前陆盆地的基本结构和主要单元的位置在不同演化阶段是变化的,通常情况下前陆盆地的规模及其油气性也是千差万别,我国中西部造山带边缘的盆地结构中,总体上前陆盆地的变形和沉积特征明显,具有前陆盆地的典型特征。针对我国中西部前陆盆地的特征及演化过程,对其油气性进行了分析。 The basic structure of the foreland basin and the location of major units vary in different evolution stages. Generally, the size and oil and gas of the foreland basin vary widely. In the basin structure at the edge of the orogenic belt in central and western China, generally, the foreland basin Deformation and sedimentary characteristics of the obvious, with the foreland basin typical features. In view of the characteristics and evolution of the foreland basins in central and western China, the oil and gas properties were analyzed.
