摘　　要：利用油藏渗流模型和水平井筒内的流动模型,推导出了油藏/井筒耦合模型。该模型同时考虑了两种流动的相互作用和影响。建立了以水平井生产端压差为目标函数、以孔眼分布为决策变量的优化模型,同时和均匀流入剖面、均匀射孔分布的结果进行了对比。优化模型考虑了水平井筒内变质量流的影响,可为现场水平井的优化设计提供理论基础。The coupling model of resevoir/wellbore is deduced from resevoir flow and horizontal wellbore flow model. The inter＆ction and influence between two flows are considered in the present model. The optimization model which the horizontal well drawdown is regarded as objection function and the perforation distribution as decision variable is presented. The comparison of the present model with the results of a uniform-influx and a uniform perforation distribution is made. The effect of variable mass flow is considered in the optimization model. The theoretical basis of the optimization design for horizontal wells is provided.
