摘要
Three kinds of interference wave investigation method were introduced. The advantages and applicability of the methods were given in LJ area, square array investigation method and production array noise recording method were used to investigate the interference wave. After analyzing the characteristics of wavefield, the high-density acquisition trace interval in LJ area was selected as 12.5 m. The results demonstrated that by using interference wave investigation methods, the spatial aliasing of main interference wave was removed and the separation of interference wave obtained good result. Meanwhile, the resolution and signal-to-noise ratio of the seismic sections were increased.
