摘　　要：为进一步阐明塔里木盆地泥盆系东河砂岩油气分布规律、明确油气勘探方向,分析了东河砂岩油气成藏相关的资料,并对其成藏特征和分布规律进行了深入研究。研究认为,塔里木盆地东河砂岩油气分布受控于海西运动期断裂带和地层尖灭。受海西运动期构造控制的圈闭能否成藏,取决于圈闭的规模和距离油源的距离,色力布亚断裂带东段是此类油气勘探的有利地区;受地层尖灭控制的圈闭能否成藏,取决于圈闭底板岩性和其是否处于构造高部位,顺托果勒低隆南北两侧以及阿瓦提坳陷北部是此类油气勘探最有利的地区。In order to further illuminate the oil and gas distribution of the Devonian Donghe sandstone,and to explicitly determine the oil-gas exploration direction in Tarim basin,the paper analyzes the data related to the hydrocarbon accumulation in Donghe sandstone,andstudies its hydrocarbon accumulation characteristics and oil-gas distribution.It is concluded that the oil and gas distribution in Donghesandstone of Tarim basin is controlled by fault belt of Hercynian movement period and stratigraphic pinchout.Wether the traps constrainedby the structures of Hercynian movement period could trap oil and gas or not depends on the trap sizes and the distance from oil source,and the eastern section of the Selibuya fault belt is the favorable area for oil and gas exploration.Wether the traps controlled by stratigraphic pinchout could trap oil and gas or not depends on the lithologies of the trap floor and their positions in structures,and the southern andnorthern sides of Shuntuoguole low uplift and the northern Awati depression are the most favorable areas for oil and gas exploration.
