摘　　要：霍尔果斯背斜位于准噶尔盆地南缘山前冲断带中段。以断层相关褶皱理论为基础,对背斜构造样式、构造演化及油气勘探潜力进行分析。认为霍尔果斯背斜为深部断层转折褶皱与浅部断层传播褶皱组成的复合型背斜,发育3期构造演化序列:深部断层转折褶皱发育期、中部反向断裂发育期及浅层霍玛吐断裂冲断改造期。古近系紫泥泉子组发育优质储层,是油气发现的主力层系,油气藏为高压、高凝、高产、带油环的大跨度高效油气藏;白垩系东沟组一段发育规模储层,储盖组合有效,是深化勘探的有利层系。Khorgos anticline is located in the middle of piedmont thrust belt in the southern margin of Junggar Basin.Based on the theory of fault-related fold,the structural style,structural evolution and oil and gas exploration potential of the anticline are analyzed in detail.The study shows that the Khorgos anticline is a composite anticline consisting of deep fault turning fold and shallow fault spreading fold.It has three stages of structural evolution sequence:deep fault turning fold,middle reverse fault developing stage,and shallow Huo-Ma-Tu fault thrusting reforming stage.Paleogene Ziniquanzi Formation has developed high-quality reservoirs,which are the main oil and gas discovery strata.The reservoirs are large-span and high-efficiency reservoirs with high pressure,high pour point,high yield and oil ring.In the first member of the Dong Gou formation,which is a beneficial layer for deepening exploration,the reservoir is developed and the reservoir cap assemblage is effective.
