摘　　要：与复杂走滑断裂带相伴生的断鼻、断块构造是油气聚集的有利场所。走滑断层两侧地层结构变化大，垂向断距小或无断距，断层识别和组合比较困难。针对这一问题，在对胜利油区辽东探区构造和断层特征分析的基础上，采用了多尺度相干技术、边缘检测技术和多信息叠合相干技术等地球物理方法对走滑断裂带的断层进行了识别。结合地质分析认为新的断层组合更加合理，解释精度明显提高。应用新解释成果重新评价了研究区的含油气规模，其中胜顺1块的石油地质储量达557×10^4t，其南部断块的石油地质储量为133×10^4t。The fault nose and fault blocks of complex strike slip fault zone are the favorable place for oil and gas accumulation.Stratigraphic structures on two sides of the strike slip faults are of great variety,vertical fault throw is small or no,and fault identification and combination is rather difficult.Based on the analysis of structural and fracture characteristic in Liaodong exploration area,geophysical methods,such as the technique of multi-scale coherence,edge detection,multi -information coherence,were applied for identifying the strike slip faults.Geology analysis shows that new fault combination is more reasonable and the interpretation accuracy may improve obviously.The new results were applied to reevaluate the hydrocarbon-bearing scale in the research area,among them,OOIP in Shengshun1 block and southern fault block is up to 557×10~4t and 133×10~4t respectively.
