摘要
After brief review of the interferometry theory and relative algorithm, this paper focuses on the discussion of seismic interferometry processing and migration imaging with seismic whiling drilling (SWD) data. Seismic information excited by the drilling bit is extracted from strong noise data by F-K filter, interferometry and vertical stacking process. And then it is well imaged by Kirchhoff migration and autocorrelation migration. Combined with surface seismic stack sections around well Fan158 in Shengli oilfield, the characteristics of wave groups of SWD imaye are analyzed. The results show that deconvolution interferometry and auotcorrelation migration work pretty well in SWD data process.
