Abstract: The TaYlm BaSln WaS dlVlded Into 4 ISOlated SUb-baSlnS by the 5haya Upllft In the nOYth andthe central Tarim denudation area in the center and the west during Triassic.In the northern and centralTarim Basin,the Triassic strata are preserved the most widely.Hydrocarbon in the Tahe Oil Field isfound mainly in Triassic,vertically divided into 3 reservoir layers:the bottom,the middle and the top.Sandbodies in the top layer generate better and distribute more widely than those in the middle and bot-tom layers,and advance to the south.Self-generated and self-accum Mated reservoirs might generateduring the early Triassic in the central Tarim Basin;hence the lower Triassic in the Central Tarim LowUplift has good potential for exploration.
