High resolution radon transform operator of the borehole seismic wave field
井孔高分辨率Radon变换算子研究

According to apparent linear wavefield of crosswell and 3D VSP, we study the application of high resolution Radon transform to crosswell layout. In view of crosswell and 3D VSP layout, we use high resolution Radon transform based on Cauchy distribution to perform Radon transform for hole data. In this process, we study discrete dip overlay operator, improve damping factor that affects Radon energy convergence in order to let Radon energy converge, 6 resolve leggy in Radon data, and decouple smoothing effect among each energy group, we use Cauchy distribution to regularize data, let energy focus on one point, and improve Radon resolution. All these work well in wavefield separation. Finally, by inversion results and model trial, we verify the feasibility and stability of this method.
