摘　　要：天然气水合物的资源潜力和开发前景十分广阔,是目前世界各国新能源研究的重点。对天然气水合物研究起步较早的美国、俄罗斯等国家已经进入天然气水合物气田的初步开发阶段,我国也已取得一定的研究成果。天然气水合物稳定带的形成需要一定的温度压力条件,人为地打破这种稳定的方法主要有热激发、降压、化学抑制剂等,文章对这几种开发方法的优缺点、应用现状进行了比较全面的比较,并根据目前仅有的开发实例对开采方式进行了探讨。如何解决天然气水合物的低成本开发技术问题,仍是最难克服的障碍。National gas hydrate is the focus of new energy sources explored worldwide. It has great potential resource and bright developing prospect,. The countries such as US and Russia, etc. who studied natural gas hydrate earlier, have entered the preliminary production stage of hydrate gas fields. China has also obtained some research fruits. Forming the stable belt of natural gas hydrate needs certain temperature and pressure conditions. The methods to crack the stability artificially include thermal activation, pressure releasing, chemical inhibitor, etc. The comprehensive comparison is made for the methods on the advantages and disadvantages. Meanwhile, according to the current status of application, with existing few real cases, the exploiting ways of natural gas hydrate are discussed. It is still the most problem how to exploit natural gas hydrate with low cost.
