摘　　要：为了避免抽油杆断杆事故,减轻抽油杆柱的振动,研制了抽油杆减振器。该减振器包括储能器、机壳和密封装置3部分,其中储能器是其核心部件,它能吸收来自抽油杆柱的振荡波峰能量,使抽油杆受力及抽油机运行平稳,电机电流波动较小,具有节能、减振、保护电机和抽油泵等功能。现场应用表明,该减振器性能优良,使用方便,从根本上改善了抽油杆柱的受力,保护了抽油杆柱和抽油泵,减少了作业频次。In order to avoid rod fracture and alleviate rod string vibration, a rod string absorber was developed. It was made up of an accumulator, a shell and a sealing unit. The accumulator was the core, it could absorb the vibrating energy from the rod string, and made the stress of the rod string stable, the motion of the motor steady, and the current fluctuation of the motor smaller. The absorber had following performance： saving energy, shock-absorbing, protection of the rod string and the motor. The application in oilfield proves that the absorber is well in performance, convenient in use, and it improves the stress of the rod string radically, protects the rod string and the pump from breakdown, and reduces the frequency of workover service.
