Abstract: Commercial oil/gas flows have been obtained in ten layer series in Tabei uplift of Tarim basin, and four categories, thirteen types of reservoirs have been found.Based on source rock, trap, reservoir-cap assemblage and preservation conditions, formation and evolution of reservoirs were analysed.It is considered that the reservoirs in Tabei uplift are characterized by multiple types, multiple layer series, mutiple reservoir-formed stages, deep burial, small scales and distribution along faults and unconformable surface.Hydrocarbon accumulation in Tabei uplift belt was controlled by regional structure framework, and divided into a marine petroliferous system in south and a continental petroliferous system in north.

Key words: Tarim basin, Tabei uplift, Reservoir formation, Reservoir type, Reservoir distribution, Control, Condition
