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3000m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。Tula basin is located among the southwestern Qaidam basin,the southeastern Tarim basin and the north of Kekexili mountain ranges,with above sea level of3000meters,being sparsely populated and very low mature explo-ration.Through field geologic survey and preliminary composite researches in petroleum geology,its formation mecha-nism 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.
