P108 Block Residual Fine Potential In Research

The depositional environment of the 108 block is the delta front facies sedimentary facies.The distribution of the sand bodies on the plane is dominated by the microfacies sandbody in the underwater distributary,mainly in the north-south stripes.After the high water cut period,the distribution of the remaining oil in the 108 block is complicated and scattered,which restricts the oilfield development effect.Therefore,revealing the distribution of remaining oil,clearing the relationship between remaining oil reserves,spatial distribution characteristics,geological factors and injection and production conditions is further clarified,which is the prerequisite and basis for tapping the remaining oil,improving oil displacement efficiency and crude oil recovery.Based on the geological modeling of the Portuguese block 108 and the comprehensive utilization of geology,logging,earthquake and production dynamic data,this paper carried out the study on the geological features of the 108 block,the microstructure and the fine reservoir description,The Plane Distribution Characteristics of River Sandbody.On the basis of this,the dynamic monitoring data and the numerical simulation are used to study the distribution of residual oil,clarify the distribution characteristics of different types of residual oil,put forward the effective control and control measures to improve the water flooding,achieving the purpose of improving the water drive to spread the volume and improving the water flooding situation.Through the use of reservoir fine numerical simulation technology,the remaining oil formation and distribution of comprehensive description of technology and forecasting,including a number of matching methods and techniques,we improve the narrow sandstone oil field remaining oil tapping potential treatment program,the method provides us a way to solve the same high water period Oilfield residual oil and it has a wide range of applicability.
