Abstract:

In 1984,a high-rate oil flow has been tested from the Paleozoic marine carbonates in Shacan 2 well,northern Tarim basin, which means a new prospect has been opened up in the Paleozoic petroleum exploration in the basin.Through a 20-year sustained efforts,18 fields,including the large Tahe oilfield and Hetianhe gasfield,have been discovered in the Paleozoic.It shows that the Paleozoic in Tarim basin has abundant oil and gas resources,favorable reservoiring conditions,and suitable geologic conditions for the formation of large-giant oil and gas fields,thus its exploration potential is very large.

Key words: Tarim basin, Paleozoic, petroleum exploration, potential analysis
