- W2352585768 abstract "In order to improve the accuracy of the structural images in the fracture zone of the south No.1 and No.2 mining block in Guqiao Mine,a study was conducted on the time deviation images of the seismic exploration before 3D stacking.With the analysis on the geological information and the original seismic information of the exploration area,the preserved amplitude processing method was applied to obtain the channel collection of the high signal and noise ratio before the stacking.The joint reflection point channel collection after the deviation was applied to iterate and revise the mean square root after reversed correction.Then an accurate mean square root velocity field was established.The suitable deviation displacement algorithm and the different deviation parameters including the deviation borehole diameter,stretching operator,anti-aliasing operator and others were selected.Finally the time deviation before the stacking was completed.The results showed that the cross section obtained and the time deviation after the stacking would be more obvious in comparison with the lateral continuity,the signal and noise ratio was improved and the deviation profile and the borehole exposed condition could be highly met.The time deviation before stacking could be specially suitable to process the 3D seismic information of the small with fault structural relatively compacted under the complicated geological conditions in coal mine." @default.
