Based on a set of high-pressure visual experiment device built for the investigation of the natural gas hydrates crystallization and growth on the suspended gas bubble surface, the influence factors such as pressure, temperature, water quality were analyzed and discussed. The results showed that the higher pressure or the lower temperature resulted in the less induction time and growth time, which led to surface changing from rough to smooth. The surface of hydrate film in distilled water is smoother and tidier than that in pure water. Under the same experimental conditions, the hydrate film in distilled water grew faster than that in pure water.
