摘　　要：在段永刚等人提出的井筒与油藏耦合作用下的水平井产能预测数学模型的基础上 ,借鉴H .Cinco等人求解有限导流垂直裂缝压裂井压力动态的计算方法 ,建立了井筒与油藏耦合作用下底水驱油藏水平井非稳态产能预测模型 (其中 ,油藏模型为底水驱无限大油藏 ,井筒模型中考虑了流体摩阻、动量变化、井筒壁面流入的混合干扰等因素的影响 ) ,对该模型进行迭代求解可以获得定产量条件下井筒流率分布、井筒压降分布等重要信息。Based on the productivity prediction model of horizontal wells under a wellbore and reservoir coupling proposed by Duan Yonggang et al and the method to calculate transient pressure of wells with finite conductivity vertical fractures proposed by H. Cinco et al, a transient productivity prediction model of bottom-water drive reservoir is developed for horizontal wells under a coupling of wellbore with reservoir, in which the reservoir model is an infinite reservoir with bottom-water drive and the wellbore model has considered the factors such as liquid friction, momentum changes and well wall inflow. Using an iterative method to resolve the model, we can obtain many important information under a constant production, such as inflow flux and pressure drop in wellbore.
