Method and device for determining anticline width by utilizing migration velocity scanning

The invention discloses a method and device for determining the anticline width by utilizing migration velocity scanning. The method comprises the steps of carrying out the preprocessing of the seismic data of a research region, and obtaining a horizontal superposition time profile; performing migration homing processing on the horizontal superposition time profile by adopting different migration speeds to obtain migration time sections corresponding to different migration speeds; comparing the anticline reflection feature information of the migration time profiles corresponding to different migration speeds with the anticline reflection feature information of the horizontal superposition time profile, and screening out a target migration time profile, wherein the anticline reflection migration of the target migration time profile does not exceed the preset migration range; and determining the anticline width of the underground structure of the research area according to the target migration time profile.
