摘　　要：从地层和构造活动特点等方面探讨了右行走滑的塔拉斯—费尔干纳断裂对喀什凹陷地层、构造和油气地质特征等方面的控制作用。该断裂从晚三叠世开始影响喀什凹陷,对喀什凹陷的影响可以划分为两个阶段:晚三叠—中侏罗世期间主要在喀什凹陷形成很可能不相连的库孜贡苏和克孜勒陶断陷盆地,其中发育断陷盆地型下—中侏罗统烃源岩;新近纪—第四纪期间则主要形成相关的走滑变形,控制喀什凹陷的油气圈闭与油气成藏作用。The right-slip Talas-Ferganhna fault plays significant roles in controlling the strata, structures and petroleum geologic features in Kashi sag since Late Triassic. During the Late Triassic-Middle Jurassic, Kuzgongsu and Kezletao rifted-basins probably disconnected with each other occurred in the sag, with developed rifted-style source rocks of Lower-Middle Jurassic. During the Neogene-Quaternary, the relevant strike-slip deformation of the fault could form and controll the petroleum traps and accumulations in Kashi sag.
