摘　　要：裂缝性油气藏在油气资源中的占比不断增加,由于储层裂缝系统定量描述的复杂性,裂缝性油气藏开发动态的准确模拟预测一直是研究的难点。本文系统地介绍了裂缝性油气藏的模拟模型,包括描述天然裂缝系统的等效连续介质模型和双重或多重介质模型,以及描述压裂裂缝的离散裂缝模型和嵌入式离散裂缝模型。历史拟合是利用实测数据调整模型参数达到提高模型模拟预测水平的重要技术。基于梯度类方法、进化算法、人工神经网络、集合卡尔曼滤波算法等自动历史拟合方法,在油藏开发实践中得到广泛应用。微震数据能够提供压裂裂缝分布的重要信息,在自动历史拟合的过程中,可以和生产数据共同约束模型参数的多解性。Fractured reservoirs are becoming increasingly important in reservoir engineering.However,due to the complexities of the fracture systems,it is difficult to predict well performance in fractured reservoirs.The dominant numerical models to deal with fractured reservoirs are introduced.These include the equivalent continuum model,the dual media model,the discrete fracture model and the embedded discrete fracture model.History matching is an essential process to improve the model predictability by using production data.A variety of automatic history matching methods have been developed,such as the gradient-based method,the evolutionary algorithm,the artificial neural network method and the ensemble Kalman filter method.Microseismic data can provide useful information to constrain modeling of the hydraulic fracture distribution,and can be used jointly with production data to improve the model prediction.
