异形游梁式抽油机是对常规机结构进行了改进，适用于中、低粘度原油和高含水原油开采，是一种较理想的地面采油设备。异形游梁式抽油机与常规游梁式抽油机相比，是将游梁后臂制成一个半径按一定规律变化的变径圆弧形状，将游梁后臂与横梁之间采用柔性件连接。经过5年来的现场应用结果表明，这种抽油机不仅保留了常规游梁抽油机坚固耐用、工作可靠、维护方便的特点，还具有运转平稳、附加载荷小、冲程长、平衡效果好、能耗低、综合效率高等优点，适合大面积推广。
Profiled beam pumping unit is the conventional machine structure has been improved for medium and low viscosity crude oil and crude oil mining is an ideal ground oil production equipment. Compared with the conventional beam pumping unit, the beam-shaped pumping unit has the shape of an adjustable arc with a radius varying according to a certain rule, and uses the flexibility between the rear beam of the beam and the beam Connection. After 5 years of field application results show that this pumping unit not only retains the conventional beam pumping unit rugged, reliable, easy to maintain features, but also has a smooth operation, additional load, long stroke, the balance effect is good, Low energy consumption, high overall efficiency, suitable for large-scale promotion.
