原油芳烃中的二苯并噻吩（DBT）、二苯并呋喃（DBF）和芴（F）及其同系物来源于同一种前体，其含量可指示原油的原始沉积环境。利用南阳凹陷、江汉盆地、准噶尔盆地和珠江口盆地64个原油样品的芳烃∑ SF、∑ OF和∑ F数据，可以较好地判别原油的原生环境，其效果优于简单的三角形图。利用∑ SF和∑ OF比与Pr/Ph的关系图以及γ蜡烷指数与Pr/Ph的关系图来区分环境。
The dibenzothiophene (DBT),dibenzofuran (DBF) and fluorene (F) and their homologues of the aromatic hydrocarbons of the crude oils are considered that they originated from the same precursor,and their contents can indicate primary sedimentary environment of them. The data of the ∑ SF,the ∑ OF and the ∑ F of the aromatic hydrocarbons in 64 oil samples which are from the Nanyang depression,the Jianghan,the Junggar,and the Zhujiangkou basins in China can be use to distinguish from primary environment of the crude oils with a better effect than the simple triangle figure. Using the diagram of ∑ SF and ∑ OF ratio versus Pr/Ph to distinguish from environment is as well as using that of gammacerane index versus Pr/Ph.
