摘　　要：对研究区葡萄花油层源-圈空间配置、油运移输导形式和对成藏与分布的控制作用研究可知:葡萄花油层源-圈空间配置有源下圈正上方和源下圈侧上方2种配置关系,油运移输导形式有直线型、反"L"型和"U"型3种形式,直线型运移输导形式由过T2—T06断裂构成;反"L"型运移输导形式由过T2—T06断裂和过T1—T06断裂沟通砂体构成;"U"型运移输导形式由过T2—T06断裂、被T2—T06断裂沟通砂体和过T2—T06断裂构成。3种运移输导形式对油成藏与分布的控制作用主要表现为:①过T2—T06断裂控制着源下圈正上方空间配置油藏的形成与分布;②过T2—T06断裂越发育,源下圈侧上方空间配置油供给越充足;③源下圈侧上方空间配置反"L"型运移输导形成的油藏均分布在过T1—T06断裂沟通砂体输导通道上或附近;④源下圈侧上方空间配置"U"型运移输导形成的油藏均分布在过T2—T06断裂附近。Based on the research on source-trap space allocation, oil migration transporting form and there controlling effects on reservoir formation and distribution in Putaohua oil layer in and around Sanzhao Depression, it is considered that there are two kinds of source-trap allocation relations in Putaohua oil layer in and around Sanzhao Depression： source rock bottom-trap top and source rock bottom-trap lateral top. And there are 3 kinds of oil migration transporting forms： linear type, reverse ＂L＂ type and ＂U＂ type. Linear migration transporting form is composed of source faults which pass through T2-T06 reflection layers. Reverse ＂L＂ type migration transporting form is composed of source faults which pass through T2-T06 reflection layers and sand bodies connected by faults which pass through T2-T06 reflection layers. ＂U＂ type migration transporting form is composed of source faults which pass through T2-T06 reflection layers, sand bodies connected by faults which pass through T2-T06 reflection layers and faults which pass through T2-T06 reflection layers. The controlling effects of these 3 kinds of migration transporting forms in oil accumulation and distribution are showed as follows： （1）Source faults which pass through T2-T06 reflection layers control the formation and distribution of reservoir which belongs to source rock bottom-trap top space allocation; （2）The better source faults which pass through T2-T06 reflection layers developed, the more sufficient oil supply which belongs to source rock bottom-trap lateral top space allocation was; （3）Reservoirs which was formed by source rock bottom-trap lateral top space allocation reverse ＂L＂ type migration transporting forms all distribute in or near sand body transporting pathway connected by faults which pass through T1-T06 reflection layers; （4）Reservoirs which was formed by source rock bottom-trap lateral top space allocation ＂U＂ type migration transporting forms all distribute near faults which pass through T2-T06 r
