摘要： 吐拉盆地是位于柴达木盆地西南、塔里木盆地东南、可可西里山脉以北的一个盆地,该盆地海拔3 000 m以上,人烟稀少,勘探程度很低。经过野外地质调查和初步的石油地质综合研究工作,初步确认了盆地的形成机制,划分了构造单元,认为盆地内中、下侏罗统的泥岩是重要的烃源岩,油气勘探的有利领域在盆地的北部和中部,特别是在吐拉牧场凹陷中,有可能发现侏罗系自生自储式的油气田。

Abstract: Tula basin is located among the southwestern Qaidam basin, the southeastern Tarim basin and the north of Kekexili mountain ranges, with above sea level of 3000 meters, being sparsely populated and very low mature exploration. Through field geologic survey and preliminary composite researches in petroleum geology, its formation mechanism has been confirmed, its structural units has been classified initially. The results show that the mudstone of Middle-Lower Jurassic in Tula basin is a major source rock; the favorable domains for petroleum prospecting are in the north and middle areas of the basin; particularly in Tula pasture sag,it is possible to find out oil and gas fields with both source and reservoir in Jurassic.

Key words: Tula basin, Qingzang plateau, Jurassic, source rock, exploration
