摘要：
油水分离器分离性能随着油田来液含水率逐年升高而不断下降，为提升分离器油水分离效率，基于fluent软件采用realizable k-ε模型和mixture多相流模型对重力油水分离器内部流场进行三维数值模拟，以整流效果较好的田字板型整流构件为研究对象，引入正交试验，以分离器油出口含水率为试验指标，进行构件开孔方式、构件长度以及构件安装位置三种因素对油水分离效率的影响分析。研究表明，对于田字板型整流构件，开孔方式对其分离效率影响最大，构件长度次之，构件安装位置影响最小，且当开孔方式为“上疏下密”型，板长2000 mm，安装在入口构件后800 mm时，分离器油出口含水率由26.90%降低至16.73%。该研究成果可为分离器整流构件设计提供技术参考。

abstract: as the water content of incoming liquid increases year by year, the separation performance of oil-water separator decreases continuously. the realizable k-ε model and the mixture multiphase flow model are used to perform three-dimensional numerical simulation of the internal flow field of the gravity oil-water separator based on the fluent. the tian-type rectifier components with better rectification effect is taken as the research object and the orthogonal test is introduced. water content of the separator’s oil outlet is taken as the test index to analyze the influence of three factors on the oil-water separation efficiency, namely the opening mode of the component, the length of the component and the installation position of the component. the results show that the opening mode has the greatest influence on the separation efficiency, followed by the length of the component and the installation position of the component. and when the opening mode is sparse at the top and serried at the bottom, the plate length is 2000 mm, which is installed 800 mm behind the inlet component, the water content decreases from 26.90% to 16.73%. this research can provide technical reference for the design of separator rectifier components.
