Abstract：New k-x and τ-x wave field transforms are put forward,which transform wave field from τ-x domain into k-x or τ-x domain. In the new domains,direct and surface wave fields etc. are nearly parallel each other. If the extracted strong noises are inversely transformed into t-x domain and removed from the original seismic section,the effective waves can be’ fully retained in the seismic section,without noise left. This method never damages the seismic waves outside a noise-contaminated area. This transform only involves coordinate transformation,without amplitude changed. It can be used in partial area.
