摘要： 根据含油包裹体丰度、颗粒荧光定量、包裹体均一温度等分析,对柴达木盆地西部跃进一号、油砂山、南翼山、尖顶山等4个典型构造的古近-新近系油气充注研究表明,不同构造油气充注所需的时间与强度不同：跃进一号、油砂山构造发生过较强的油气充注,充注期主要为$N^{1}_{2}$-$N^{3}_{2}$,含油包裹体丰度值高（多数为4%~10%）,颗粒荧光强度也高（多大于50 pc）;南翼山和尖顶山构造发生较有限的油气充注,充注期主要为$N^{2}_{2}$-$N^{3}_{2}$,含油包裹体丰度值较低（大多数样品不超过4%）,颗粒荧光定量强度也较低（多小于50 pc）。关键词：柴达木盆地;油气充注;含油包裹体丰度;颗粒荧光定量;包裹体均一温度

Abstract: According to analyses of grains with oil inclusions (GOI), quantitative grain fluorescence (QGF), homogenization temperature of fluid inclusion (HTI), the Tertiary oil charges to four typical structures (Yuejing-1, Youshashan, Nanyishan and Jiandingshan) in Western Qaidam basin are studied in this paper, showing that there exist charges of difference: for Yuejing-1 and Youshashan structures stronger oil charges occur during $N^{1}_{2}$-$N^{3}_{2}$, with high GOI value (mostly 4%~10%) and high QGF intensity (more than 50 pc); for Nanyishan and Jiandingshan structures relatively weak oil charges appear during $N^{2}_{2}$-$N^{3}_{2}$, with lower GOI value (mostly less than 4%) and lower QGF intensity (less than 50 pc) in their reservoirs.

Key words: Qaidam basin, oil charge, oil inclusion abundance, quantitative grain fluorescence, fluid inclusion, homogeneous temperature
