摘　　要：微波加热技术作用速度快,设备简单,灵活性高,不对储层造成任何污染,适合于开采各类型天然气水合物资源。研究了微波开采天然气水合物气藏的机理,如加热作用、造缝作用和非热效应;总结了微波开采天然气水合物气藏的实验研究成果;指出微波加热开采天然气水合物气藏的3种方法:一是微波对由地面注入地层的水或盐水加热,二是微波通过直井对储层加热,使地层温度升高,三是微波通过多分支井对储层加热。Microwave heating technique takes effect quickly,uses simple equipment,is highly flexible and pollution-free to reservoir,and is suitable for recovering various natural gas hydrate resources.This paper focuses on the recovery mechanism of gas hydrate reservoirs,such as heating effect,fracture-making effect,and non-heat effect;summarizes the result of experimental research;and proposes three methods for recovering such reservoirs by microwave heating technique: firstly,water or salt water,which will be injected from the surface to reservoir formations,is heated by microwave,secondly,reservoir formations are heated directly by microwave through vertical well,and thirdly,reservoir formations are heated by microwave through multilateral wells.
