Through oil reservoir anatomization and analyzing its spatial-temporal relationgship with reservoir forming condition, migration and the control on oil accumulation and distribution were studied on the basis of the summarizing oil migration mechanism and mode in Shuixigouqun oil layer,Qiquanhu structural belt. It was considered that oil migration pathways of Shuixigouqun oil layer of Qiquanhu structural belt were as follows in main:One is that the Yanshan stage faults are transporting pathways through which oil that generated by Shengbei depression coal source rock of Shuixigouqun migrated upward into Xishanyao zu and Sanjianfang zu oil layers. The second is that the sand bodies combining with faults are transporting pathways of oil in Shuixigouqun oil layers in Shengbei depression migrating laterally to Shuixigouqun oil layer in Qiquanhu structural belt.The controlling roles of oil migration pathways of Shuixi- gouqun oil layer in Qiquanhu structural belt to oil accumulation and distribution are mainly manifested as: One is that the development degree of Yanshan stage faults controls oil supply amount of Shuixigouqun oil layer in Qiquanhu structural belt. The second is that the exhibition characteristic of Shuixigouqun oil layers sand bodies in Qiquanhu structural belt are main oil accumulation areas,and high structural position of high fault block connected by transporting pathways that formed by sand bodies combing with faults are mian oil accu- mulation areas.Form the above comprehensive study,the reservoir with in the high fault block should be the favorable objects oil exploration.
