摘要

摘要: 通过单偏光、荧光显微镜和显微冷热台测温观察等方法,对鄂尔多斯盆地延长组长2段和长6段内流体包裹体系统进行研究,归纳流体包裹体岩相学、均一温度和冰点温度等特征,结合盆地热演化史分析推测出储层内烃类充注史,并恢复研究区长6段早白垩世末期的古流体势。研究结果显示,研究区延长组内长2段和长6段内主要发生过一期油气充注,对应的地质历史时间为早白垩世中期(120~100 Ma)。

Abstract: With methods such as polarizing and fluorescence microscope observation, homogeneous temperature and ice point temperature measurement and analysis of composition, a systematic study was conducted to acquire petrographic, salinity and homogenization temperature of fluid inclusions in the Yanchang Formation of the Triassic reservoir in the Ordos Basin. Combined with the thermal evolution of basin, fluid injection history and corresponding paleo-fluid potential were constituted. The oil and gas accumulations of reservoirs in the Chang2 and Chang6 sections were characterized by one stage, and might happen in the Middle Cretaceous, about 120-100 Ma.
