摘　　要：天然裂缝性低渗透砂岩油藏开发潜力巨大,进行相关数值模拟研究对于保证油田高产稳产具有重要的意义。为实现天然裂缝性低渗透油藏的快速数值模拟研究工作,以反九点井网为例建立概念模型,运用流管法结合等效连续介质模型进行数值模拟研究,绘制渗流模板,建立适合天然裂缝性低渗透砂岩油藏的数值模拟研究方法。将流管法应用于实际区块开展数值模拟研究,与常用软件模拟结果对比,发现流管法结合等效连续介质模型适用于天然裂缝性低渗透油藏的数值模拟研究工作。With great potential to develop and guarantee oilfield production,numerical simulation on naturally fractured low-permeabil-ity reservoirs is of great importance.In order to achieve fast numerical simulation which is suitable for naturally fractured low-permea-bility reservoirs,a nine-spot pattern conceptual model is established,stream-tube method combined with equivalent continuous medium model is applied to the fractured low-permeability,and template is drawn.Numerical simulation research method is established for frac-tured low-permeability reservoir.Stream-tube method is applied in an actual oilfield,which is compared with commonly used software. The results show that stream-tube method combined with equivalent continuous medium model can be used for the simulation of the fractured low-permeability reservoir.
