Abstract: The configuration of source rocks and transportation system can be divided into three types of vertical contact,lateral contact and staggered contact according to their contact relationship,and can also be divided into three types of source rocks-fault,source rocks-connected sand bodies and source rocks-unconformity according to different hydrocarbon migration system. The control factors forming different combination and important effects on configuration rule of hydrocarbon source rock and transportation system were summarized.In different configuration combination,there are some difference on hydrocarbon migration fashion,migration efficiency and forming-pool types,which made different characteristic of spacial distribution of oil and gas.The configuration between source rock and fault controlled vertically dominant petroleum migration in central up-lift belt of the Linnan Sag,the Jiyang Depression of the Bohawan Basin.The configuration between source rock and connected sand bodies controlled laterally dominant petroleum migration in the Xiakou fault zone of the Jiyang Depression.
