摘　　要：抽油机井机械举升是目前常规采油的主要方法,常规抽油机举升能耗高、系统效率低是节能技术改造的重点。针对电动机和传动系统效率低及供排关系调整问题进行分析,应用双速双功率电动机提高电动机效率,采用永磁半直驱拖动装置提高传动效率,运用多功能调速配电箱优化供排关系。评价节能改造技术的应用效果和经济效益,共改造1268口井,年节电约1828.6×10^(4)kWh,直接经济效益1191.6万元,系统效率提高2.71%。现场应用为节能降耗、控本增效提供有效技术指导。Though mechanical lifting of pumping wells is the main method of conventional oil production,the energy consumption and efficiency of mechanical oil production have always been the prominent contradiction in the process of energy-saving technical transformation.In this paper,the low eficiency of motor and transmission system and the adjustment of supply and discharge relationship are analyzed.The double speed and double power motor is used to improve the motor efficiency and the permanent magnet semi-direct drive driving device is used to improve the transmission efficiency.The multi-functional speed regulation distribution box is used to optimize the supply and discharge relationship.The application effect and economic benefit of energy-saving transformation technology are evaluated,which saves about 1828.6×10^(4)kWh in the annual power,directly gets 11.916 million yuan in economic benefit and increases by 2.71%in the system efficiency.Field application provides effective technical guidance in saving energy,reducing resource consumption,controlling cost and raising efficiency.
