FORMATION AND CONTROLLING FACTORS OF GAS HYDRATES

Gas hydrates is a kind of crystal of natural gases that are caged in water.They mainly exist in polar region and in seafloor where temperature are very low and pressure are very high,because its formation and existence need special temperature and pressure.All geological factors that could affect the temperature and pressure are the controlling factors of their formatiom and existence.In accordance with ana lysis of controlling factors,a formation model of gas hydrates was proposed,with that may provide an useful clue for exploration of this kind of resource.
