三塘湖盆地是一个长期处在挤压应力环境下的中小型叠合型盆地，盆地南北两侧长期大规模的逆冲推覆造就了两隆夹一坳的构造格局。盆地中部坳陷区以压扭性构造为主要特征，并受断裂影响形成三个变形带及一系列次级构造单元，这些构造单元控制着油气的聚集与分布。
The Santanghu Basin is a medium-sized and small-scale superimposed basin long-term under compressive stress. The long-term large-scale thrust-nappe on the both sides of the basin has created the structural pattern of the two cliques. The central depression in the basin is characterized by compressive-toothed structure. Three deformation zones and a series of secondary structural units are formed due to the fracture. These structural units control the accumulation and distribution of oil and gas.
