摘要:
辽河东部凹陷由于潜在的油气资源和复杂的构造条件（郯庐断裂穿过此凹陷），走滑活动及其对构造圈闭的控制作用对于揭示郯庐断裂北段新生代的活动及渤海湾盆地的油气勘探有重要意义。以大平房地区为实例，根据地震、钻井和测井资料，揭示了大平房地区存在走滑构造活动的行迹，包括平面上的雁列构造及其对火山岩分布的影响，剖面上的负花状构造样式及断层倾向和背斜轴向沿构造走向的变化。发育的荣兴屯走滑断裂控制并改造大平房断背斜的构造格局，东营组二段沉积开始，致使地层反转，形成透镜状地层。荣兴屯走滑活动产生的构造圈闭具有纵向分段、平面分带的特征。
Abstract:The eastern sag in Liaohe Depression bears potential oil and gas resources and is located in the Bohai Bay Basin with the Tanlu fault crossing through the Depression. In-depth investigation of strike-slip activities and their controls of structural traps will have a great significance for Cenozoic activity of northern Tanlu fault and hydrocarbon exploration in Bohai Bay Basin. In this study, Dapingfang area was taken as an example to recognize strike-slip faults and their characteristics of development on the basis of seismic data, drilling data and logging data. The study included en echelon structures in plane and their control of volcanic rock, negative flower structures in profile as well as the changes of fault dip and axial anticline along the structural strike. Rongxingtun strike-slip faults controlled and transformed Dapingfang anticline structural pattern, making strata reverse since the appearance of the second member of Dongying Formation (E3d2), as"lentoid". Rongxingtun strike-slip activities formed structural traps, which were character-ized by planar belt and vertical segmentation layout.
