摘　　要：吐哈盆地中下侏罗统水西沟群是一套厚达２０００ｍ的河沼－湖沼相煤系地层，其中的煤岩及暗色泥岩是已发现油气藏的主要源岩。形成于燕山期的古构造控制了油气富集，纵向上油气主要在中侏罗统聚集成藏。油气以垂向运移及短距离侧向运移为主，断裂控制了油气运、聚、保、散。多种构造样式与砂体交互配置，形成多种油气藏类型。The Early to Middle Jurassic Shuixigou Group in Turpan Hami basin is a series of coal measure strata with a thickness of 2 000 m .Coal and dark coloured mudstone in the group have been proved to be the main source rock of the discovered hydrocarbon reservoirs,The paleostructures formed in the Yanshanian movement conrtolled the enrichment of hydrocarbon,and the hydrocarbon accumulated mainly in the Middle Jurassic,vertical and short distance horizontal migration dominated in the basin ,the faults controlled the migration,accumulation,preservation and escape of oil and gas.Combination of multiple structural patterns and multiple sand bodies resulted in muliple reserviors,which lead to complex oil and gas accumulation zones.
