随着油田进入开采晚期,开采难度不断增大,机械采油系统存在效率下降、能耗升高的情况。分析认为影响机采系统工作效率的因素主要有:电动机工作特性、泵效、设备摩擦阻力、采油生产管理工作等。为了改善机采系统能耗现状,使用永磁同步电机、变频调速控制装置等节能设备提升系统运行效率,对机采系统进行防偏磨治理消除设备运行的摩擦阻力,加强采油生产日常管理工作等,相关节能技术的应用取得了较好的应用效果。 As the oilfield enters the late stage of mining, the difficulty of mining increases continuously, and the mechanical recovery system has the problems of decreased efficiency and increased energy consumption. Analysis that the main factors that affect the efficiency of mechanical mining system are: motor operating characteristics, pump efficiency, equipment frictional resistance, oil production and management work. In order to improve the energy consumption status of machine-picking system, energy-efficient equipment such as permanent-magnet synchronous motor and inverter speed control device are used to improve the system operating efficiency. Anti-skid control of machine picking system is adopted to eliminate the frictional resistance of equipment operation and to strengthen daily management of oil production Etc., the application of related energy-saving technologies has achieved good results.
