以胜利油区某潜山油藏为例 ,考虑底水和边水 ,建立单井模型。利用数值模拟技术研究了具有边底水的双重介质油藏开发过程中油水运移规律 ;分析了基质渗透率、裂缝渗透率、裂缝密度、采油速度、打开程度等地质、工艺方面的参数对出水规律的影响 ,得到裂缝型潜山油藏含水上升主要特征 ;根据油藏地质特征、开采参数和含水率变化规律归纳得出边底水入侵的基本模式 ,为配置控水措施、改善双重介质油藏的开发效果提供了理论依据。
Taking a buried hill reservoir in Shengli oilfield as an example, single-well model was established considering bottom water and edge water. The law of oil and water transport during the development of a dual medium reservoir with edge water was studied by numerical simulation. The effects of geological and technological parameters such as matrix permeability, fracture permeability, fracture density, oil recovery rate, The main characteristics of water cut in buried hill reservoirs are obtained. Based on the reservoir geological characteristics, the mining parameters and the variation rule of water cut, the basic pattern of edge water intrusion is concluded. In order to dispose water control measures and improve the dual medium reservoir The development of results provide a theoretical basis.
