Method for increasing seismic imaging resolution ratio

The invention discloses a method for increasing a seismic imaging resolution ratio and is applied to reflection seismic data processing in seismic exploration . The method includes that by performing frequency-dependent amplitude recovery and frequency dispersion correction on migration stack data volume, the resolution ratio of imaging is increased integrally, and the imaging resolution ratios of middle and deep structures are enabled to be close to the imaging resolution ratio of a shallow structure; amplitude recovery and frequency dispersion correction are performed based on a viscoelastic theory, but a nonuniform Q value field does not need to be provided in advance; viscous absorption of seismic waves is described by introducing an equivalence Q value, and the nonuniform equivalent Q value field needed for calculation is acquired by establishing a single numerical indicator and by utilizing parameter scanning. Compared with methods like unsteady-state deconvolution, the method has the advantages that high-frequency information is restored while frequency dispersion correction is completed; a stable control algorithm is introduced, so that stability of calculation is guaranteed. By the method, breaking of the middle and deep structures and stratum deposition forms can be indicated better; and the method has important application value for oil-gas and mineral resource exploration.
