| 摘 要： | 大型铲式断层往往是滚动背斜发育的重点部位,也是油气聚集的有利场所,而铲型标准断层几何形状的确定对于寻找滚动背斜意义重大。利用旋转反向次级断层切线法获得剪切角的倾向剪切技术,较准确地计算了渤海湾盆地济阳坳陷新生代铲式断层的拉张量,追踪和恢复了639剖面主干断层的轨迹。

| Abstract: | It's a significant meaning to looking for anticline trap of roller anticline through confirming geometry of normal listric a fault,poor seismic data in deeper section usually bothers researchers during their exploring process.A inclined shear technique by rotating tangent of antithetic subsidiary fault could result in more accurate extension,thus tracing fault trajectories.We have had a great achievement in tracing trajectories of listric of 639 profile in Jiyang sag. |

| Keywords: | Jiyang sag Fault trajectories Subsidiary fault Inclined shear. |
