摘 要：In order to enhance the accuracy and improved the resolution of the inversion result in gas hydrate exploration, this paper proposed a new inversion method. By introducing broadband constraint based simulated annealing impedance inversion, the new method allows for a more extensive search for the optimal solution and is more efficient than exhaustive enumeration in solving global optimization problems. Compared to other inversion solutions as constraint sparse spike inversion and model based inversion, the new method not only solved the global optimization problems, but also improved the resolution of the profiles and enhanced the inversion accuracy, which is helpful to the later interpretation.
