摘要(Abstract)：

地壳浅表存在不同形式和结构的底辟,膏盐底辟和泥岩底辟的生长导致上覆层系发生构造变形、破裂,常伴随油气等流体运移形成不同类型的油气藏或矿藏而备受关注。主要基于以自然底辟相关构造为研究对象的砂箱物理模型研究结果,系统阐述了地壳浅表底辟构造"实验-实例"互证相似性机理,综述了砂箱物理模型模拟所揭示的底辟构造形成过程与特征,并以巴西Santos和中国南海莺歌海含油气盆地底辟构造为例对比探讨了砂箱模型实验的可行性。通过"实验-实例"间具相似流变学特征的砂箱物理模拟研究,揭示出底辟形态与其成熟度、围岩与底辟物质黏度有关,被动底辟构造形态受控于底辟上升速率与沉积加积速率相对比值;底辟构造平面上具典型环带结构,其内部结构的复杂程度随构造走向或倾向发生变化,伴随底辟上升和侵位,其围岩发育各类伴生构造;膏盐底辟和泥岩底辟的物质流动特性、驱动机制及流动单元的差异导致其底辟形态、构造样式、地貌特征明显不同;底辟构造形成演化的主控因素是与重力、侧向应力及热作用相关的差异载荷作用,而浮力为次要因素,同时基底盐层起伏及地形坡度对盐流和盐上变形模式具有一定的影响。砂箱物理模拟能为底辟构造运动学和内部结构的解释提供较好的模型,能够有效再现从拉张被动大陆边缘体系到挤压褶皱冲断带-前陆盆地体系中底辟构造形成演化的四维过程,在与膏盐、泥岩(流体)底辟构造相关的深层、深水油气勘探中将发挥越来越重要的作用。
