摘要: 形成裂缝网络的裂缝性油气藏可用Kazemi模型、WarrenRoot模型和De Swaan模型进行描述,而没有形成裂缝网络的局部裂缝发育油藏就不适合应用这3种模型。针对低渗透油藏存在的局部裂缝特征,利用平行板理论、张量原理和等值渗流阻力原理,建立了裂缝区的等效连续介质模型,在等效连续介质模型的基础上,建立了低渗透油藏三维数值模型,并用黒油模拟程序进行实例计算。研究结果表明:等效连续介质模型可以应用到具有局部裂缝的低渗透油藏数值模拟和动态预测中。

Abstract: The fractured reservoirs with fracture network can be described with Kazemi model,Warren-Root model and De Swaan model,but the three models are not suitable for the reservoirs with locally developed fractures and without fracture network.Aiming at the feature that there exist local fractures in low permeable reservoir,by means of parallel-plane theory,tensor principle and equivalent flow resistance principle,the equivalent continuum media model of fracture-developed area is set up,on the basis of the model,3-D numerical simulation model for low permeability reservoir is established,and the black oil modeling program is used to conduct case study.Consequence shows that the equivalent media model can be applied to numerical simulation and dynamic prediction for the low permeability reservoir with local fractures.

Key words: fractured reservoir, low permeability, equivalent continuum media model, adaptability, numerical simulation
