摘　　要：根据水平井筒内单相变质量流特点 ,考虑影响井筒压降大小的各个因素 ,利用质量守恒定律、动量定理以及管流摩阻公式 ,建立了水平井筒压降计算模型。把井筒压降计算模型与油藏三维渗流模型耦合起来 ,可以得到井筒中的压力分布。通过对分支水平井井筒压力的初步研究 ,建立了井筒压力分布求解模型 ,得出了一些有益的结论 。Due to the characters of single phase and various mass rate flow in the horizontal wellbore, and on the basis of the principle of mass conservation,momentum theorem and frictional resistance formula in the pipeline flow, the calculating models of pressure drop in the horizontal wellbore are derived. The influence factors of pressure drop in the wellbore are also considered. Coupling the calculating models of wellbore pressure drop with the 3D steady state flow in the reservoir, the pressure distribution can be obtained. Through the preliminary research on the pressure distribution in the wellbore of multilateral horizontal wells, the calculating models of pressure distribution are established and some beneficial conclusions are acquired, which establishes a good base for future research.
