为了给水合物矿床高效采气提供解决方案，提出了微波辅助降压方法，并通过数值论证了其可行性。通过系统分析微波参数、物相组分和多孔介质性质的影响，发现微波加热可以为水合物解离提供及时、充足的能量，并且在高初始含水饱和度、高初始水合物饱和度、低比热容、高导热率、高孔隙率和低绝对渗透率的条件下，微波加热的能量效率可以相对较高。此外，对微波加热操作策略进行了评估和优化，以实现高能量效率和快速产气，这表明单循环连续加热模式在促进水合物解离方面具有最佳性能。与典型加热工况相比，优化后的单循环连续加热工况的能源效率和产气效率分别提高了20.73%和23.14%。本研究的结果有助于理解微波加热辅助降压诱导水合物分解的产气行为，可为评估和优化天然气水合物储层产气方法提供一些见解。
To provide solution for the high-efficient gas production from hydrate deposits, the microwave-assisted depressurization method is proposed, and its feasibility is numerically demonstrated. Through systematically analyzing the effects of microwave parameters, phase components, and porous media properties, we found that microwave heating can provide timely and sufficient energy for hydrate dissociation, and the energy efficiency of microwave heating can be relatively high in the condition of high initial water saturation, high initial hydrate saturation, low specific heat capacity, high thermal conductivity, high porosity, and low absolute permeability. In addition, the microwave heating operational strategy is evaluated and optimized to achieve the high energy efficiency and rapid gas production, which demonstrating that the one-cycle continuous heating mode has the best performance on promoting hydrate dissociation. Compared to the typical heating case, the energy efficiency and gas generation efficiency in the optimized one-cycle continuous heating case are enhanced by 20.73% and 23.14%, respectively. The findings of this study contribute to the understanding of gas production behavior of depressurization induced hydrate dissociation assisted by microwave heating, which can provide some insights for evaluating and optimizing the methodology for gas production from gas hydrate reservoirs.
