永磁电机 (PMM) 技术在哥伦比亚 Llanos Norte (LLN) 和 La Cira Infantas (LCI) 油田的不同人工举升系统中进行了评估和实施，旨在寻找更高效的电机来节省能源消耗并减少碳足迹。完整的论文分享了在现场进行的测试评估的技术细节，以验证 PMM 技术在人工举升系统中的实施、减少二氧化碳 (CO 2 ) 吨数的计算以及其应用中的主要挑战：未来项目的节能解决方案。

领域背景

截至撰写本文时，Llanos Orientales 盆地已安装 482 口电潜泵 (ESP) 和 24 口抽油泵 (SRP) 井，平均深度为 7,450 英尺真实垂直深度 (TVD)。LCI 是另一个正在研究的油田，是哥伦比亚的第一个生产油田，拥有三种不同的人工举升系统来生产油井：215 个螺杆泵 (PCP) 装置、691 个 SRP 装置和 257 个 ESP 装置。景深平均深度为 3,500 英尺 TVD。

PMM技术在运营商能源领域的应用背景

2016年，首次尝试在LLN和LCI领域将PMM技术应用于ESP设备。该项目于同年 11 月开始，在 LLN 进行了试验，在两口 ESP 井中安装了 PMM。

Permanent Magnet Motors Help Reduce Carbon Footprint in Artificial Lift Systems

The authors describe implementation of permanent-magnet-motor technology in different artificial lift systems that has resulted in power savings of more than 15% and lifting-cost optimization.

Permanent-magnet-motor (PMM) technology was evaluated and implemented in the different artificial lift systems in the Llanos Norte (LLN) and La Cira Infantas (LCI) fields in Colombia, aiming to find a more-efficient motor to generate energy consumption savings and reduce carbon footprint. The complete paper shares technical details of the evaluation of tests performed in the field to validate the implementation of PMM technology in the artificial lift systems, the calculation of reduction of tons of carbon dioxide (CO2), and the main challenges in its application as an energy-efficient solution for future projects.

Field Background

The Llanos Orientales basin has 482 installed electrical-submersible-pump (ESP) and 24 sucker‑rod-pump (SRP) wells at the time of writing, at an average depth of 7,450 ft true vertical depth (TVD). LCI, the other field under study, is Colombia’s first producing field and has three different artificial lift systems to produce its wells: 215 progressive-cavity-pump (PCP) installations, 691 SRP installations, and 257 ESP installations. The average depth of the field is 3,500 ft TVD.

Background for PMM Technology in the Operator’s Energy Fields

In 2016, the first attempt to implement PMM technology for ESP equipment in the LLN and LCI fields was made. The project began in November of the same year with a trial test in LLN with the installation of PMMs in two ESP wells.
