摘　　要：本文应用地质、地震、非地震、钻井等资料,结合前人研究成果,对中国中西部前陆盆地进行了综合研究,认为中西部前陆盆地为复合、叠合盆地,具有双层结构模式,盆地的结构存在较大差异,盆地内塑性岩层对构造变形具有重要的调节作用,各前陆盆地均存在一组与盆地走向近于垂直的断裂构造,对盆地的变形特点、油气的分布具有重要控制作用。前陆盆地烃源岩发育,构造成排成带,是有利的油气勘探区,构造带与烃源岩的位置关系决定了油气勘探的潜力。Foreland basins in the central-western China are researched comprehensively with the geology, seismic, non-seismic and drilling data. The result is that the foreland basins in central-western China are composite and superposed basins and have double deck framework. The configuration of basins is different respectively. The ductile strata of the basins play important adjusting roles in structural deformation. There exist a group of faults intersected with the basins extension at right angles. These faults play important controlling role in basin deformation and oil and gas distribution. The foreland basins develop source rocks, have groups of structure belts and are advantageous areas for oil and gas prospecting. The ubiety of structures and source rocks affects the potential of oil and gas exploration.
