| 摘 要： | 油源对比常常并非易事,凝析油由于甾萜类生物标志化合物的贫乏这一特殊性,增加了其油源对比的难度.根据松辽盆地齐家古龙凹陷英51井凝析气层下伏有常规油气层的特点,先选择用反映油藏连通性的色谱指纹和具有示踪作用的单体烃同位素进行油油对比,证实了凝析气层的油气与下伏油气同源;在此基础上,根据源岩和原油色谱大量数据的统计,用姥鲛烷、植烷参数的差异性论证了英51井油气皆来自青山口组.

| Abstract: | It is difficult to make oil-source correlation,and the particularity of lacking steroid and diterpenoid biomarkers in condensate oil makes it more difficult.According to the characteristics of conventional oil and gas layers of condensate gas of Well Ying 51 in Qijia-Gulong sag in Songliao Basin,chromatographic fingerprints that can reflect the connectivity of reservoir and isotope composition of hydrocarbon monomers that has tracer role are chosen to contract the oil-oil correlation.It is approved that the oil in condensate pool and underlie oil come from the same source.On the basis of large amounts of data statistics about source rock and crude oil chromatography,it is the concluded that the hydrocarbon of Well Ying 51 comes from Qingshankou Formation using discrepancy of parameter between the pristine and phytane. |
