中文摘要:
      中国东部发育多个中新生代断陷盆地,长期处于构造伸展环境中,难以形成挤压构造样式。笔者根据高精度三维地震数据,在苏北盆地陈堡地区精细解析出一条走滑逆断层,结合生长指数法分析断层活动性,并明确其成因机制。研究表明,陈堡走滑逆断层走向近EW,倾向为S,倾角大于70°,呈高角度向南倾斜,错断了T23、T33和T04等主要反射层,表现为同沉积断层,其主要活动时期为阜宁组时期,阜三段时期活动性最强,该断层的形成与区域构造背景有关,属于走滑诱导和重力滑动共同成因。陈堡走滑逆断层对烃源岩形成、油气运移、圈闭发育都具有控制作用,认为陈9断块发育有利圈闭,勘探潜力大。
英文摘要:
      Many Meso-Cenozoic rift basins developed in eastern China, which is difficult to form the compressional structural style. This paper studies a strike-thrust fault in Chenbao oilfield of Subei Basin and analyzes its geometric characteristics and forming mechanism based on high quality 3-D seismic data. It is shown that the reflections of T23, T33, T04 were cutted by the strike-thrust fault, which strike to EW and incline to south with a high angle. The main activity periods of the strike-thrust fault were E1f era. The strike-thrust fault was formed by slide gravity and strike induction under its deep background. The source rocks, hydrocarbon migration and traps were strongly affected by the strike-thrust fault. The oil trap of Chen9 block has been evaluated as an important petroleum potential.
