Abstract: An inversion method for seismic wavelets and reflection coefficients, in which it is assumed that the seismic wavelets have compact support, and are smooth, and the reflection coefficients are relatively sparse. Corresponding optimization problems for the inversion of seismic wavelet and reflection coefficient sequence are constructed. By using alternating iteration, the joint inversion problem of the seismic wavelets and the reflection coefficients, which is based on compact smoothness and relative sparsity, is divided into a seismic wavelet inversion subproblem and a reflection coefficient inversion subproblem. The two subproblems are solved using a proximal algorithm. A system for implementing the inversion method is also provided herein.

Abstract: Disclosed herein is a method of stripping a strong reflection layer based on deep learning. The method establishes a direct mapping relationship between a strong reflection signal and seismic data of a target work area through a nonlinear mapping function of the deep neural network, and strips a strong reflection layer after the strong layer is accurately predicted. A mapping relationship between the seismic data containing the strong reflection layer and an event of the strong reflection layer is directedly found through training parameters. In addition, this method does not require an empirical parameter adjustment, and only needs to prepare a training sample that meets the actual conditions of the target work area according to the described rules.
