惠民凹陷临南地区古近系沙三段咔唑类含氮化合物的地质意义

摘要

This paper deals with 3rd Member of Palaeogene Shahejie Formation in Linnan area of Huimin sag.Carbazoles data from 69 samples were analyzed and studied,and the results show that carbazole,methylcarbazoles,dimethylcarbazoles and benzolecarbazoles have close relationship with the buried depth,the maturity and the depositional setting.It is concluded that the contents and relative values of the carbazoles can be used as criteria of maturity and depositional setting in future studies.%分析和研究了69个样品的咔唑类含氮化合物数据,认为惠民凹陷临南地区沙三段咔唑类含氮化合物中的咔唑、甲基咔唑、二甲基咔唑及苯并咔唑等.与埋藏深度、成熟度和沉积环境之间关系密切.因此今后研究过程中可以考虑部分咔唑类含氮化合物的含量和比值作为成熟度指标和指相标志.
