摘　　要：对油田常规游梁抽油机进行节能改造,在保证原机最大抽汲参数不变的情况下,从降低改造成本出发,保持原机曲柄装置、连杆及基杆的结构尺寸不变,优化游梁后臂的长度、初始角及极位夹角,并采用复合平衡方式.现场应用表明,改造后抽油机的运动特性和动力特性得到改善,能耗降低,平均节电率在15%以上.整机运转平稳,工作可靠.The energy saving reconstruction technology for conventional beam pumping unit is studied.On the condition of keeping the original largest working parameters and not increasing the reconstruction cost,the original size of crank,coupler and base rod are kept unchanged,but the length of back beam,initial angle and the crank angle between two limit positions are optimized.The compound balance mode is also adopted.The actual applications show better motion features and dynamical features for reconstructed bumping unit,the energy consumption is decreased and the average energy saving rate is more than 15%.The unit works stably and the reliably.
