摘要

摘要: 天然气水合物是21世纪的新能源,对它的研究受到世界上许多国家的高度重视。青藏高原北部的羌塘盆地分布着一套我国唯一的海相侏罗系,油气资源潜力巨大,具有丰富的天然气来源和圈闭构造及永久冻土层。在详细论述天然气水合物形成条件、羌塘盆地构造及永久冻土特征的基础上,重点讨论了羌塘盆地天然气水合物地球物理特征的识别与预测。得出羌塘盆地地质条件较好,是寻找永久冻土带天然气水合物的有利地区的结论。并指出应尽快全方位的开展羌塘盆地及青藏高原其他地区天然气水合物的研究。

Abstract: The natural gas hydrates are one of the new energy resources of the 21st century, and many countries in the world pay great attention to investigation of the natural gas hydrates.In the north of Qinghai-Tibet plateau, there is an unique series of marine Jurassic sediments in Qiangtang basin which is the rich gas resources, traps and permafrost strata.The author discusses the forming conditions of natural gas hydrates, the tectonic unit division and the ever-permafrost characteristics.At the same time, the author placed emphasis on the geophysics recognition and prediction of natural gas hydrates.In accordance with the related analyses, the geological conditions are favorable for the natural gas hydrates exploration in permafrost zone.Taking long views, the investigation of gas hydrates in Qiangtang basin should be carried out as soon as possible.
