摘　　要：濮城 Es2 段油藏为复杂断块油藏 ,进入高含水开发期后 ,油藏产量递减大 ,含水上升快 ,注采系统适应性差。应用测井资料、油层平面非均质性分析、沉积相分析、数值模拟及测井沉积微相法 ,对该油藏剩余油分布规律及开采方法展开研究 ,剩余油挖潜措施实施后 ,增油效果十分明显。Es 2 reservoir is a complicated fault block oil reservoir After entering into the high water cut stage,oil production decreases,and water cut increases rapidly,thus adaptability is poor in injection production system By using the well logging data,analyzing the reservoir plane heterogeneity and sedimentary facies,numerical simulation as well as logging sedimentary microfacies, a study is carried out on the rules and methods of remaining oil distribution After the stimulation of potential production is implemented,oil production enhancement is obvious The result demonstrates that it could be used for the development of similar oil reservoirs
