摘要(Abstract)：

根据渤东低凸起及其邻区钻井和三维地震等勘探资料,采用地层展布特点、构造样式分析和构造恢复等方法,研究渤东低凸起中南段的构造形态、演化与形成机制.结果表明:渤东低凸起的形成时间为沙三段沉积末期,在东营组沉积时期定型,形成的动力来源为郯庐断裂右行走滑活动使其增压弯曲部位的岩石圈断块受到近东西向挤压应力的作用,构造演化分为孔店—沙四段沉积时期、沙三段沉积末期、东二下亚段沉积时期和新近系沉积时期阶段;构造演化通过对圈闭的形成和油气运移过程的控制,影响研究区的油气聚集成藏,并使油气在空间上呈现"断层、不整合和区域砂体联合疏导"立体成藏模式.该成果对于研究区下一步的油气勘探具有一定的指导意义.

关键词(KeyWords)：渤东低凸起;郯庐断裂;走滑断层;构造演化;油气成藏
