天然气水合物开发前景和环境问题

THE DEVEOPMENT PERAPECTIVE AND ENVIRONMENTAL PROBLEMS OF NATURAL GAS HYDRATES

通过对国内外最新资料的分析指出,与上个世纪估算的全世界天然气水合物总资源量相比,最新估算的天然气水合物资源量明显减少,已经不是煤、石油和天然气总资源量的2倍;但是,仍然相当于目前全世界的油气资源总量,又因其分布广、资源量巨大、能量密度高而极具开发前景。认为开发天然气水合物会引发一系列负面环境效应,如温室效应、海底滑坡和海洋生态平衡的破坏等。

Scientists always pay attention to natural gas hydrates since it was discovered. By analyzing and comparing the dates of all over the world, the paper has drawed the conclusion that the amount of natural gas hydrates has deduced, it was considered the twice as the resource extend of coal, oil and gas in the last century, but now it is only the same as the resource extent of oil and gas. The natureal gas hydrates has brought development perspective with its broadly dispersed, greatly deposits and high energy density. But it may cause a series of environmental effects, such as Greenhouse effect, submarine landslide and destroy of ecological balance of sea and so on.
