摘要
伦坡拉盆地是西藏高原唐古拉山南侧的一个新生代陆相沉积盆地,从第三纪牛堡组和丁青湖组的地层特征、古地貌演化、沉积层序及体系域类型的归属、沉积相类型及其展布特征等几个方面描述了沉积体系域的基本特点.指出了伦坡拉盆地是一个残留的变形盆地,其沉积古地貌特征与现今盆地构造格局明显不同,并控制了沉积相的类型及其展布.最后对有利油气聚集的相带和区块进行了预测分析.
Lunpola basin is a Cenozoic deposition basin of continental fades,located in the south of Tanggula Mountain in Xizang(Tibet)Plateau.The basic characteristics of deposition systems are discussed from the features of stratigraphy evolution of paleo-geomorphology,classification of deposition sequence and systems tract,types of deposition facies and distribution of paleogene Niubao Formation and Dingqinghu Formation.It is pointed out that the basin is a deformed one and that its paleo-geomorphic feature is obviously different from present-day tectonic framework in the basin.It controls the types of deposition facies and distribution of facies zones.Finally,favourable facies zones and areas are predicted for oil and gas accumulation.
