摘要/Abstract

摘要： 随着调流势技术在塔河油田的推广应用,大排量稠油电泵暴露出引接电缆烧毁、保护器失效故障率高的问题。为解决该问题,借助三维温度场有限元仿真分析方法,基于永磁电机拓扑结构和电机头部散热结构优化等措施,减少热量聚集,提升引接电缆耐温性能;通过物理隔离设计及迷宫型流道设计等方法,利用重油隔离液密度高、稳定性强的特点,设计带有动态“液体活塞”的重油保护器,实现稠油与胶囊腔的物理隔离,避免稠油直接接触引发保护器胶囊失效。通过电机及保护器的优化设计,提升大排量稠油电泵对调流势技术的适应性,为该技术在塔河油田的推广应用提供技术支撑。

Abstract: With the promotion and application of flow potential regulation technology in the Tahe Oilfield,high-flow-rate heavy-oil electric submersible pumps have exhibited high failure rates such as motor lead cable burnout and protector failure.To address these issues,a three-dimensional temperature-field finite element simulation method was applied.By optimizing the topology of permanent magnet motors and the heat-dissipation structure of motor heads,heat accumulation was reduced and temperature resistance of motor lead cables was improved.Through physical isolation design and labyrinth flow-path design,and leveraging the high density and strong stability of heavy-oil isolation fluids,a heavy-oil protector with a dynamic“liquid piston”was designed to achieve physical isolation between heavy oil and the capsule chamber,thus avoiding protector capsule failure caused by direct contact with heavy oil.Through optimization of the motor and protector designs,the adaptability of high-flow-rate heavy-oil electric submersible pumps to flow potential regulation technology was improved,providing technical support for promoting this technology in the Tahe Oilfield.

Key words: electric submersible pump, permanent magnet motor, flow potential regulation technology, heavy oil, Tahe Oilfield
