The theory and method of quality factor (Q) estimation using P-wave first break in three-component vertical-seis- mic-profile (VSP) seismic data, stabilized inverse Q-filtering method were given and a processing flow for improving surface seismic data resolution combined with VSP seismic data was proposed. The elastic parameters can be derived from three-com- ponent VSP seismic dataset, such as velocity ratio of P-and S-wave, Poisson’s ratio and volume modulus. These parameters can be used to correct the Q model estimated from VSP seismic data. The results show that the methods and technique process are feasible. It can enhance the seismic resolution without effects on the seismic signal-to-noise ratio. Compared with the stacked VSP seismic trace to the seismic sections before and after inverse Q filtering, the seismic data with high resolution agrees well with the VSP results.
