摘　　要：对于采液指数较高的油井,水平管路压降预测准确与否,将会显著地影响油井产量的预测结果。结合生产实际,在多相管流实验平台的基础上,设计并建造了水平管路变质量流动实验系统,针对水平管路变质量流动规律进行了气液两相变质量流动实验研究,并拟合得到符合实际流动特征的阻力系数计算新方法。实验结果表明:通过拟合无滑脱气液两相流阻力系数与两相流动雷诺数得到的拟合公式,能够用于水平有入流管路多相管流的压降预测;气液比较大时,侧流对压降没有明显的影响;气液比较小时,侧流存在会增大压降。For oil wells with high liquid production index, the prediction of pressure drop in horizontal pipeline is accurate or not, which will significantly affect the prediction results of oil well production. Combined with the actual production in multiphase pipe flow experiment platform based on, the design and construction of the horizontal pipeline flow experimental system of variable mass,for horizontal pipeline flow pattern of the experimental study on quality of gas liquid two phase flow,and fitting with the drag coefficient of the actual flow characteristics,a new method for the calculation.The results show that by fitting the no slip gas-liquid two-phase flow formula of resistance coefficient and flow Reynolds number,can be used for horizontal inflow pipeline multiphase pipe flow pressure drop prediction;the liquid is relatively large,lateral flow effects on the pressure drop is not visible;liquid is relatively small,side stream will increase the pressure drop.
