摘要
Junggar Basin is a transpressional superimposed basin in western China.Two sets of oil-bearing measures developed in the basin.Abnormal pressure was generally widespread.Indosinian,Yanshanian and Himalayan structural activities and main three hydrocarbon charging processes were undergone in terrestrial time,with hydrocarbon distribution complex.To make clear the hydrocarbon accumulation regularity,hydrocarbon charging features in three key stages of geological historical period is analyzed in terms of hydrocarbon accumulation stage through palaeostructure reconstruction.Inner coupling relationships among fracture conducting system,unconformity surface,abnormal pressure and hydrocarbon evolution of source rock are dynamically analyzed.Process evolution pattern of hydrocarbon charging and adjustment of geological historical stage has been established,which makes clear the main control factors of hydrocarbon accumulation during hydrocarbon charging at different periods.
