摘要: 综合研究了轮南地区原油的地球化学特征,结合构造发育史、烃源岩演化史和油气分布特征,认为轮南地区原油主要来源于寒武系–下奥陶统烃源岩,并指出塔里木盆地的油气勘探应该主要集中到以寒武系– 下奥陶统为主要烃源岩的战略目标上来,在轮南地区寄希望于中– 上奥陶统为烃源岩来寻找大油田是不可思议的,必将引起对勘探的误导。

Abstract: The geochemistry of Lunnan crude is comprehensively studied.This paper presents that Lunnan crude primarily originates from the Cambrian-Lower Ordovician source rocks, combined with the structural development history, the source rock evolution history and oil gas distribution characteristics.So the Cambrian-Lower Ordovician strata should be taken as major source rocks for petroleum exploration in Tarim basin instead of pinning our hope on search for giant oilfield in Middle-Upper Ordovician strata as major source rocks in order to avoid the existed misdirection.

Key words: Tarim basin, Lunnan oilfield, geochemistry, source correlation, petroleum potential
