基于2D反褶积成像条件的保幅叠前深度偏移
Preserved amplitude prestack depth migration based on 2D deconvolution imaging condition
摘要
Abstract
In order to adapt for the exploration and development of complex structures and lithologic hydrocarbon reservoirs, a preserved amplitude prestack depth migration method based on 2D deconvolution imaging condition was presented, implementing preserved amplitude split step Fourier prestack depth migration based on 2D deconvolution imaging condition. First, the receiver wavefield was deconvolved by the source wavefield in shot-time dimensions. Then the zero lag results were extracted to form the imaging profile commanding the consistency of time and shot position. The numerical results show that this method not only enhances the imaging energy of weak imaging areas where the folds are not full, but also improves the imaging quality of deep target layers.关键词
