Abstract: Research advances in promotion technology of gas hydrate formation process are comprehensively reviewed, the status of reinforcing methods is summarized, and their relative merits are analyzed. The results show that the existing research of reinforcing methods was confined in hydration reaction process itself, and these methods such as stirring, bubbling and adding chemical additives could promote the formation process and shorten the induction time of hydrate formation. However, the formation process of hydrate is a complicated hydration reaction process with heat and mass transfer. The existing research has failed to accurately reveal the process mechanism. It is necessary to establish growth model of hydrate by putting the influential factors such as temperature, pressure, size of the object, state of water and degree of agitation into consideration, and accurately reveal the promoting mechanism of hydrate formation process. Finally, existing problems and future research direction in promotion of gas hydrate formation process are also pointed out.
