Features of Fluid Inclusion and Their Implications for Hydrocarbon Charging Periods in the Eighth Member of the Shihezi Formation,Longdong Area, Ordos Basin
摘要
Abstract
This study reports the features of fluid inclusion in the eighth Mcmber of the Upper Paleozoic Shihezi Formation,Longdong area of the Ordos Basin,including the hosting minerals,morphology,homogenization temperatures and compositions.Combined with the stratigraphic burial history,we address the capturing events of fluid inclusion and their implicaitons for hydrocarbon filling history.Results show that the inclusions are hosted in three types of minerals with three types of morphologies.The homogenization temperature of fluid inclusion ranges in 90～170 ℃,with the peak at 100～130 ℃,and the compositions of fluid inclusion is CH4 and CO2.These imply that there are three capturing events of fluid inclusion during the Late Jurassic to the Early Cretaceous in the Lengdong area.Combined homogenization temperature of fluid inclusion with the stratigrahic burial history,it is suggested that the study area had one-phase gas filling in the Late Jurassic to the Early Cretaceous.关键词
