英文摘要 | Waveform inversion is a kind of method to reveal the underground structure and lithology information through minimizing the residual error between predicted wavefield and true seismic record using full-wavefield information. In this paper, we briefly state the principle of conventional Quasi-Newton algorithm, and then exploit a new modified Quasi-Newton equation to modify the conventional Davidon-Fletcher-Powell (DFP) and Broyden-Fletcher-Goldfarb-Shanno (BFGS) algorithm. Different from past Quasi-Newton methods, this modified BFGS algorithm considers gradient value, model information and objective function value together to approximate the inverse matrix of Hessian matrix; moreover it almost does not increase the calculation amount for each iteration. Finally, numerical experiment shows that compared with conventional Quasi-Newton method, modified BFGS algorithm can not only preserve the inversion accuracy, but significantly improve calculation efficiency. |
