Abstract:Shangjia region is a nose structure. It is located outside of the oil area of K1qn1(1st Member, Qingshankou Formation, Lower Cretaceous) in the Sanzhao sag, Songliao Basin. In this region oil accumulation and distribution are controlled by transporting pathway. Transporting pathways of oil and its controlling to oil accumulation and distribution in the region can or not be recognized, it is of important significance to point oil exploration and to abundance oil—gas accumulation theory. Using the method of oil source correlation, typical oil reservoirs anatomy and oil accumulation models, oil transporting process in Shangjia region was studied. It is classified into 3 parts:T2 faults connecting sourcerock were transporting pathways for migration downward of oil from K1qn1 source rocks into Fuyu, Yangdachengzi oil layers in Sanzhao sag. Sand bodies connecting by T2—T2-2 faults were transporting pathways for oil in Fuyu, Yangdachengzi oil layers migrating laterally from Sanzhao sag to Shangjia region. T2—T1-1 faults were transporting pathways for oil in Fuyu, Yangdachengzi oil layer migrating to Putaohua oil layers in Shangjia region . Using the method studying the relation between oil transporting pathways and oil distribution, controlling of transporting pathways to oil accumulation and distribution was studied, it was concluded that the more developed the faults were, the more sufficient the oil source for lateral migration from Sanzhao sag to Shangjia region was. The position and ability of transporting pathways which were sand bodies connected by T2—T1-1 faults controlled the distribution and abundant degree of oil in Fuyu, Yangdachengzi oil layers and K1q2. The distribution of T2—T1-1 faults transporting pathways controlled the abundant area of Putaohua oil layers in Shangjia area.
