通过胜利油区某探区烃类组份的相关性特征、三维荧光特征、甲烷碳同位素特征及烃类组份的某些比值特征等４项参数的对比分析，认为该区土壤吸附烃组份异常的成因主要属热解成因的油田伴生气或凝析气，基本可排除地表生物降解成因气、人工污染气、煤成气形成异常的可能性。土壤吸附烃组份异常推断为深部油气藏在地表的响应。
According to the comparative analysis of the four parameters of the correlation characteristics, three-dimensional fluorescence characteristics, methane carbon isotope characteristics and some ratio characteristics of hydrocarbon components in a certain exploration area of Shengli Oil Region, it is concluded that the adsorption of hydrocarbon components The main cause of anomaly is associated gas or gas condensate in the oilfield of pyrolysis, which can basically eliminate the possibility of formation of abnormal biogenic degradation gas, artificial pollution gas and coal gas. Anomalies of soil adsorbed hydrocarbon components are inferred as responses of deep reservoirs to the surface.
