建立了降压法开采水合物藏数学模型, 考虑了气-水-水合物-冰相多相渗流、水合物相变及分解动力学过程、冰-水相变、热传导、对流过程、渗透率变化等对于水合物分解的影响. 三维水合物藏模拟表明:在开采前期阶段, 可采用降压法, 但随着储层能量消耗, 产气速度下降很快, 需转变开采方式. 分析了一些主要参数, 如孔隙度、渗透率、饱和度、压力等对水合物开采的影响. |

A mathematical model is developed to simulate the hydrate dissociation by depressurization in hydrate-bearing porous medium. The model can be used to analyze the effects of the flow of multiphase fluids, the dissociation process of hydrate, the endothermic process of hydrate dissociation, ice-water phase equilibrium, the convection and conduction on the hydrate dissociation and gas and water production. The numerical results for 3-D hydrate reservoir showed that in the first stage of depressurization gas can be produced effectively from hydrate reservoir. Then, other methods should be considered to replace depressurization due to reservoir energy inefficiency. The effects of such physical variables as porosity, permeability, hydrate saturation, bottom pressure of production well on hydrate dissociation are analyzed. |
