| 摘 要： | 对Mango的轻烃稳态成因理论进行了综述：基于大量实际分析资料，Mango发现轻烃的形成受一种化学过程控制，且有4个C，异构化合物的相对组成有显著的不变性，即轻烃稳态成因模式；基于该模式，Mango建立了轻烃参数与生油层最大埋深温度的关系，同时发现参数K1、1（2的不同来源于有机质类型不同。在该理论基础上，通过对苏北盆地湖相油和海相油气轻烃的分析，探讨了轻烃参数K1、K2在确定油气母质类型方面的应用，同时依据轻烃参数2，4．／2，3-DMP与最大埋深温度关系式计算了苏北湖相油与海相油气的生成温度，结果显示湖相油生成温度与甾烷C2920S／（S＋R）参数有较好的相关性，处于成熟阶段；海相油气生成温度显著高于湖相油，处于成熟晚期阶段。

| Abstract: | The authors summarized the genetic theory of light carbon stable state by Mango. Based on large actual data, Mango found that the formation of light-hydrocarbon was controlled by a chemical process and the obvious invariance of relevant components of 4 C7 isomers that was the stable genetic model of light hydrocarbon. According to this model, Mango established the relationship between the light hydrocarbon parameter and the max-burial temperature; and discovered the difference of KI ,K2 parameters from distinct type of organic material. The authors analyzed the light hydrocarbon of lacustrine oils and marine hydrocarbon in northern Jiangsu Basin, and probed K1 ,K2 into use of determination of hydrocarbon originated from marine or lacustrine materials; and calculated the formation temperature of lacustrine oils and marine hydrocarbons. The results showed the formation temperature of lacustrine oils, which was in mature stage, was of fine correlation to sterane C2920S/（ S ＋ R）, and the formation temperature of marine hydrocarbons, which was in late mature stage, was higher than that for lacustrine oils. |
