Abstract

This letter proposes a fiber-optic-based method for monitoring the temperature of stator windings and housing regions in electric submersible pump (ESP) motors using Raman distributed temperature sensing (RDTS). The experimental setup replicates conditions of downhole installations or subsea skids by enclosing the ESP within an unplasticized polyvinyl chloride pipe, with annular flow established between the motor housing and the inner wall of the pipe. Flow rate and electric parameters are continuously monitored to evaluate their relationship with motor temperature. The results indicate that RDTS can be an intrinsically safe solution for temperature monitoring in ESP-lifted wells for oil and gas production, where conventional electric-based sensors are often unsuitable due to limited installation space, harsh environment, high electromagnetic interference, and long distance between the ESP motor and platform.

基于拉曼分布温度传感的潜水泵电机对负载变化的热响应实验研究

本文提出了一种基于光纤的方法，用于使用拉曼分布式温度传感（RDTS）监测电潜泵（ESP）电机定子绕组和外壳区域的温度。实验装置通过将ESP封闭在未塑化的聚氯乙烯管道中，在马达外壳和管道内壁之间建立环空流动，复制了井下安装或海底滑块的条件。连续监测流量和电气参数，以评估其与电机温度的关系。结果表明，对于ESP举升井的温度监测，RDTS是一种本质安全的解决方案。在ESP举升井中，由于安装空间有限、环境恶劣、电磁干扰大、ESP电机与平台之间距离远，传统的电传感器往往不适合进行温度监测。
