| 英文摘要 | The low efficiency and unstable gas production of hydrate exploitation have become the difficulties restricting the commercial development of combustible ice. In this work, based on the existing geological conditions, this paper establishes a low-permeability hydrate heterogeneous reservoir model to analyze the effects of hot water injection on well and reservoir. The results show that the greater the wasted heat from the produced water and some injected water migrating to the gaseous hydrocarbon layer and the underlying at the middle and late stage of hydrate production as the hot water injection rate. Moreover, the gas and water production will suddenly appear surge phenomenon during the hydrate production due to the disappearance of the water lock effect affected by thermal-hydraulic-chemical multi-field coupling, which depends on the hot fluid properties. Therefore, the new technology of slow hot water injection after depressurization or different injection rates at different stages in the injection well is proposed in this paper. And it is also necessary to optimize the vertical position of the injection well or add a thin layer with low permeability at the bottom of the gaseous hydrocarbon layer. Finally, the hot water injection temperature should be controlled above 50 degrees C. |
