| 摘 要： | 利用杨米涧地区杨2井区长2油组原油的原油物性、族组成以及饱和烃、芳烃色谱-质谱资料，分析了原油的地球化学特征。并对原油族群进行划分；在此基础上，利用原油含氮化合物参数对研究区长2油组原油充注方向进行了探讨，结果显示长2油组原油为来源于湖相弱还原环境的成熟原油。陆源有机质为主要的生烃母质，并且原油属于同-石油族群．其充注方向为自西北向东南方向。 |

| Abstract: | According to the data of oil physical characters, group-composition, the GC-MS of saturated hydrocarbon and aromatic hydrocarbons of Chang 2 oil group from Wellblock Yang2 of Yangmijian Area, the geochemical characters of the oil were analyzed and the oil groups were classified. Base on these, the parameters of the Nitrogen compounds were used to study the migration direction of the Chang2 oil group in the study area, it indicated that the Chang 2 oil group derived from the lacustrine strata source- rocks deposed under weak redox condition. The precursor type of the oil was main terrestrial organic matter. The crude oil is mature and it belongs to the same oil group. The migration direction of the Chang2 oil group is from the northwest to southeast. |
