气水合物是天然气和水分子组成的固体结晶物质,是水和以甲烷等为主的有机气体构成的可燃性物质,主要存在于极地和海底温度很低的海域.气水合物的形成和存在有其严格的温度压力条件,一切能影响到气水合物的压力和温度的地质因素就是控制气水合物形成和存在的因素.该文利用国内外已有资料总结归纳气水合物的成藏模式,并通过分析指出了气水合物存在的控制因素,希望它能对加速发现气水合物提供一些有益的线索.

Gas hydrates is a kind of crystal of natural gases that are caged in water.They mainly exist in polar region and in seafloor where temperature are very low and pressure are very high,because its formation and existence need special temperature and pressure.All geological factors that could affect the temperature and pressure are the controlling factors of their formatiom and existence.In accordance with ana lysis of controlling factors,a formation model of gas hydrates was proposed,with that may provide an useful clue for exploration of this kind of resource.
