摘　　要：通过对济阳坳陷油气输导体系的综合研究,认为不同类型、不同规模断陷湖盆发育的输导体系存在明显的差异:①在箕状湖盆中并非某种单一输导要素起主导作用,输导特征总体表现为复式输导,而在双断式湖盆中,断裂在输导体系中起主导作用,输导要素单一,输导特征总体表现为单一输导;②在小型箕状断陷湖盆中,物源简单,断裂和砂体主要成阶梯型组合,输导特征表现为以阶梯型为主的简单复式输导,而对于大型宽缓箕状断陷湖盆,物源复杂,输导特征总体表现为多源复式输导.Through the comprehensive study of passage systems in Jiyang Depression,it is held that there is obvious difference in the passage systems developed in different types and sizes of faulted lake basins:(1) in halfgraben-like lake basins,there are several essential passage elements;while in double-faulted lake basins,faults play an important role in the passage systems.(2) In small-size halfgraben-like lake basins,hydrocarbon source is simple,the passage systems are characterized mainly by ladder-type complex hydrocarbon conduction;while in large-size wide-shallow halfgraben-like lake basins,hydrocarbon source is complex,the passage systems are characterized mainly by multi-source complex hydrocarbon conduction.
