This paper summarized the advances in experimental investigations on seepage characteristics of hydrate-bearing sediments and the shortcomings of current experiments. Both the fundamental principle and the application status of the transient pulse method applied for permeability measurements were introduced, and the feasibility of the method for hydrate-bearing sediments was discussed. It is shown that the three shortcomings of the existing experimental measurement methods including hard to keep steady flow, long time consuming, and formation/dissociation of hydrate during measurement, can be overcome by using transient pulse method. The transient pulse method is of great feasibility for hydrate-bearing sediments, particularly in the South China Sea. Seepage characteristics of hydrate-bearing sediments during hydrate formation and dissociation should be experimentally studied in the future.
