系统采集塔里木盆地库车坳陷、柯坪隆起、巴楚隆起等露头区岩样和雅克拉地区井下岩心 ,样品涉及三大岩类 (变质岩、岩浆岩、沉积岩 )、3 3个层位 (Pt—N2 k)、15种岩性 ,测试和统计了 2 5 1组岩石力学参数 (弹性模量 ,泊松比 ,抗压强度 ) ,建立了塔里木盆地综合地层岩石力学剖面 ,为研究盆地变形特征、变形规律提供了实验地质依据。分析塔里木盆地组合地层岩石力学特性、变形习性及主要影响因素 ,结合前人研究成果 ,提出塔里木盆地发育 5个主要滑脱层系 ,完善了塔里木盆地滑脱层系和构造变形层的划分。
The samples were collected from the outcrops of the Kuche depression, Keping uplift and Bachu uplift, and the core of the Yakela region. The samples involved three major types of rocks (metamorphic rocks, magmatic rocks and sedimentary rocks) -N2 k) and 15 lithologies. The mechanical parameters (elastic modulus, Poisson’s ratio and compressive strength) of 251 groups of rocks were tested and counted. The rock mechanics profile of the comprehensive formation in Tarim Basin was established. In order to study the deformation characteristics of the basin , Deformation law provides experimental geological basis. Based on the previous research results, five major sliding systems are developed in the Tarim Basin, and the division of the detachment strata and the tectonic deformation layer in the Tarim Basin is perfected.
