| 摘 要： | 柴西南区岩性油藏勘探潜力较大,但是对岩性油藏形成过程的研究十分薄弱。在分析柴西南区主力烃源岩生、排烃史的基础上,根据储层显微荧光及流体包裹体均一温度特征,结合对岩性圈闭形成期次分析,深入分析了岩性油气藏形成过程。研究表明,柴西南区有两次主要的油气充注期:中新世中期和上新世末期;其岩性圈闭形成具有相对早期性和多期性,其主要形成期在渐新世末期和上新世末期。柴西南区岩性油气藏形成过程划分为两个阶段:成藏期及保存-破坏期。

| Abstract: | The lithologic pools have a great potential of resource in Southwestern Qaidam Basin,however,the study on hydrocarbon accumulation process is insufficient.In the paper,the hydrocarbon generation and expulsion history of the main source rocks in the lithologic pools of the Southwestern Qaidam Basin was analyzed,and the formation characteristics of local lithologic reservoirs was investigated on the basis of microscopic fluorescence and homogenization temperatures of fluid inclusions in reservoir. The result showed that there were two hydrocarbon-charging times in the Middle Miocene and the Late Pliocene. This area is characterized by the early-stage and multi-stage lithlogical traps which mainly formed in the Late Oligocene and the Late Pliocene. The formation process can be divided into two stages of accumulation period and preservation-destruction period. |
