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。
The Qinghai-Xizang Plateau distributes the largest permafrost zone in China and develops well-developed Mesozoic-Cenozoic marine strata and marine and continental basins. This has created favorable conditions for the formation of gas hydrate deposits on the plateau. Based on the formation conditions of onshore gas hydrate, the paper discusses the possibility of formation of hydrate and the favorable distribution of mineral deposits from various aspects. It is considered that the Qinghai-Tibet Plateau is fully conditioned to form natural gas hydrate deposits. The most favorable distribution area is northern Tibet Outcrop area of the reservoir in the regional petroliferous basin. The study of hydrate deposits not only has resource significance, but also has potential environmental significance.
