| 摘 要： | 为了定量地研究塔里木北部地区区域的层次结构．拆离构造，特别是同油气地质、圈闭构造密切相关的沉积盖层中的层滑倾滑和推覆滑覆等各种构造的形成机制，对该区沉积盖层进行了较系统的岩石物性和岩石力学标本采集和测试（包括三轴参照实验）．依其参数结构特点和地质、物探资料，划分出４套７层区域性层滑系统，并与研究程度较高的中、下扬子区的物性参数、岩性组合和构造特征进行综合对比．最后还进一步阐明了塔里木北部地区特征的前列式冲断构造和含油气局部构造等，均受到这７层区域层滑系统的制约．

| Abstract: | In order to study quantitatively the regional layered structure and detachment structure ,expecially for the mechanism of various structures about the layerslip-dipslip and nappe-sliding in the sedimentary covering strata concerning the oil-gas geology trap structure, physico-mechanical samples of rocks have been systematically selected and determined in the northern Tarim area(including a consultant test of friaxial compression). Likewise based on parametric texture characteristics and observation data of geology and geophysical exploration, three suits and seven layers of the regional layerslip systems were subdivided, and the physico-mechanical parameter and lithologic composition as well as structural character were synthetically compared with the Middle-Lower Yangtze area in which the research degree is higher. Finally characteristic forward thrust structures and oil-gas bearing local structures which were controlled with the seven layers of regional layerslip systems were progressively explaned in the northern Tarim area as well. |
