摘　　要：油田开发中油气水三相流共存是普遍存在的现象,由于气相的干扰,使原有测量两相流的仪器不能满足多相流测量精度的要求。为了解决油井井下油气水三相流流量测量精度低的问题,设计了低产液高含水条件下,井下气液分离装置的物理模型。在此基础上,构建了气液分离装置模型。利用Fluent模拟仿真软件对模型进行数值模拟,得到20~60m^3/d流量下气液分离的效率,仿真结果显示该模型气液分离效率高,具有很高的可行性。设计的气液分离装置为整体实验样机设计制作奠定了理论基础。The coexistence of oil,gas and water three-phase flow is a common phenomenon in oilfield development.Due to the interference of gas phase,the original instrument for measuring two-phase flow can not meet the requirements of accurate measurement of multi-phase flows.In order to solve the problem of the low accuracy in flow measurement of oil-gas-water three-phase flow in well,the physical model of the downhole gas-liquid separation device is designed under the condition of low production and high water cut.On this basis,the gas-liquid separation device model is constructed.FLUENT simulation software is used to simulate the model numerically and the efficiency of gas-liquid separation at 20~60 m^3/d flow rates is obtained.The simulation results show that the gas-liquid separation of the model is efficient and it has high feasibility.The designed gas-liquid separation device has laid a theoretical foundation for the design and manufacture of the whole experimental prototype.
