Definition of three-dimensional inhomogeneous layered velocity model from reflection seismic data

PDFRead

Abstract. The given paper deals with the problem of 3-D velocity layered model definition from reflection seismic data. It gives the description of basic methods for the named problem, gives the compare analysis, discusses advantages and disadvantages of these methods. It demonstrates a new iteration algorithm for the determination of the medium model with inhomogeneous curve-linear layers which does not require the wave front curvature. It is evident from the work that in order to define velocities in the inhomogeneous strata one has to solve an inverse problem for the model with locally-homogeneous layers. It demonstrates the optimization algorithm that does not require multiple solution of the direct problem and reduces time-consumption significantly.
