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。
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.
