%X 随着油气井开采不断发展，无杆采油泵由于其克服了传统采油泵产生偏磨等问题而受到广泛的研究与重视，目前对无杆采油泵效率的提升是首要任务。为此，本文采用某公司研发的一款全自动换向无杆采油泵为研究对象，结合本产品实验条件，运用田口实验设计和计算流体动力学数值模拟方法对无杆采油泵迷宫密封内部流场进行研究和优化。结果表明：在密封间隙为0.13 mm，密封槽深度为0.7 mm，密封槽的数量为6个，密封口两端压差为13 MPa，迷宫密封性能最优；并且与原产品实验相比，各因素优化组合后，其密封效果提升27%。所得出的结论可以为采油泵中迷宫密封的设计与应用提供借鉴和参考。
With the development of oil and gas well exploitation, rodless production pump has been widely studied and paid attention to because it overcomes the problems of traditional production pump. Therefore, it is the primary task to improve the efficiency of rodless oil pump. Therefore, a fully automatic reversing rodless oil pump developed by a certain company is adopted as the research object in this paper. Combined with the experimental conditions of this product, the internal flow field of rodless oil pump labyrinth seal is studied and optimized by Taguchi experiment design and computational fluid dynamics numerical simulation method. The results show that when the sealing gap is 0.13 mm, the sealing groove depth is 0.7 mm, the number of sealing slots is 6, and the pressure difference between the two ends of the sealing port is 13 MPa, the labyrinth sealing performance is the best. And compared with the experiment of the original product, the sealing effect is improved by 27% after the optimization of various factors. The conclusion can provide reference for the design and application of labyrinth seal in oil pump.
