摘　　要：塔里木盆地北部中、新生界油气藏形成条件较好,在库车凹陷具有形成大油气田的基本石油地质条件,在组合条件较好的其他地区,可形成中、小型油气田(藏)群.本区中、新生界油气田(藏)的分布具三种模式.区内已在震旦系至上第三系的九个层系内发现了规模不等的油气藏,其中80%集中在中、新生界内(主要分布在古隆起及斜坡带),表明塔里木盆地北部中、新生界有广阔的油气勘探远景.There are better oil and gas reservoir forming conditions in Mesozoic - Cenozoic in northern Tarim basin, Kuqa sag possesses basical petroleum geologic condition for forming giant oil and gas field, and medium - small type of oil and gas field group may form in the rest area with better assemblage conditions. There are three distribution models in Mesozoic - Cenozoic oil and gas reservoirs . Varieous scales of reservoirs were formed in nine series of Sinian - Neogene, among which 80% are in Mesozoic - Cenozoic (mainly distributed in paleo-uplift and slope belt) . These indicated that there are broad oil and gas prospecting potential in Mesozoic - Cenozoic in Tarim basin.
