摘要(Abstract)：

为了研究郯庐断裂带隐性走滑断裂特征和发育机制,确定它对油气成藏的控制作用,利用青东—莱州湾构造带高精度三维地震和钻井资料,研究隐性走滑断裂的构造特征、识别标志、断裂样式及成因机制,分析它与油气聚集关系。结果表明:研究区隐性走滑断裂可归纳5种识别标志:(1)断裂走向一致、倾向相反;(2)断裂平面变形明显、两侧地层产状突变;(3)断裂两侧地层厚度、地震相差异大;(4)断裂呈直立"栅栏状"特征;(5)断裂两侧油水关系不统一。包括潜山直立型、盆缘调节型、盆内末端型和盆内桥连型四类构造样式。该区隐性走滑断裂的大量发育与喜山运动向东挤出、太平洋板块向西俯冲的共同作用有关;隐性走滑断裂对圈闭形成、沉积特征和油气的运聚具有明显控制作用。该结果可以有效指导研究区油气二次勘探,为走滑断裂带的精细勘探提供参考。
