摘　　要：断层阴影在地震剖面上表现出的成像畸变直接影响到构造落实、储量评估、井位部署等,因此正确认识断层阴影现象显得尤为重要。目前,对断层阴影的研究多局限于对构造形态的研究,却忽视了振幅能量的变化规律分析。基于此,这里采用正演模拟技术,从构造形态和振幅能量两个方面进行研究,进一步完善了断层阴影的识别技术体系。该研究方法在涠洲W油田储量研究的实际应用中取得了较好的效果,表明该技术对断层阴影的识别具有一定的借鉴意义。The imaging distortion phenomenon caused by fault shadow on the seismic section directly affects the structure implementation,reserve assessment,well location deployment,etc.,so it is particularly important to correctly understand the fault shadow phenomenon.At present,the study of fault shadows is mostly limited to the study of structural morphology,while to ignore the analysis of the variation law of amplitude energy.Based on this condition,forward modeling technology is used to study from two aspects:structural morphology and amplitude energy in this study,it further improves the identification technology system of fault shadows.The research method has achieved good results in the practical application of the reserves research in WeiZhou W oilfield,indicating that the technology has certain guiding significance for the identification of fault shadows.
