| 英文摘要 | In this paper, we introduce the Viterbi algorithm and apply it to auto pick the stack velocity. Here, the Viterbi algorithm makes the rule to integral the max velocity spectrum, "energy group", forward and to get the optimal solution in recursion backward. The veracity of the solution has relation to the objective function, namely, the resolution of velocity spectrum. Therefore, we introduce a method of fairing for image processing to smooth the surface of velocity spectrum, to improve the resolution of velocity spectrum, finally, to provide a new way to obtain a solution of high accuracy. The results showed that it is not only helpful to improve precision of velocity picked, but also to realize auto-picking velocity by the Viterbi algorithm combined with surface fairing. Therefore, it is not only helpful to improve the efficiency of the conventional seismic data processing, but also rapid to provide the initial velocity for pre-stack depth migration. |
