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.
The study of the geometry and kinematics of the piedmont fold belt belongs to the forefront topic of tectonic geology and is also a concern in the global exploration and development of oil and gas in the Piedmont basin.Based on two-dimensional seismic profiles, drilling and logging data and geological mapping data, Two kinds of fault geometry and kinematics models in the east of Kuqa Depression are plotted, and the distribution of breakage intervals of the Tuzuoke fault and the eastern Qiuerritage fault and the distribution of the displacement of the eastern Qiu’erlige anticline are plotted. The research shows that the Kuqa Two types of faults were developed in the eastern depression. During the Paleogene, high-angle thrust faults developed, resulting in the uplift of the basement of the piedmont and the denudation of Cretaceous-Paleogene. In the Pliocene, the low-angle thrust faults developed in the Kuqa depression Mesozoic - Cenozoic deformation, the formation of the basin hidden belly hidden tile thrust structure.
