摘　　要：针对濮城油田东区沙二下多层砂岩断块油藏特点 ,通过细分流动单元、沉积微相和储层参数研究 ,应用三维可视化建模技术和随机建模技术 ,建立了油藏三维地质模型和储层随机模型 ,对剩余油监测解释技术、剩余油挖潜的调堵和调驱配套技术进行研究。并通过对油藏剩余油定性和定量以及大规模油藏数值模拟综合研究 ,弄清了剩余油的分布规律。在此基础上制定剩余油调整挖潜、降水稳油、增加可采储量措施 。According to the characteristic of the block reservoir in Sa 2 lower multi layer sandstone in the east of Pucheng Oil Field,this paper constructs a 3D geologic model and reservoiu random model through subdividing flow units,sedimentary micro phase and reservoiu parameter study and using 3D visualization modeling technique and random modeling technique.It also studies residual oil monitoring interpretation technique and the matchin technique of plugging controland displacement control of residual oil potential seeking.Through the qualification and quantification on reservoir residual oil and a large amount of reservoir numerical simulation study,it recognizes the distribution rule of the residual oil.Finally,it determines the measure of residual oil adjustment potential seeking,reducint water cut and stabilizing oil product and improving the recoverable reserves.
