游梁式抽油机是油田广泛使用的一种抽油机,它结构简单、运行可靠,赢得用户的欢迎。其型号从早期的3型发展到目前的14型,应有尽有,满足了不同井况的生产需求。 但是,游梁式抽油机在使用中出现了一些不该发生的事故,游梁从井架上翻下 Beam pumping unit is widely used in the oil field pumping unit, it is simple in structure, reliable operation, won the user’s welcome. Its model from the early 3-type development to the current 14-type, everything possible to meet the production needs of different well conditions. However, the beam pumping unit in use there have been some accidents that should not happen, beam down from the derrick
