常规抽油机的增程节能改造

Modification of conventional beam pumping unit for stroke increment and energy saving

介绍了常规抽油机进行增程节能改造的可行性 ,并以CYJ10— 3— 5 3HB型常规抽油机为实例论述了增程节能改造的具体方法、改造前后参数的变化及改造成的异相游梁平衡旋转驴头抽油机的性能。实践表明 ,常规抽油机经增程节能改造后 ,在满足使用条件下 ,不仅可增加产液量 4 0 % ,节电 15 %以上 ,而且还可以充分利用油田现有的抽油设备 ,大大减少固定资产的投资 。

The feasibility of modifying the conventional beam pumping unit for stroke increment and energy saving is analyzed. By taking Model CYJ10-3-53HB conventional pumping unit as an example, the article introduces the method for modifying the pumping unit into the phased beam-balancing pumping unit with rotary horsehead, the variation of operating parameters of the unit before and after modification and the performance of modified unit. Practice proves the modified pumping unit has good energy saving effect since its stroke is enlarged to a certain extent.
