摘　　要：通过实测碳排放因子计算公式理论分析及油气田典型燃料天然气实例分析,探索燃料天然气组分特征对实测碳排放因子的影响。结果表明:各生产系统使用的油气田燃料天然气含碳原子数量较多的组分含量越多,实测含碳量碳排放因子及实测低位发热量碳排放因子越大,含碳原子数量较少的组分或H_(2)、O_(2)、N_(2)、He不含碳的组分含量越多,实测含碳量碳排放因子及实测低位发热量碳排放因子越小;除实测方法系统性差异外,一定含量的CO_(2),是导致油气田燃料天然气实测低位发热量碳排放因子与实测含碳量碳排放因子之间存在显著差异的重要原因;各类燃料天然气碳排放因子存在普遍性差异,干气的实测碳排放因子明显比湿气的小。上述结论将为油气田燃料天然气碳排放核算提供技术支持。The influences of fuel natural gas composition characteristics on measured carbon emission factors are explored through the theory analysis of measured carbon emission factors formula and the cases analysis of typical fuel natural gas in oil and gas field.The results show that the higher the content of components with more carbon atoms in the natural gas used as fuel of each production system in oil and gas fields,the greater the carbon emission factor from measured carbon content and that from measured low calorific value.The higher the content of components with less carbon atoms or components without carbon such as H_(2),O_(2),N_(2),He in natural gas used as fuel in oil and gas fields,the smaller the carbon emission factor from measured carbon content and that from measured low calorific value.What's more,in addition to systematic differences between measurement methods,a certain amount of CO_(2)is an important reason for the significant difference between the carbon emission factor from measured carbon content and that from measured low calorific value of natural gas used in oil and gas fields.In addition,there are universal differences in various carbon emission factors of fuel natural gases in oil and gas fields,and the measured carbon emission factors of dry gas are significantly smaller than those of wet gas.Most importantly,the above conclusions will be provided technical support for the carbon emission accounting for fuel natural gas in oil and gas fields.
