摘　　要：现有抽稠泵抽吸稠油时,往往出现柱塞下行阻力较大,液压反馈力小,致使杆柱下行屈曲变形,泵效低,严重时杆管之间的偏磨倒井问题突出。研制的YLFK型长柱塞抽稠泵下行时增加了作用在抽油杆柱上的较大向下液压反馈力,泵效大幅度提高,减缓了杆柱屈曲变形的问题,有效、低成本解决了杆管之间偏磨的问题。Because of existing heavy oil pump swabbed heavy oil, usually the resistance of plunger downwards was great, and hydraulic feedback was small, resulting in flexural deformation of sucker rod and pump efficiency low, seriously, eccentric wear of rod and pipe in operation of oil well. Aiming at the problem, YLFK long plunger swabbing heavy oil pump was developed. The pump added great hydraulic feedback force to sucker rod when the pump was down and effectively overcome the shortcoming and deficiency of current technology, pump efficiency was advanced greatly. At the same time, the pump relieved the problems of flexural deformation of sucker rod and effectively resolved the problems of eccentric wear of rod and pipe.
