Abstract: Simulation experiment study on the natural gas hydrate is very important. This paper firstly ana-lyzed the simulation experimental apparatus for natural gas hydrate at home and abroad and relative studies. Secondly, the components of experiment systems for gas hydrate and the technological gap between the de-veloped countries and China are described. Finally, according to the induction of features and trends of ex-perimental apparatus for natural gas hydrate at home and abroad, the paper proposed some suggestions which could enhance the integrated experimental study on gas hydrate in China.
