乌石23-5油田群开发项目采用岸电。钻完井项目组为落实有限公司湛江分公司（下称有限湛江）节能降碳工作会指示要求，秉承高效开发和绿色低碳一体化思路，采用永磁电机替代励磁电机，降低油田电潜泵电机采井耗电量。

永磁电机转子用永磁体取代导条，无需励磁，显著降低无功损耗，系统效率较感应电机提高20%以上

具有“能耗小、尺寸小、发热小、运行电流小、震动小、频率调节大、启泵扭矩大”等诸多优点

单井按100kW机组计算，可实现年节电17.5万度，相当于减少燃烧标准煤70吨

钻完井项目组根据永磁电泵技术特点、储层物性、井况条件、生产条件等方面，提前在乌石油田群开发井中选井，实现永磁电泵“应用尽用”，最终确定在首批两口井中应用。

作业前，项目组与永磁电泵机组厂家进行探讨，深入了解永磁电机与励磁电机区别。

作业时，项目组制定详细施工方案，针对永磁电泵带来的馈电风险及时向作业人员宣贯，确保作业安全。

作业后，项目组与生产方及时交流永磁电泵生产管理操作规程，保障永磁电泵及操作人员长期的工作安全。

The development project of Wushi 23-5 oil field group adopts shore power. In order to implement the instructions for energy saving and carbon reduction work of Zhanjiang Branch Co., LTD. (hereinafter referred to as Zhanjiang Co., LTD.), the drilling and completion project team adopts the permanent magnet motor to replace the excitation motor and reduce the power consumption of the oilfield electric submersible pump motor.

The rotor of the permanent magnet motor replaces the guide bar with a permanent magnet, without excitation, significantly reducing reactive power loss, and the system efficiency is more than 20% higher than that of the induction motor

It has many advantages such as "small energy consumption, small size, small heat, small running current, small vibration, large frequency regulation, and large starting pump torque"

According to the calculation of 100kW unit, a single well can achieve an annual power saving of 175,000 degrees, which is equivalent to reducing the burning of 70 tons of standard coal

According to the technical characteristics of permanent magnet electric pump, reservoir physical properties, well conditions, production conditions and other aspects, the drilling and completion project team selected Wells in the development Wells of Wushi oilfield group in advance to realize the "application of permanent magnet electric pump", and finally decided to apply in the first two Wells.

Before the operation, the project team discussed with the manufacturer of permanent magnet pump unit to deeply understand the difference between permanent magnet motor and excitation motor.

During the operation, the project team formulated a detailed construction plan and publicized to the operators in a timely manner the feeding risks brought by the permanent magnet electric pump to ensure the safety of the operation.

After the operation, the project team and the manufacturer communicate the operation procedures of permanent magnet pump production management in time to ensure the long-term work safety of permanent magnet pump and operators.
