| 摘 要： | 通过对墨西哥湾岸盆地大量原油样品的抽样调查,其地球化学特征表明,原油的成因类型主要有5组,即①上侏罗统牛津阶海相泥灰岩;②上侏罗统牛津阶海相碳酸盐岩;③上侏罗统提塘阶海相泥灰岩;④白垩系海相碳酸盐岩—蒸发岩;⑤第三系海相三角洲碎屑岩。每一组都与特定的烃源岩有关。烃源岩为多源输入,多相(石油—天然气)变化,已达到成熟,并经历了后期填充蚀变过程。

| Abstract: | Geochemical and isotopic characteristics of a wide selection of the produced oils in the petroleum subprovinces from the Mexican Gulf Coast Basin have revealed five major genetic patterns corresponding to five types of lithofacies namely:(1)Oxfordian marine marlite,(2)Oxfordian marine carbonate-dominated,(3)Tithonian marine marlite,(4)Cretaceous marine carbonate-evaporitic,and(5)Tertiary marine deltaic clastics.Each of them is related to specific hydrocarbon source rocks,which are of multi-source input and ... |
