摘要： 在烃源确认的基础上, 通过储集层流体包裹体分析及其均一温度的研究, 并结合烃源岩的热演化史和储集层地温史, 按照油气生成、运移、聚集的阶段性理论, 发现并证实狮子沟构造油气存在3个油气成藏期, 即E23沉积期、N12沉积末期和N32沉积末期, 分别对应E1+2 烃源岩开始生油期、E1+2-E13烃源岩生油高峰期和E23烃源岩生油高峰期。最后,根据成藏过程和成藏历史分析, 结合构造演化史建立了相应的油气成藏模式。

Abstract: This paper affirms the hydrocarbon source, studies the fluid inclusion and homogenization temperature based on the source rock thermal evolution and reservoir geothermal history in Shizigou field. By means of staging theory of petroleum generation, migration and accumulation, it is suggested that there exist three stages of hydrocarbon accumulations in Shizigou structure, they are E3 2, late N2 1 and late N2 3, which correspond to E1+2 primary oil generation stage, E1+2-E3 1 peak oil generation stage and E3 2 peak oil generation stage of source rocks, respectively. Finally, according to the process and history analysis of hydrocarbon accumulation, this paper presents the corresponding reservoir formation models in this area.

Key words: Qaidam basin, Shizigou field, source rock, hydrocarbon accumulation, model
