摘　　要：青藏高原在构造位置上处于特提斯构造域东段,是我国海相三叠系—新近系分布面积最大、最集中的地区。其上发育中-新生代各类沉积残留盆地,其中陆相盆地20个,海相盆地7个。通过与特提斯构造域石油地质条件的初步对比,认识到青藏高原虽作为其东段的主体,两者在构造演化上密切相关,但在含油气盆地的特征上存在较大的差别。结合新一轮油气资源评价结果,认为羌塘盆地为该区首选勘探目标,盆地中部为最有利的油气远景区,并从中筛选出3个重点区块作为近期勘探目标:托纳木—笙根区块、隆鄂尼—昂达尔错区块及土门达卓玛区块,同时指出措勤盆地勘探前景次之。The Qinghai-Tibet Plateau is located in the east of Tertiary marine rock strata. It possesses various types of depositional-residual basin ,including 20 continental basins and 7 marine basins. The comparison of petroleum geological conditions on these basins and Tethys domain indicates that the plateau is similar to Tethys domain in their structural evolution, but they are different in their characters of petroliferous basin. On the basis of results of newly hydrocarbon resources assessment, this paper suggests that the Qiangtang Basin should be a major exploration target, whose center is the most favorable prospect area. As Cuoqin Basin is less potential , the paper proposes 3 main blocks： Tuolamu-Shenggen block ,Nongeni-Angdaercuo block and Tuomen-Dazuoma block as prospecting objects in the near future.
