil and gas source,favourable hydrocarbon migration conditions,the multi-passage,the subaqueous fan sandbodies and structure-controlling are the major factors of hydrocarbon accumulation.
