A study of residual moveout correction method for P wave of HTI media
摘要
Abstract
With the development of 3D seismic exploration techniques, the study of seismic wave propagation theory in anisotropic media is going deeper.Without considering the impact of HTI media, prestack CMP trace gathers still remain "sinusoidal" residual moveout, the traditional velocity analysis and NMO based on Dix time difference formula can''t meet the requirements of precision.By drawing from statistics residual static correction reference track cross-correlation and minimum variance method, and combining the feature of HTI media, propose a method of correction of statistical anisotropy residual moveout based on reference trace.By extracting and revising the anisotropic moveout to enhance quality of the stacked profile, and give a quantitative analysis of increases of vertical resolution of stacked trace.Experiment result shows that methods of calibration of statistical anisotropy residual moveout eliminate residual moveout caused by anisotropy, and increase the vertical resolution, and then enhance the quality of stacked profile obviously.关键词
