摘　　要：松辽盆地徐家围子断陷断裂发育,徐中断裂是其东西分带的主控断层,对沉积储层分布及天然气聚集有重要影响。利用三维地震资料表征徐中断裂垂向及平面特征。不同时期徐中断层生长指数图和断裂落差图分析,得出徐中断裂为走滑断层。不同时期断裂活动强度、性质,结合古构造及分频技术刻画的扇体展布特征说明了徐中断裂控制了其两侧沉积的分布并解析了典型位置沉积演化过程。Faults are development in Xujiaweizi Depression,Songliao basin.Xuzhong fracture is the main controlling fault,has important implications on sedimentary reservoir distribution and gas accumulation.Vertical and planar characterization of Xuzhong fracture can be characterized by three-dimensional seismic data.Xuzhong fracture is strike-slip faults can be obtained from different periods fault growth index chart and fracture throw figure of Xuzhong fracture.Different period fault activity intensity,properties,combined with the palaeotectonic and frequency decomposing characterized delta fan.It shows that Xuzhong fracture control the distribution of its sides deposition and resolved typical position sedimentary evolution process.
