Abstract

With methods of polarizing and fluorescence microscope observation,micro-thermometry etc.,fluid inclusions of 24 Upper Paleozoic sandstone samples from 16 wells in southwest Ordos Basin were comprehensively tested in this paper.On the basis of research on burial history,petrographic characteristics of fluid inclusions and homogeneous temperature,ice point temperature of associated aqueous inclusions from main production layers in Shanxi Formation and He 8 section,charging periods of natural gas in tight reservoir of study area can be inferred.The results show as follows.Homogeneous temperature of aqueous inclusion,associated with gaseous hydrocarbon,were 100-170℃.Homogeneous temperature and ice temperature show normal continuous distribution,which means the gas charging happened during Middle Jurassic-Early Cretaceous(200-100Ma).Component of gas inclusion in healed micro-crack is mainly CH4,homogeneous temperature of aqueous inclusion,associated with gaseous hydrocarbon,was 140-170℃,which means the mainly gas charging occurred during Early Cretaceous(155-100Ma).It is concluded that Paleozoic gas accumulation in the study area is a continuous and slow process,and the main charging period is Early Cretaceous.
