采用ＧＣ－ＭＳ配备改性的ＢＰＸ５石英毛细柱分析了临清坳陷东部禹城洼陷禹参２井生油岩剖面，胜利油区不同成熟度的原油和生油岩样品的芳烃组成。发现芳烃色谱分布特征、脱羟基维生素Ｅ的β／α异构体比值、北～苯并荧蒽／苯并（ｅ）芘比值以及２，６＋２，７／１，５二甲基萘异构体比值均是沉积物的低—中熟热演化阶段的有效成熟度指标，脱羟基维生素Ｅ是低成熟的标志。新参数２，３，６／２，３，６＋１，２，５三甲基萘比值与１，３，６，７／１，３，６，７＋１，２，５，６四甲基萘比值图，可以确定低—高熟整个热演化阶段原油和生油岩的成熟度，并不受运移过程分馏效应的影响，对成熟度的变化反映灵敏
GC-MS equipped with modified BPX5 quartz capillary column was used to analyze the aromatic hydrocarbon composition of the crude oil and source rock samples with different maturity in Shengshu oil-rock profile of the Yu-shen 2 well in the east Yucheng sag of Linqing depression. It was found that the distribution characteristics of aromatic hydrocarbons, beta / alpha isomer ratio of dehydroxyvitamin E, the ratio of north to benzofluoranthene / benzo (e) pyrene and 2,6 + 2,7 / 1,5 dimethylnaphthalene isomers The ratios are all effective maturity indicators for the low-moderate thermal evolution stage of sediments, and dehydroxyvitamin E is a marker of low maturity. New parameters 2,3,6 / 2,3,6 + 1,2,5 trimethyl naphthalene and 1,3,6,7 / 1,3,6,7 + 1,2,5,6 tetramethylnaphthalene ratio diagram , It is possible to determine the maturity of the crude oil and the source rock from low to high temperature throughout the thermal evolution stage and not from the fractionation effect of the migration process and to reflect the change of maturity
