摘　　要：在吸收前人研究成果的基础上,通过原油族群的划分和流体包裹体均一化温度的测定和分析,认为在准噶尔盆地三台-北三台-北三台西南斜坡带存在早燕山期、晚燕山期和喜马拉雅期3个成藏期,构成了该地区的成藏过程。早燕山期以博格达山前二叠系为烃源灶,油气自山前凹陷由南向北沿三台-北三台构造梁运移最远至北三台南坡,晚燕山期以阜康凹陷二叠系和侏罗系为烃源灶,油气自凹陷向北东、东和南东方向运移,喜马拉雅期油气运移的总格局与晚燕山期一致,在三台-北三台凸起高部位油气以垂向运移再分配为主。Based on the existing research results,classification of crude oil clusters and fluid inclusion homo-temperature analysis,the authors of this article draw the following conclusions,i.e.,there exist,in the area of Santai-Beisantai-Southwestern slope of Beisantai,three formation periods of oil and gas pools,early Yanshan period,late Yanshan period and Himalayan period.During the early Yanshan period,Permian mudstone in the Begeda fore-mountain sag was the source kitchen and petroleum migration was from south to north along the Santai-Beisantai uplift,reaching to the southern slope of Beisantai uplift.During late Yanshan period,Permian and Jurassic mudstones of Fukang sag were the source kitchen and petroleum migration was from the sag to northeast,east and southeast orientation.During Himalayan period,petroleum migration had the same framework as during late Yanshan period in the regional scale,characterized by vertical remigration in the high of Santai-Beisantai uplift.
