摘　　要：准噶尔盆地西北缘中拐凸起佳木河组以碎屑岩为主,为夹部分火山岩、火山碎屑岩的混积地层,三级层序PSQ1、PSQ2、PSQ3与前期的中、下亚组有一定的对应关系,而上亚组在区内遭受剥蚀,分布局限。通过岩心观察与描述,充分利用录井、测井资料,在高分辨率层序地层学理论指导下,进行了佳木河组四级层序的划分对比,建立起中拐地区二叠系佳木河组层序地层模式并明确各层序的沉积特征,对下一步有利区的优选有重要的指导意义。Jamuhe Formation in Zhongguai Bulge at northwest margin of Junggar Basin is dominated by clastic rock,with local interbeds of volcanic rock and volcaniclastic rock. The three-order sequence( PSQ1,PSQ2 and PSQ3) has some corresponding relations with middle and lower sub-formation at the early stage. However,the upper sub-formation is limited in distribution in the area due to erosion. Through observation and description of cores and with mudlog and logging data and the theory of high-resolution sequence stratigraphy,the 4th-order sequence in Jiamuhe Formation is divided and compared to establish the sequence stratigraphic mode of Jiamuhe Formation,Permian,in Zhongguai Bulge,and identify the sedimentary features of each sequence. The results are of great significance to the selection of favorable areas.
