| 摘 要： | 通过对渤南洼陷沙河街组部分烃源岩、原油、含油砂岩抽提物中的饱和烃化合物进行GC和GC—MS分析，研究饱和烃色谱和生物标志物特征，讨论了沙三段原油的来源问题。结果表明，沙四段和沙三段烃源岩均可分为两类，沙三段原油可以分为差别明显的三类。油源对比表明，第一类原油来自沙四上亚段膏岩层段的暗色泥岩夹层，第二类原油来自沙四段膏岩层下部的泥岩层段，第三类原油来自沙三段时期淡水-微咸水还原环境下的暗色泥岩。

| Abstract: | Through the analysis of GC and GC-MS for saturated hydrocarbon compound of extraction from partial hydrocarbon source rock,crude oil and oil sandstone of Shahejie Formation,this paper studies the color spectrum of saturated hydrocarbon and biomarker features,and discusses oil origin of Sha 3 Member.Result shows that hydrocarbon source rock of Sha 4 Member and Sha 3Member can be divided into 2 types and oil of Sha 3 Member into 3 types with obvious differences.Oil source correlation indicates the first type of crude oil origins from dark mudstone interbed of Sha 4 upper sub-member gyprock intervals,the second from mudstone intervals in the lower gyprock interval of Sha 4 Member and the third from dark mudstone in the reducing environment of fresh water-brackish water in the process of Sha 3 Member. |
