| Abstract: | At present, the pump leakage and low efficiency of rod system are serious problems in the procedure of oilfield development. As one kind of low-cost and convenient toni, stimulative nipple is effective in stroke loss reducing, eccentric wear and leakage mitigating, pump efficiency improving. Through theoretical analysis and combined with field application, this paper elaborated the mechanism of stimulative nipple. Through the improvement of stimulative nipple configuration, the optimal number of installation and the maximum of efficiency promotion were drawn. The calculation model for installation number and efficiency promotion of stimulative nipple were built. |
