摘要
对柴达木盆地油砂山8块油砂样品饱和烃馏分进行气相色谱-质谱(GC-MS)分析,生物标志化合物特征显示油砂山油砂油主要形成于高盐湖相。结合异戊二烯烃、甾烷、萜烷分布特征显示:油砂山地区油砂油母质来自水生生物和高等植物双重输入,且水生生物较高等植物稍占优势;利用C_(29)ββ/(ββ+αα)和C_(29)ααα-20S/20(S+R)关系图,结合Ts/Tm、C_(31)藿烷异构体、重排甾烷/规则甾烷参数共同指示油砂山油砂表现为低成熟-中等成熟特征。
The saturated distillate of 8 oil sands samples from Youshashan Oil Field in the west part of Qaidam Basin were analyzed with gas chromatography and mass spectrometry（GC-MS）technology.The composition and distribution characteristics of biomarker compounds of them indicated that the oil sands oil of Youshashan Oil Field were formed high Oil Field salinity environments.According to distribution characteristic of isoprene hydrocarbons,steroids and terpenoids,the parent material source of Youshashan Oil Field is aquatic organism higher than higher plant,with some input of algae.The relationship diagrams between C29ββ/（ββ＋αα）and C29ααα-20 S/20（S＋R）,and combination of Ts/Tm,C31 hopane isomers,diasterane/regular steroids.The results show that there were similar low to middle maturity in Youshashan Oil Field.
