摘要(Abstract)：

利用相渗曲线法、物质平衡法、递减法对南堡2号潜山碳酸盐岩油藏开发效果进行评价,研究和探讨了南堡2号潜山油藏开发中存在的问题,分析了12口水平井生产特征,揭示了双重介质油藏油水运动规律,落实了剩余油分布规律。研究结果表明:油井生产效果受构造和储层双重因素控制;油藏初期含水上升规律与裂缝系统吻合较好,目前仍偏向于裂缝系统的理论含水上升规律;天然水侵驱动指数大,对油藏开发起主要作用;油藏递减率大,开发效果变差;油藏存在五种宏观剩余油分布模式和六种微观剩余油分布模式。
With the help of relative permeability curve method,material balance method and regressive method,the developed effects of Nanpu 2 buried hill carbonate oil reservoirs were evaluated; the existing problems in the process of the reservoir development were discussed and studied,the production characteristics of 12 horizontal wells were analyzed,the oil-water moving laws of the dual-media reservoirs were revealed,thus the distributing rules of the remained oil were implemented. The achievements indicate that the production effects of the oil wells are controlled by the dual factors of the structures and reservoirs; the watercut rise laws of the reservoirs accord with the fracture system in the early,and furthermore at present the laws still prefer to accord with the theoretical watercut rise regulations of the fracture system; natural water invasion driving index is large and plays a major role in the development of the reservoirs; reservoir decline rate is large,the developed effects become poor; there are five kinds of macro remained oil distributing patterns and six types of micro remained oil distributing patterns in the reservoirs.
