There are two kinds of oil supply ways in the Tertiary clastic rock oil reservoirs in Jizhong Region:one is fractured surface supply oil;the other is bedded permeable layer supply oil.Oil diverting faults did not only control trap formation and reservoir distribution

but also controlled the migration paths.The bedded permeable layer supply oil is controlled by structural hights

the migration paths are usually the counter lines of vertical structures

and oil migrates towards the height of noze structure along the noze bridg.The traps along oil and gas migration paths are favourable for hydrocarbon pool formation.It thus suggested that the middle and the lower parts close to oil diverting fault and the bridge of the noze structure are most favourable for future rolling exploration.
