In solving wave equation in frequency domain,large-scale sparse matrix inverse is needed,if directly calculating the matrix inverse long time would be taken and large memory is needed,and further more it is difficult to solve 3D problem.But if utilizing the iterative algorithm which is being used nowadays,the convergence speed is very slow,or even not convergent for complicated medium model.In this paper bi-conjugate gradient stable algorithm is used to solve indefinite matrix for the outer layers,a attenuated wave equation operator in frequency domain is adopted as preconditioner for the bi-conjugate gradient stable algorithm,then multigrid algorithm is used to calculate the approximate inverse for the preconditioner for the inner layers.The method introduced in this paper raises the convergence speed for the iterative algorithm,instability problem for the iterative algorithm is also got solved,the numerical simulation results validates the effectiveness of the algorithm in this paper.
