Description
technical field [0001] The invention relates to the application field of natural gas hydrate, in particular to a system for studying the phase transition law of gas hydrate and its application method. Background technique [0002] Natural gas hydrate is an important alternative clean energy. It has the characteristics of high energy density, huge reserves, and low pollution after combustion. In the trench. Compared with conventional fossil energy, the stable occurrence of natural gas hydrate requires low temperature and high pressure conditions, and it will undergo phase transition between gas-liquid-solid in the limited pore space, making the corresponding multiphase flow more complicated In severe cases, it will cause disasters including wellbore blockage, blowout and kick, stratum collapse, and submarine landslides. Therefore, it is necessary to have an in-depth understanding of the phase equilibrium and multiphase flow of hydrates under different working conditions. ...
