摘　　要：从沉积及储层组合、油气运移系统等方面全面剖析了准噶尔盆地三台-北三台地区第三系油气成藏条件,建立了成藏模式,对未钻探区勘探潜力进行了预测;通过分析,认为该区第三系储层物性主体差,断裂更多地表现为封闭性,导致沟通深部油气源的运移体系不畅,致使第三系圈闭不能有效捕获和储集油气。圈闭又比较匮乏,主体勘探潜力不大。北25井西背斜紧邻多期活动的甘诃子北断裂,第三系可能发育较好的储层,相对有利,北25井西背斜应是钻探第三系的首选目标。Oil and Gas forming conditions of the third series in Junger Basin SanTai-North sanTai Area are totally analyzed from different aspects such as sedimentation,reservior combination and oil-gas migration,the oil-gas Forming Model is established in this paper,at the same time,prospection potential is predicted in area which has not been drilled.Through analysis,it is thought that the trap of third series in the area can not be captured and oil-gas can not be prevented from migration,as a resut,the trap is barren and prospection potential is little.However,North well 25 west anticlinal fault should be the first drilling objective in the third series comparatively.
