    摘要:In this work, different saturated methane hydrates were formed by controlling the methane gas filling pressure on the three-dimensional experimental systems. The hydrates were dissociated using by depressurization and combination method, respectively. The results indicated that, as the saturation enhancing, the gas production was enlarged, however, the gas production rate became extremely volatile, and the decomposition cycle increased. Furthermore, compared with single depressurization, the combination method has the high gas production rate and efficiency, and the short decomposition cycle. So the combination method is worthy for further study of the gas hydrate exploitation.
