摘　　要：油水两相混合流动是石油开采过程中的常见现象,对其流动规律进行探究有着重要的科学价值和工程应用价值。应用GAMBIT软件,建立集流管道长度为600mm、测量管道长度为1 000mm的仿真模型,并根据建立的模型完成网格划分。应用Fluent软件,对划分好的网格在不同油水配比率条件下进行相关数据的数值模拟计算,对其数值模拟结果进行Fluent软件的后处理,并将数值模拟计算结果进行可视化处理。根据Fluent软件后处理得到的数据和图像结果可知,流体在水平管流低流量集流条件下达到流型稳定状态所需要的时间,随着流体含水率值的减小而减小,且达到稳定状态所需要的入口距离至少为20cm。The oil-water two-phase mixture flow is common phenomenon in the process of oil production, and exploring the flow pattern has important scientific value and engineering application value. Use GAMBIT software to build the simula tion model which has a current collecting pipe length 600 mm and a measurement pipeline length 1 000 mm, and it is accord ing the established model to mesh. Then the Fluent software is used to simulation calculation the grid at the different oil wa- ter ratio, and postprocess the results used by Fluent software. Then visualize the results of numerical simulatio, according to the results of the Fluent software to get the results of the data and images of postprocessing. The low flow concentration needs to reach the steady state flow time decreases with the decrease of moisture content values in the fluid level, and rea ches the entrance to the steady state distance of at least 20 cm.
