Processing method and device for trace gather record and storage medium

The embodiment of the invention provides a processing method and device for a trace gather record and a storage medium. The method includes the steps of according to a seismic wave velocity value, conducting dynamic correction on the trace gather record; calculating average amplitude, a similarity coefficient and an amplitude variance of a seismic trace record in the trace gather record after dynamic correction; according to the average amplitude, the similarity coefficient and the amplitude variance, working out a speed evaluation value, wherein the speed evaluation value is used for evaluating whether or not the seismic wave velocity value is a target dynamic correction speed of the trace gather record; changing the seismic wave velocity value to obtain the maximum speed evaluation value, wherein the seismic wave velocity value corresponding to the maximum speed evaluation value is the target dynamic correction speed of the trace gather record; according to the target dynamic correction speed, processing th
