严重生物降解原油GC-MS特征及油源对比

The GC - MS Characteristics and Oil - source Correlation of Severely Biodegraded Oil

图牧吉油砂位于松辽盆地边缘,搞清它的油源对于该地区的油气勘探有着十分重要的意义.气相色谱-质谱分析表明,该样品受到了严重的生物降解,部分用于对比的甾、萜烷生标标志物受到了降解,使与之有关的参数值发生了变化,给油源对比带来了困难.……

Tumuji oil sand is located in the margin of Songliao Basin, its oil - source research is very important for this region' petroleum exploration. The GC - MS analysis has shown that Tumuji oil sand has been severely biodegraded, some terpane and sterane compounds are not used to make oil - source correlation. We have selected anti - biodegraded tricyclic terpane as the correlative parameter to make correlation with three adjacent oils. It has suggested that Tumuji oil have from Nenjian and Qingsankou soure formations. This paper has provided an effective correlation method for severely biodegraded oils.
