VTI medium dual-parameter result analyzing method based on interactive pickup process on same interface

The present invention provides a VTI medium dual-parameter result analyzing method based on an interactive pickup process on the same interface and belongs to the field of the processing technique for exploration and seismic data. The method comprises the steps of (1) analyzing a stacking velocity based on the principle of velocity spectrum to pick up a stacking velocity v at the time t, on the basis of seismic data detected at a short offset; (2) picking up Eta e based on the same-interface and dual-parameter analysis as the key design; (3) calculating the Eta i of each layer; (4) figuring out Delta through the combined calculation of logging and seismic data; 5) calculating Epsilon. According to the technical scheme of the invention, through stacking up velocity parameters and Eta, the Thomsen parameter Epsilon and Delta can be figured out based on mathematical physical equations. Therefore, model parameters are provided for the migration imaging process of the VTI medium, so that the seismic imaging accuracy is improved.
