摘要

The Seismic pre-stack inversion technology can make full use of pre-stack information to accurately predict various parameters of reservoir media, which greatly enriches the means of describing reservoirs and is widely used in oil and gas exploration and development. However, seismic inversion is a typical ill-posed problem. Using regularization can overcome this problem and reduce the ill-posedness of the inversion problem. In this paper, a prestack three-parameter inversion method based on ATpV regularization is proposed. This method introduces ATpV regularization into prestack inversion, which effectively solves the ill-posed problem of inversion. The experimental results show that this method has the advantages of small inversion error and good sparsity.
