| 摘 要： | 原油的含氮化合物总量及其组成特征不仅受原油运移距离影响,而且还受成油母质类型和成熟度影响.对南阳凹陷27个原油含氮化合物的研究表明,其油气运移指向的规律性不强,原因主要是由于原油运移距离较短,地质色层效应不明显.魏岗南部和北部原油的成熟度差异较大,但含氮化合物组成特征总体上非常相似,表明南阳凹陷原油的含氮化合物总量及其组成主要受控于成油母质类型.

| Abstract: | Former study indicated that total concentrations and distributions of nitrogen compounds of oils are not only influenced by oil secondary migration,but also influenced by the type and maturity of the organic matter. Direction of oil migration in Nanyang Depression has been studied by means of the data of nitrogen compounds in 27 oils.Interpretation of oil secondary migration direction is not very well from the distributions of carbazoles and bencarbazoles in this area because of the limited distance between oil and source-rocks.The oil maturations in the northern and southern Weigang regions are difference in evidence from steroid biomarkers,but the distributions of carbazoles and bencarbazoles are very similar.This indicates that the total concentrations and distributions of nitrogen compounds of oils are controlled by the type of the origin organic matter. |
