Abstract: T50 surface, one of thirteen unconformity surfaces in Tarim basin plays a very important role in formation of oil and gas reservoir in Tarim basin. Reservoir may form when oil and gas iiiigrated along upper and lower carried beds of T50 surface and encountered better trap. Combination of T50 surface and fault constitutes Zeta-type, “丰”-type. and chess-board type oil/gas migration.

Key words: Tarim Basin, Unconformity surface, Oil and gas migration, Migration mode
