STUDY ON NATURAL GAS PRODUCTION FROM HYDRATES
A one-dimensional physical model of natural gas production from hydrate dissociation in a reservoir by depressurization is studied in this paper. According to the principles of solid hydrate decomposition in stratum and flow of natural gas in porous medium, the pressure governing equations for both gas zone and hydrate zone are set up basing on the physical production model. Through calculation, for different reservoir parameters, the distribution characters of pressure are analyzed. The decline trend of natural gas production rate with time is also studied.
