摘　　要：为落实能源消费强度和总量双控的制度,实现碳达峰、碳中和目标,某油田在机采节能新技术上,始终坚持“应用一代、研发一代、储备一代”的思路,不断推广应用效果显著、经济效益好的节能技术和产品。一是当选择具体的节能拖动装置时,建议选用永磁半直驱拖动装置;对于供液不足的低产井,建议选用不停机间抽装置。二是高转差电动机适合工况多变的油井或抽油机要求冲次范围大、单速电动机无法满足要求的井;永磁同步电动机适合作为老化、低效、高耗能的常规电动机的替代电动机;高扭矩节能电动机适合应用在负载大、电动机功率利用率低的抽油机井。该油田通过应用以上机采节能新技术,有效地完成了机采系统的节电量计划,对以后的节能技术改造投资具有指导意义。To implement the system of double control of energy consumption intensity and total amount and achieve the goal of carbon peak and carbon neutralization,an oilfield has always adhered to the idea of "application generation,R & D generation and reserve generation" in the new energy-saving technology of mechanical production and continuously promoted the energy-saving technologies and products with remarkable application effect and good economic benefits:1、When selecting specific energy-saving driving device,it is recommended to select permanent magnet semi-direct driving device.In view of low production wells with insufficient liquid supply,it is recommended to select the pumping device in the non-stop room.2、High slip motor is suitable for oil wells or pumping units with variable working conditions,which requires a large range of strokes.In particular,the single speed motor can’t meet the requirements.The aging,inefficient and high consuming conventional motor have been displaced by permanent magnet synchronous motor(PMSM).High torque energy-saving motor is suitable for pumping wells with large load and low motor power utilization.By using the above new energy-saving technologies,the oilfield has effectively completed the power-saving plan of the mechanical production system,which has a significant impact on the investment in energy-saving technology in future.
