摘　　要：研究表明,渤海湾盆地石炭—二叠系煤成天然气伴生凝析油和第三系天然气伴生凝析油之间,K1、K2、P2与N2/P3等轻烃Mango参数存在较明显不同的变化规律,这表明Mango参数与源岩有机质类型密切相关,可用于不同成因类型天然气的判识。Based on the research of the light hydrocarbon of companion condensate of Permo - carboniferous coal - formed gas and Tertiary gas in Offshore Bohai Bay Basin, it is found that the Mango parameter is obvious varying between these two kinds of condensate. In other words, using the Mango parameter, such as K1 , K2 , and the light hydrocarbon compounds contents,as P2, N2/P3, can divide different kinds of condensate. It indicates that Mango parameters have close relationship with its organic matter types. But this method is still growing, which need more geological and experimental data to support its development, but it is valuable because that it may offer a new method to the gas genetic classification.
