摘　　要：青藏高原的含油气盆地是属多个板块构造旋回、长期发展的叠合型含油气盆地;具有生物成因和非生物成因两大油气源叠合、富集的特征,是中国和全球特殊的高原型含油气盆地。其特殊性与中新生代发生的陆块间和大陆间的碰撞活动有关,属于强烈碰撞型含油气区。其特点是地壳厚度大、地面隆升幅度高、自然地理环境差,是我国目前勘探程度较低的地区,但与近年来兴起的热点地区——北冰洋和南极洲相比,又有它有利的一面,是我国油气资源持续发展的后备战略地区。The petroliferous basin in Qinghai-Tibet plateau is a superimposed basin with multi-plate tectonic cycles, long-period development, organic-inorganic genetic sources and peculiar plateau type in China and even in the world. Its particularity is related to inter-landblock and intercontinental collision activities of Mesozoic and Cenozoic, so it also belongs to an intensive collision-type petroliferous province. The study shows that it is characterized by the fact that the thickness of the crust is big, the extent of the surface uplift is high and the natural geographical environment is poor, being the lower exploration-extent area in China at present. However, compared with the Arctic Ocean and Antarctica that are the hot-spot areas on the rise in recent years, this petroliferous province could be strategically one of explorative areas for replacement of oil resources in China.
