| 摘 要： | 塔北隆起是塔里木盆地的主要含油气区,笔者利用地震剖面解释和平衡剖面技术对塔北隆起构造变形和构造演化进行了研究.塔北隆起构造变形存在明显的构造差异,西部英买力地区主要发育盖层滑脱式逆冲断层褶皱和"y"型压扭断层,而其东部主要发育基底卷入式逆断层及断层传播褶皱和反冲断层构造.造成塔北隆起东、西构造样式差异的机理主要有两点:一是东部地区对震旦纪一早奥陶世正断层在后期挤压作用下反转,二是英买力地区中寒武统盐层的发育.塔北隆起地区古生代构造演化也存在着一定的差异,塔北隆起东部震旦纪一早奥陶世发育大型正断层构造,而英买力地区为稳定碳酸盐岩台地;晚奥陶世至泥盆纪,塔北隆起东部牙哈断层发生反转,轮台凸起隆升,而英买力地区位于隆起的斜坡部位;石炭纪至二叠纪,塔北隆起东部大规模抬升,剥蚀严重,出露变质基底,英买力地区接受强烈的变形作用,主要发育盖层滑脱式逆断层和褶皱构造.

| Abstract: | The North Tarim Uplift is one of the most important oil and gas-bearing areas in the Tarim Basin. Seismic section and balanced section were used to reveal its structural styles and evolution. The structural styles in the North Tarim Uplift are remarkably different in its different parts. Yingmaili in the west of the North Tarim Uplift mainly has decollement folds and faults and 'y'-style transpressure faults,while the east of the North Tarim Uplift has well-developed basement-involved faults,fault-propagate... |
