An embodiment of the invention discloses a gather record processing method, a device thereof and a computer storage medium, wherein the gather record processing method comprises the steps of receivingat least one gather record in an industrial area; calculating an industrial area surface speed according to the shot-geophone distance and the initial arriving time of a seismic trace in the gather record; receiving a first gather record in the industrial area; calculating a correction time difference according to the shot point of the generated first gather record, the elevation of the seismic trace and the industrial area surface layer speed, wherein the elevation is the height of the shot point and the seismic trace relative to a reference plane; and correcting the first arrival time of the seismic trace in the first gather record according to the correction time difference. The gather record processing method according to the invention has advantages of eliminating influence of landform fluctuation and transverse speed change, and quickly improving complicated land surface refraction layer identification degree.
