Velocity Model Determining on Refracted Wave Data for Accounting of Variations in Upper Part of Seismic-Geological Section

Abstract

Summary An example of building a velocity model of the upper part of a seismic-geological section is given. Under the model constructing the times of the first arrivals of refracted waves are used. The created model is applied in the problem of static correction, but it can also be utilized for data migration. To improve the efficiency of the proposed technological solution, the methods of machine learning, ray seismic tomography and factors decomposition are used.
