摘　　要：准东地区油气资源丰富,正确认识该区的油气成藏条件及成藏模式,对准东地区有利勘探区带的优选和评价有重要意义。综合利用地质、地球物理、地球化学等手段,分析了该区油气成藏条件及成藏模式。研究表明:准东地区成藏具有南北分带的特征,对比分析了南北部烃源岩、储层、圈闭以及保存等成藏条件,南北差异较为明显;准东地区可分为3个复合油气系统,即阜康复合油气系统、东道海子-大井复合油气系统和吉木萨尔复合油气系统,对油气系统特征进行分析,在此基础上,提出了自石炭系到三叠系的5种油气成藏模式,并对典型成藏模式进行实例解析,最终提出了准东地区的油气富集的5大规律。In the east Junggar Area,hydrocarbon resources were enriched,it was of great significance of correct understanding of the reservoir-forming conditions and its accumulation rules.Reservoir-forming condition and accumulation pattern in the area were integrally analyzed by using geological,geophysical and geochemical means.The results show that in the area,hydrocarbon accumulation has the feature of north-south zoning,the reservoir-forming conditions between the north and the south were analyzed,such as source rocks,reservoirs and traps,it indicates that there exists obvious difference between the north and south area.The area can be divided into 3 composite oil and gas systems,inclucing FuKang,Dongdaohaizi-Dajing and Jimusaer oil systems.Base on the features of systems,it is proposed that there exist 5 types of hydrocarbon and accumulation modes,the typical modes are analyzed,Finally,5 accumulation rules are proposed.
