摘要： 准噶尔盆地东南柴窝堡凹陷自晚石炭世以来经历了4个发展演化阶段,形成了多层烃源岩层、储集岩层和盖层。上二叠统芦草沟组、红雁池组为主力烃源岩层和主要勘探目的层,上三叠统-侏罗系为区域性盖层;主力烃源岩层在凹陷北部较南部发育,但其成熟度北部较南部低;主力烃源岩层于三叠纪末期进入生油门限,侏罗纪末期达生油高峰期,与西部及北部圈闭的形成期相匹配。该凹陷三葛庄凸起及北部深大断裂带附近是油气勘探的主要方向。

Abstract: Chaiwopu seg in southeastern Junggar basin went through 4 stages in its development and evolution since Late Carboniferous, deposited multiple source rocks, reservoir rocks and cap rocks. The Lucaogou formation and Hongyanchi formation of Upper Permian are regarded as major source rocks and main prospecting target; Upper Triassic-Jurassic as regional cap rocks, the major source rocks are more developed in north than south, but their maturity of organic matter is higher in south than in north. They entered the "oil window" in the end of Triassic and reached the peak of oil generation in the end of Jurassic, which matches the trap-forming period in west and north parts of the seg. Sangezhuang salient and near the north deep fault belt of it are the primary target for oil-gas exploration.

Key words: Junggar basin, Chaiwopu, seg, geologic feature, exploratory target
