| 英文摘要 | Natural gas hydrate is a fresh kind of unconventional energy with abundant reserves. How to attain high-efficiency extraction of the methane gas from gas hydrate has become a critical challenge to commercial utilization. Planning hydrate reservoir exploitation depends heavily upon heat transfer, including heat convection and heat conduction. In order to reveal the enhancing mechanism of heat transfer on the gas production of the natural gas hydrate, the hydrate decomposition performance in a high-pressure reactor has been investigated with a multiple well system by using thermally assisted depressurization methods including warm water flooding and electric heating. Results show that the energy attained by the plain depressurization method is restricted by the limited heat supply in the surrounding environment. The strong thermal convection in warm water flooding plays a dominant role in the rapid dissolution of hydrates during its flowing from the injection well to the production well, while electric heating hardly makes a contribution in the initial phases due to the delayed effect. However, the heat conduction effect becomes stronger when the temperature of the deposit increases to a higher level. Moreover, the water flooding regime without additional heat occupies an unexpected advantage in energy recovery, which promotes heat transfer in the combined method to the undissociated area of hydrate. In the aspect of comprehensive energy efficiency, heat utilization, and time cost, it is considered that the combined method of depressurization with electric heating and water flooding has more advantages for the future commercial production test. |
