Hydrostatic Properties of Hydrate-Bearing Sediments in Seafloor Multiphase Flow Zone
In this paper, a multiphase flow model of hydrate reservoir described the hydrate-water-gas-salt interaction in sediment pores in leakage environment had been established. The evolution of capillary pressure, porosity, relative and intrinsic permeability of sedimentary strata during hydrate forming had been estimated. According to this model the distribution of gas column in Shenhu area of north
