为了探讨生物标志化合物和吡咯类含氮化合物作为油气运移指标的有效性，以塔里木盆地轮南油田、柴达木盆地尕斯库勒油田为例，对海相成熟油、盐湖相低熟油中烃类组分（甾、萜类化合物）和非烃组分（吡咯类含氮化合物）的分布特征进行了对比研究。定量分析结果显示，不同类型原油中烃类生物标志物差异显著，受原始母质类型、成熟度的影响大，而吡咯类化合物的种类与分布型式相对变化较小，具有相对较好的稳定性。确认吡咯类含氮化合物可显示相对较强的油气运移分馏效应。产生油气运移分馏作用的根本原因是极性作用，吡咯类含氮化合物比甾、萜类化合物的运移分馏效应强，可能是二者产生极性差异的机理不同。吡咯类含氮化合物作为油气运移示踪剂有其独特的优势。
In order to investigate the effectiveness of biomarkers and pyrrole-type nitrogen compounds as hydrocarbon migration indicators, taking Gasseule Oilfield in Lunnan Oilfield and Qaidam Basin in Tarim Basin as an example, the effects of marine mature oil, salt lake low cooking oil The distribution characteristics of hydrocarbon components (sterols, terpenoids) and non-hydrocarbon components (pyrrole nitrogen-containing compounds) were compared. Quantitative analysis showed that there were significant differences in hydrocarbon biomarkers among different types of crude oil, which were greatly affected by the type and maturity of the original parent materials. However, the relative change in the types and distribution patterns of pyrrole-based compounds was relatively small with relatively good stability. The pyrrole-type nitrogen-containing compounds were confirmed to show relatively strong hydrocarbon migration fractionation effects. The fundamental reason for hydrocarbon migration and fractionation is the polar effect. The migration and fractionation effects of pyrrole nitrogen-containing compounds are stronger than those of sterols and terpenoids, which may be due to the different mechanism of polarity difference between the two. Pyrrole nitrogen compounds have their unique advantages as tracer for hydrocarbon migration.
