摘要： T50面是塔里木盆地中13个不整合面中的一个,它对塔里木盆地油气藏的形成起着重要作用。油气沿T50面上下输导层运移,遇有良好的圈闭即可形成油气藏。T50与断层配合构成了“歹”字型、“丰”字型和“井”字型等3种主要油气成藏运移模式。

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
