| 英文摘要 | a set of experimental system to study hydrate dissociation in porous media is built and some experiments on hydrate dissociation by depressurization are carried out. a mathematical model is developed to simulate the hydrate dissociation by depressurization in hydrate-bearing porous media. the model can be used to analyze the effects of the flow of multiphase fluids, the kinetic process and endothermic process of hydrate dissociation, ice-water phase equilibrium, the variation of permeability, convection and conduction on the hydrate dissociation, and gas and water productions. the numerical results agree well with the experimental results, which validate our mathematical model. for a 3-d hydrate reservoir of class 3, the evolutions of pressure, temperature, and saturations are elucidated and the effects of some main parameters on gas and water rates are analyzed. numerical results show that gas can be produced effectively from hydrate reservoir in the first stage of depressurization. then, methods such as thermal stimulation or inhibitor injection should be considered due to the energy deficiency of formation energy. the numerical results for 3-d hydrate reservoir of class 1 show that the overlying gas hydrate zone can apparently enhance gas rate and prolong life span of gas reservoir. |
