Multiphase fluid flow,Conductive and convective heat transfer,intrinsic kinetics of hydrate decomposition,and deformation of sediments are four basic physical-chemical processes in the exploitation of gas hydrate.The multiphase fluid flow leads to the pore pressure dissipation and the deformation of hydrate bearing sediments(HBS) accompanied by the convective and conductive heat transfer,and then the hydrate recovery.The absolute permeability of HBS is one of the key controlling factors.The advances in the …
