摘要
本文利用碳同位素、常规有机地球化学、生物标志物、激光诱导荧光、包裹体特征等诸多方面论证了黄骅坳陷孔古3井奥陶系灰岩中所产原油为奥陶系自生自储的，而与C－P系关系疏远。这一认识对评价华北地区下古生界海相碳酸盐岩的含油气远景具有重要的意义。
This paper demonstrates that oil generated in Ordovician carbonate rocks of Konggu-3 well is of the generating and self-reserving type in terms of carbon isotope, conventional organic geochemistry,biomarkers, laser induced fluorescence spectrum, and inclusion characteristics. The oil is derived greatly from the C-P system. The result is of important significance in evaluating oil-gas prospects of the Lower Palaeozoic marine carbonate rocks in North China.
