Strong reflector is widespread in the actual data analysis.The traditional description method of this kind of reservoir is based on certain time window to extract property,reservoir analysis and description directly,which greatly affect the precision of reservoir research.In this paper,with a practical example from Fuyu oil layer (T2) in Punan area of Songliao basin,in combination with the geological situation and drilling and logging data,and through the forward modeling technique,the authors analyzed the causes of T2 strong reflection and influence range.After an analysis of clear formation mechanism,the authors propose a strong reflector influence removing technology based on matching pursuit algorithm,calculation and analysis of actual seismic data.The research results show that,with the elimination of strong reflector effect before seismic attribute extraction,the prediction accuracy of the underlying layer can be greatly improved.
