摘　　要：通过对微元井段压降的分析,考虑了壁面入流的影响,那么根据质量守恒,动量守恒定理可以推导变质量流动模型。由于油气水三相变质量流动分散流的混合程度均匀,因此在研究的时候将分散流看成了一种黏度比较复杂的均质液体。考虑到存在壁面入流对射孔井段分散流压降的影响,得到水平射孔井段油气水三相变质量流动分散流的压降计算方法。Through the analysis of the differential element wellbore pressure drop,considering the influence of wall inflow,according to the mass conservation and momentum conservation theorem,variable mass flow model was derived.Due to evenly dispersed mixing degree of the oil-gas-water three-phase variable mass flow,the dispersed flow was taken as a homogeneous liquid with more complex viscosity in the research.Considering the influence of wall inflow on the dispersed flow pressure drop,the calculation method for the dispersed flow pressure drop of oil-gas-water three-phase variable mass flow in horizontal well perforation section was obtained.
