针对中原油田日趋老化 ,井况复杂 ,采油成本增高 ,以及在用常规游梁式抽油机能耗大 ,机型陈旧 ,不能适应油井深抽工艺需要的现状 ,对常规游梁式抽油机进行了增程降耗技术改造 ,即根据“六连杆传动技术”增加了弯梁和推杆两构件。改造机有增程型和增程 -节能型 ,两者的结构相同 ,不同的只是在设计时改变各连杆的相对长度。增程 -节能型既能保证冲程有所增加 (约 3 0 %) ,又能使电动机节能保持在 3 0 %～ 4 0 %以内 ;增程型的主要目标是增大冲程 ,冲程最大可增至原机的 1 50 %。 2 6台改造机投入了现场使用 ,收到了增程节能效果。
In view of the aging of Zhongyuan oilfield, complex well conditions, increased oil production costs, as well as the conventional beam pumping unit with large energy consumption, obsolete models can not meet the needs of deep well pumping process, the status of the conventional beam pumping unit Increased energy consumption reduction technology, that is, according to the “six-link transmission technology” added a curved beam and putter two components. Retrofit machines have extended range and extended range - energy-saving, both the same structure, the only difference is that the relative length of the connecting rod in the design change. Extended range - energy-saving can not only ensure an increase of stroke (about 30%), but also to keep the motor energy conservation within 30% ~ 40%; extended range of the main goal is to increase the stroke, the maximum stroke increase To the original machine 150%. 2 6 modified machine into the field, received a range of energy-saving effect.
