| 英文摘要 | The reflect angle can be computed by the combination of the formation dip angle with the incident angle field gotten with the proposed one-way wavefield continuation method. We propose a ADCIGs (Angle Domain Common Image Gathers) generation scheme for one-way wave equation shot-record migration methods. We overcome the imaging amplitude error resulting from the diversity of shot coverage by employing the amplitude-preserved deconvolution imaging conditions and taking account of stacking shot number. Comparison with other ADCIGs generation schemes based on spatial or time shift imaging condition, the proposed scheme is free of huge memory requirement, expensive computation cost (i.e. the additional computational cost of the proposed ADCIGs generation scheme can be omitted in contrast to that of the depth migration) and amplitude error resulting from the uneven shot coverage. The examples present here demonstrate that the ADCIGs generated by the proposed scheme supply the accurate AVO amplitude characteristics for prestack inversion. Furthermore, the residual NMO correction and mute can be easily applied on the produced ADCIGs, which lead to high frequency component enhancement and higher S-N ratio of one-way wave equation prestack depth migration section. |
