摘　　要：为了弥补降压法开采后期储层结冰、水合物二次生成等方面的不足,运用微波加热技术向储层进行能量补充。选用漏泄同轴天线作为微波加热装置,根据装置结构设计天然气水合物储层微波加热工艺方案,并且建立水合物储层微波加热仿真模型,通过试验验证仿真模型的准确性,并分析储层性质对微波加热后储层温度的影响规律。结果表明:储层微波加热工艺方案能够有效提升储层温度,储层初始温度为2℃,微波加热后储层最高温度为26.22℃,平均温度为5.19℃;储层温度随着损耗因子的增大而增大,随着介电常数的增大而减小;随着储层密度和比定压热容的增大,储层升温效果变差;随着储层导热系数的增大,储层温度分布更加均匀。Microwave heating can be used to supplement energy to gas hydrate reservoir in order to prevent icing and secondary hydrate formation in the late stage of depressurization for gas production.In this study,a leaky coaxial antenna was selected as the microwave heating device,and a microwave heating scheme of gas hydrate reservoir was designed according to the structure of the device.The effectiveness of the microwave heating was verified by experiments,and the influence of reservoir properties on reservoir temperature after heating was analyzed.The results show that the microwave heating technique can effectively increase the reservoir temperature.When the initial temperature of the reservoir is 2℃,the maximum temperature of the reservoir after the heating can reach to 26.22℃,and the average temperature is of 5.19℃.The reservoir temperature increases with the increase of loss factor and decreases with the increase of dielectric constant.With the increase of reservoir density and specific heat capacity,the heating effect is reduced.With the increase of reservoir thermal conductivity,the distribution of the reservoir temperature becomes more uniform.
