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．
The Wenxi Depression is a faulted basin developed from the background of the Luxi Uplift. During the early Tertiary period, the faults in the northern boundary of the depression have been strongly active for many times. They not only control the formation and evolution of fault structures in different periods within the depression, but also control the type and distribution of sedimentary facies belt. In order to reveal the inner relationship between Tertiary tectonic evolution and sedimentary facies distribution in the depression, combining the study of outcrops and coverage areas, the study on the tectonics and sedimentation of the depression has been carried out by comprehensively using the geologic, seismic and well logging data. The tectonic facies model provides the basis for oil and gas exploration in Wenxi depression.
