摘　　要：构造演化与油气成藏相结合的研究方法,对于塔里木孔雀河斜坡的油气勘探具有重要的指导意义.经研究认为研究区的构造运动,主要分为震旦纪到早奥陶世的拉张阶段、中晚奥陶世到侏罗纪的挤压隆升剥蚀阶段以及白垩纪到新生代的前陆盆地斜坡稳定沉降阶段.构造是研究区油气成藏的主控因素,构造控制了生储盖发育与油气运移通道等成藏要素组合.最后通过仔细对比分析,认为该区维马克-开屏构造带以及龙口构造带具有良好的勘探潜力.The research method of combining the structural evolution with hydrocarbon accumulation has important directive function for oil ＆ gas exploration in Kongquehe slope of Tarim Basin. We have concluded that the structural movement of the area can be divided into three stages： The stretching stage from Simian to early Ordovician, the extrusion and rising stage from middle and late Ordovician to Jurassic and stable depressed stage of foreland basin slope from Cretaceous to Neozoic. Structural which has controlled many factors, such as the development of oil generation, source rock, cap rock and the fault, is the main control factor of hYdrocarbon migration and accumulation. Finally, through comparison and analysis, we believe that Weimake-Kaiping and Longkou structural belts possess better potential for exploration.
