摘要

油气行业继续推动海底泵送技术的发展,以最大限度地减少对支持系统的需求,并提高系统的可靠性。屏蔽电机技术已成功应用于其他应用,以实现类似的目标,包括驱动海底双螺杆泵。在水下应用时,屏蔽式电机无需在电机内安装任何屏障流体,无需存储和补充这些流体所需的无数系统和复杂性,也无需机械轴封来防止电机内流体的泄漏和/或污染。如图1所示,水下水处理是罐装马达技术的理想选择。因此,一项开发工作已经启动,并将于2020年完成,以展示第一个真正的无流体、无密封海底泵解决方案。本文的目的是确定该技术的新元素,审查系统配置,并描述该正在进行的设计和鉴定计划的过程和挑战。

Barrier Fluidless, Sealless Seawater Canned Motor Pumps
The oil and gas industry continues to push toward subsea pumping technologies that minimize required support systems and increase system reliability. Canned motor technology has been applied successfully in other applications to achieve similar objectives including driving a subsea twin-screw pump. Applied subsea, canned motors eliminate the need for any barrier fluids within the motor, the myriad of systems and complexities necessary to store and replenish these fluids, and the mechanical shaft seals required to prevent the leaking and/or contamination of these fluids within the motors. As a direct adaptation of proven applications, seeFigure 1, subsea water treatment is ideal for canned motor technology. Therefore, a development has been initiated and will be completed in 2020 to demonstrate the first truly barrier fluidless, sealless subsea pump solution. This purpose of the paper is to identify the novel elements of this technology, review the system configuration, and describe the process and challenges of this ongoing design and qualification initiative.
