摘要
mary" name="EnDivSummary">Based on the reconstruction of burial history,thermal history and the analysis of fluid inclusion samples collected from the K2d-E1-2z of Huo-Ma-Tu structural belt in the south of Junggar Basin,the stages of hydrocarbon accumulation in studied area were determined.The evolution of paleo-fluid potentials and characteristics in E1-2z during different stages of hydrocarbon accumulation process were reconstructed through the data of the fluid inclusions.The results show that the studied area experienced two periods of hydrocarbon accumulation process,the first period mainly occurred in middle-late Miocene(about 14~9 Ma),while the second period mainly occurred in middle-late Pliocene(about 3.7~2.5 Ma).The distribution characteristics of paleo-fluid potential during these two periods of hydrocarbon accumulation are significantly different.In the first period,Tugulu anticline area was in the lowest potential area,which became the favorable area for accumulation of oil generated from Cretaceous source rocks.In the second period,Manasi anticline area became the lowest potential area,in which the gas generated by coal measures source rocks in the middle and lower Jurassic accumulated.
