Abstract: Natural gas hydrate is honored as the most commercially valuable strategic resources in 21st century. It is also considered to be a highly efficient gas reservoir for its special cage crystal structure with great gas storage capacity. This provides a new way to gas storage and transportation technology. Domestic and abroad researches concerning about gas hydrate formation in surfactant were summarized. The effects of surfactant on the hydrate were analyzed. The effects of various types surfactant namely sodium dodecylsulfate(SDS), sodium dodecyl benzene sulfate(SDBS) and cetyltrimethylammonium bromide(CTAB) were analyzed. The dynamics mechanism on gas hydrate was expounded. Composite surfactants are believed to be effective on overcoming the existing inadequacy. The future research direction will include establishment of the hydrate kinetic model containing surfactant parameters.

Key words: gas hydrate, promoting formation, surfactant, storage and transportation
