Abstarct: Seismic images requires detailed seismic velocity model, but due to high speed contrast in areas with complex structure, the seismic reflector is difficult. For this reason, generally within the ground wave propagation velocity modeling process is very complex. A fast modeling techniques such data, use of computed tomography or lattice laxyer is. Tomography is a method to evaluate compliance with the time taken to achieve quality seismic data in elderly higher screw speed model. This method to replicate the update, with high accuracy. Another advantage of this method is the use of the structure with heterogeneity. Using seismic tomography data, particularly in heterogeneous areas, increased resolution between laxyers and reduce the depth errors. In this study, we improved the time taken using a network tomographic method baxsed on laxyered structures has been uneven. That is, by using network tomography baxsed laxyer tomography deep profile of the resulting stack has been optimized, which has many advantages compared with other methods of depth to update and improve the quality of the resulting profile been sent.
