摘要
青藏高原为我国中新生代海相沉积最发育的地区,存在着众多的中、新生代沉积盆地,油气勘探前景很大,尤其是羌塘和措勤盆地,但由于特殊地理条件的限制,区内地质研究程度很低,在海相中生界石油勘探方面,几乎为空白区。羌塘盆地为青藏高原面积最大、构造上较稳定的地区,基底埋深大,存在着隆、坳相间的构造格局,生油岩厚度大,生储盖组合条件较好。措勤盆地基底埋深较大,也存在较厚的生油岩。
Tibet Plateau is an area where Mesozoic marine deposits distribute extensively in China. On the Plateau there exists many Mesozoic and Cenozoic sedimentary basins. Qiangtang basin, the largest and the most stable tectonic unit on Tibet Plateau, has a tectonic pattern of large scale uplift alternating with depressions, its basement is buried deeply with thick source rocks. The source-reservoir-cap assemblage conditions are well developed. The North and South Qiangtang basin are well worth exploration. Having deeper basement and thicker source rocks, Cuoqin basin shows favorable exploration prospects.
