摘　　要：汶西凹陷是鲁西隆起背景上发育而成的断陷盆地．凹陷北界断裂在早第三纪期间多次强烈活动，不仅控制了凹陷内不同时期断裂构造的形成和演化，而且控制了沉积相带的类型和分布．为了揭示凹陷内下第三纪构造演化与沉积相带分布的内在联系，将露头区与覆盖区研究相结合，综合应用地质、地震和测井资料，开展了凹陷的构造和沉积研究，建立了构造岩相模式，为汶西凹陷油气勘探提供了依据．Wenxi depression was a rift subsidence basin developed on Luxi uplift. The northern boundary fault of the depression repeatedly and strongly rifted in Eogene controlled not only formation and evolution of different stage faults, but also types and distribution of sedimentary facies during Eogene in the depression. In order to reveal interior relation between tectonic evolution and distribution of sedimentary facies of Eogene in the depression, the studies of outcrop area and cover area were combined. Geological, seismic and log data were comprehensively used to research fault features and sedimentary facies of the depression. Finally,tectonic lithofacies model was developed. This study provided a scientific basis for oil exploration in the depression.
