摘　　要：将构造演化过程与油气成藏过程有机结合,深入剖析新疆火焰山逆冲推覆构造带的演化过程、动力学机制、构造模式,及其与该区油气成藏的关系。研究表明,地震多发造就了该区油气生成运移的地球化学环境,火焰山构造带从早侏罗世开始的断褶运动和品质良好的烃源岩是有机质演化生烃的重要条件,中侏罗统为主要的储集层段,晚侏罗世沉积的一套厚800～1000 m的棕红色泥岩是侏罗纪油气藏的区域性盖层,断褶构造运动为油气运移提供动力。该地区的勘探已见相当数量的油气显示,以中小油气田为主。火焰山东端与七克台之间的地带是目前勘探的重点区域。Combining the process of structure evolution with oil and gas accumulation,the paper deeply analyzes the evolution,dynamic mechanism,structural model,and its relationship with hydrocarbon accumulations of thrusting-nappe structure belt.The research result shows that constant earthquake created the geochemical environment for generation and migration of hydrocarbon,and the folding movement started in Early Jurassic and the good quality source rocks were the important factors for organic matter evolution and hydrocarbon.Middle Jurassic was the main reservoir intervals and the brown mudstone deposited 800~1000m of Late Jurassic was the regional caprock.Fault-fold tectonic movements provided the force for the hydrocarbon migration.Exploration in the area has been seen lots of oil-gas,mainly with small and medium oil-gas fields.The area between the eastern end of Huoyanshan and Qiketai is the key exploration areas now.
