Wang Hongrui, Chen Degang, Zhou Kaiming, Pickup and Elimination of Residual Dynamic Correction. Geophysical Prospecting, 1997,32 (6): 872 ~ 877 In order to overcome the influence of residual dynamic correction on reducing the resolution of seismic records, this paper uses forward and backward prediction to build the model track, and according to the maximum similarity coefficient criterion The residual dynamic correction is obtained and then filtered by Butterworth filter to achieve high precision dynamic tensile correction to eliminate the influence of the residual dynamic correction and maintain the original resolution of the seismic record and make the noise generated in the superposition process Get decayed. The trial calculation and practical application of the theoretical model show that the method has a good effect.
