摘　　要：SN地区地下构造破碎,断裂发育,同时受大范围多期次辉绿岩穿层侵入的干扰和影响,致使该区大部分地震资料品质极差,断层断点不清晰,地层产状不真实,构造解释难度大。全方位角度域偏移成像不仅包括来自地下不同方位的地震-地质信息,同时也可以根据断裂在不同方位和倾角的响应,结合地质沉积特征,开展基于地质构造的地下优势倾角叠加成像,对构造复杂区断裂进行更好的识别,提高圈闭落实程度。The underground structure in the SN Area is fragmented,with developed faults.At the same time,it is interfered with and affected by large-scale and multi-stage intrusion of diabase layers,resulting in poor quality of most seismic data in the area,unclear fault breaks,unrealistic formation attitudes,and great difficulty in structural interpretation.Omnidirectional angle domain migration imaging not only includes seismic and geological information from different underground directions but also carries out geological structure-based subsurface dominant dip angle stacking imaging based on the response of faults in different orientations and dip angles,combined with geological sedimentary characteristics,to better identify faults in complex structural areas and improve the degree of trap implementation.

关 键 词：断裂发育 地层产状不真实 全方位角度域偏移 倾角叠加 圈闭落实
