该文对比分析了库车坳陷与塔西南坳陷的受力环境、变形层、形变区、滑脱层系,认为两者在构造变形方面存在明显差异。库车坳陷的应力特征以压性为主,横向上形变特征差异较小,纵向上由北向南变形强度逐渐减弱;塔西南坳陷的应力特征,在不同的边界条件下,表现为很强的扭动特征,构造变形在平面上变化较大,不同区块主形变期及形变特点差异明显,造成深坳陷及麦盖提斜坡带构造类圈闭不发育、断裂垂向输导作用较差。
This paper compares and analyzes the stress environment, deformation layer, deformation zone and slip-off strata between Kuqa Depression and the southwestern Tarim Basin. It is considered that there are obvious differences between the two in tectonic deformation. The stress characteristics of the Kuqa Depression are mainly compressive, with little difference in deformation characteristics in the transverse direction, and the deformation strength gradually decreases from north to south in the longitudinal direction. The stress characteristics in the southwestern Tarim Basin show a strong under different boundary conditions The tectonic deformation changes greatly in the plane. The main deformation and deformation characteristics of the different blocks have obvious differences, resulting in the undeveloped tectonic traps in the deep depression and the Maigaiti slope belt and the vertical fracture guiding effect difference.
