Abstract: The paper a theoretical model and migration of methane bubbles in the hydrate formation conditions in the upward flow of water in a vertical channel is suggested and built. We obtain critical values of mass flow rates of gas and water, providing the necessary conditions for the full transition to the reactor, the gas in the gas hydrate. It is found out that at migration of gas bubbles in the reactor, two possible modes of the process of hydrate depending on the initial mass flow rate of water: gas bubbles or completely converted into hydrated state as separate inclusions or partially, forming bubbles with a hydrated shell. Analysis of influence of size of gas bubbles on the process of hydrate formation.

Keywords: gas hydrates, crack, canal, bubbles.
