The gas-lift method is expected as a method with the small running cost in order to recover the methane hydrate from the seabed. The methane gas injection makes the upward flow of the sea water, and it is necessary to establish the model able to estimate the sea water flow rate to the injected gas. Since the intended system is too large to conduct the experiment and multi-dimensional direct numerical simulation, this paper focuses on the calculation of the multi-phase flow in the one-dimension with the proper model equation for external forces. A drag force coefficient between gas and liquid is derived considering the liquid flow by the surrounding hydrostatic pressure. As a result, calculation with the proposed equation fairly agrees with the gas-lift experiment, compared with results with the other proposed model equations.
