摘　　要：由于人工经验选取的局限性,难以获取决定模型重构精度的最优网络参数是目前使用深度学习方法在自动历史拟合中对油藏地质模型进行降维时的难点之一。针对此问题,通过将深度自编码器与粒子群优化算法相互结合实现最佳网络架构的自动搜索,并以此构建一种基于集合数据同化和神经网络架构自动搜索的油藏自动历史拟合方法。分别对一个二维河流相油藏渗透率场分布模型以及SPE-10单层油藏数值模型应用该方法,并与单一的自动历史拟合方法进行对比验证。结果表明,经优化后自动搜索出最优神经网络构架的自动历史拟合方法要比优化前及单一的自动历史拟合方法能够更准确地提取出油藏数值模型的地质特征。Due to the limitations of manual selection via human experience,it is difficult to obtain the optimal network parameters that determine the accuracy of model reconstruction,which is currently one of the difficulties when using deep learning methods to reduce the dimensionality of reservoir geological models in automatic history matching.In response to this,the automatic search of the best network architecture was realized by combining the deep auto-encoder and the particle swarm optimization algorithm,and an automatic reservoir history matching method was constructed,based on aggregate data assimilation and automatic search of the neural network architecture.A two-dimensional permeability distribution model of a fluvial reservoir and a SPE-10 single-layer reservoir numerical model were used to verify the proposed method,in comparison with a single automatic history matching method.The results show that the automatic history matching method can automatically searches the optimal neural network framework after optimization,which can extract the geological characteristics from the reservoir numerical model more accurately than the single automatic history matching method.
