完整的论文介绍了用于电潜泵 (ESP) 系统的新型机械气体分离器的研究、设计和现场测试，该分离器可增加操作流量范围和分离效率，同时减少腐蚀问题并提高可靠性。水螺旋分离器系统已在不同类型的井中被证明是有效的。
存在多种避免 ESP 中产生气体的方法和技术，包括倒置护罩、被动分离器、机械气体分离器和串联气体分离器。大多数都存在流量能力有限和总流量较高时性能降低的局限性。
与复杂的两相流行为、内部和外部压力变化、分离方法、流体的速度和粘度、上面螺栓连接的泵的影响、固有的腐蚀问题以及单与串联设计相关的许多变量增加了基本设计的挑战机械气体分离器操作。
2016年，启动了一项计划，重点投资经验丰富的人员和先进的测试技术，以解决上述挑战并提高对井下机械气体分离操作的了解。
The complete paper presents research, design, and field testing of a new type of mechanical gas separator for electrical submersible pump (ESP) systems that increases operating flow range and separation efficiency while decreasing erosion problems and improving reliability. The hydrohelical separator system has been proved effective in different types of wells.
Several methods and techniques exist for avoiding gas in ESPs, including inverted shrouds, passive separators, mechanical gas separators, and tandem gas separators. Most share the limitations of limited flow capabilities and reduced performance at higher total flow rates.
The many variables associated with complex two-phase flow behavior, internal and external pressure variations, separation methods, velocity and viscosity of fluids, effect of the pump bolted above, inherent erosion issues, and single vs. tandem designs add to the challenge of basic mechanical gas-separator operation.
In 2016, a program was initiated that featured investment in both experienced personnel and advanced testing technology to unravel the aforementioned challenges and improve understanding of the operation of downhole mechanical gas separation.
