Characteristics and Significance of Fluid Inclusions from Majiagou Formation, Yichuan-Huangling Area, Ordos Basin
摘要
With methods such as polarizing and fluorescence microscope observation,homogeneous temperature and ice point temperature measurement and analysis of composition,a systematic study is conducted to acquire petrographic,salinity and homogenization temperature of fluid inclusions from Majiagou Formation of Yichuan-Huangling area in the Ordos basin.Finally,it can be inferredthat fluid inclusion of Majiagou Formation can be divided into two stages.The occurrence of bitumen inclusion demonstrates that paleo-oil reservoir may be once reconstructed.Besides,paleo-oil and-gas reservoir formation should be in early Jurassic-middle Jurassic and early Cretaceous respectively.
