%X 山前逆冲褶皱带的几何学和运动学研究属于构造地质学前沿课题，也是全球山前盆地油气勘探开发所关注的问题.综合二维地震剖面、钻测井数据、地质填图资料，建立了库车坳陷东部两类断层几何学和运动学模型，绘制了吐孜洛克断层和东秋里塔格断层断距分布图以及东秋里塔格背斜位移缩短量分布图.研究资料表明库车坳陷东部发育两种类型断层，古近纪发育高角度逆冲断层，造成山前基底抬升，白垩系-古近系被剥蚀；上新世发育低角度逆冲断层，引发库车坳陷中生界-新生界变形，形成盆地腹部隐伏的叠瓦状逆冲构造.<br>Geometry and kinematics analysis of thrustrelated fold system in piedmond is a frontier subject of structure and tectonics. These concepts and technical methods are relevant for the exploration and exploitation of hydrocarbon systems in piedmont basins worldwide. The geometry and kinematics models of the faults and folds are established by using the 2D seismic profiles, drilling well logging data, and geological mapping data in the eastern Kuqa depression in the piedmont of Tianshan Mountains, China. The fault throw maps of the Tuziluke fault and the eastern Qiulitag and the shorting map of the eastern Qiulitag anticline have been drew. The results reveal that there are two types of fault in the eastern Kuqa depression, i.e. the steeply basementinvolved faults and the low dipping thrust faults. In Tertiary, the steeply faults made the basement uplift and the MesoCenozoic squence erosion in the piedmont of Tianshan. The low dipping faults develop in Pliocene, which was detachment in the lower of Mesozoic and formed the blind imbricate thrustrelated fold system in the Kuqa basin
