摘要

Method for su00ecsmica migration in a medium with anisotropic operators explu00eccitos restricted. The present invention relates to operators of the extrapolation of depth limited explicit that are constructed with the lengths of the operator variables depending on the angles of maximum phase, the condition of the accuracy of parameters of anisotropy and the number of wave.Tables of operator are constructed using the operator extrapolation depth having the shortest length of explicit operator satisfying the condition of accuracy on the angle of maximum phase for each of the plurality of parameters of anisotropy and a plurality of number. S wave.A depth migration is carried out using the extrapolation operator of depth limited explicit in a depth which has a length of operator less from tables of the operator for the number of wave.
