Currently manifest problems of gas hydrate formation, complicating technology exploration, production, transportation, storage and processing of gas. Natural gases in certain thermodynamic conditions come into connection with the water and form crystals of gas hydrates accumulated in the various piping systems, wells, and crafts. Terms of combat gas hydrates are complex, cost methods of prevention and elimination of gas hydrates in the systems of exploration, production and transportation of raw materials are rising. First gas hydrate was obtained by a member of the Royal Society of England (later its president ) H. Davy in 1811 in the 20s study hydrates engaged renowned physicist Michael Faraday , who in 1823 first defined the composition of chlorine hydrate. During the next century were obtained equilibrium curves of some gas hydrates studied their compositions, but the properties of hydrates have remained virtually unexplored, especially the influence of gas hydrates on the surrounding sedimentary rocks and formation waters. Until recently, studies of gas hydrate were purely academic. Properties of hydrates were examined as to find a useful application in the industry. In the 60s of the last century to the study of gas hydrate involved modern instrumental methods of research, there are serious theoretical generalizations, which resulted in the study the main structural features of the various hydrates, studied some of their properties.
