| 摘要: |
| 青藏高原分布着中国规模最大的多年冻土带,发育有良好的中、新生代海相地层及海相、陆相盆地,为高原天然气水合物矿藏的形成创造了有利条件。本文根据陆上天然气水合物的形成条件,从多方面讨论了水合物形成的可能性及其矿藏有利的分布位置,认为青藏高原完全有条件形成天然气水合物矿藏,最有利的分布区是藏北地区含油气盆地储集层的露头区。对水合物矿藏的研究不但具有资源意义,而且还有潜在的环境意义。 |

| Abstract: |
| The Qinghai-Tibet Plateau has harsh natural conditions and on it the largest permafrost region in China is distributed and Meso-Cenozoic marine strata and marine and terrestrial basins are well devel-oped,which provides advantageous conditions for forming natural gas hydrate accumulations on the plateau.Based on the formation conditions of terrestrial natural gas hydrates,the paper discusses from several aspects the possibility of forming hydrates and the favorable locations where natural gas hydrate accumulations are most likely to occur.Finally the authors indicate that the Qinghai-Tibet Plateau has good conditions for forming natural gas hydrate accumulations and that the most favorable area is the outcrop area of accumula-tions of petroleum-bearing basins in northern Tibet.The study of natural gas hydrate accumulations has not only significance of resources but also great environmental significance. |
