Abstract: The method of time window energy ratio is used to transform the original channel wave records. Then the common scattering point gathers are extracted from the converted channel wave records. Based on the common scattering point gathers, the scattering wave imaging method based on the equivalent offset is used for imaging. The simulated channel wave records show that after the feature transformation, the resolution of the channel wave signal is improved, the reflected channel wave is easier to identify than that before the transformation, and the imaging results can accurately reflect the location of the abnormal structure. This method is applied to practical channel wave recording. The results show that the scattered channel wave imaging based on the characteristic transformation of time-window energy ratio can focus the abnormal energy better, and the reflection channel wave imaging is better.
