| 摘 要： | 针对原抽油泵在高含水、高含砂、高矿化度介质中工作,寿命降低的问题,对其结构和材质进行了改进,活塞在原结构基础上增加了高硬度刮砂环。改进后的抽油泵现场可对比的14口井的泵效同比高于上次的泵效。其中3352井下高硬高环抽油泵稳定生产150 d,泵效仍达71％,与上次施工同比高10个百分点,证明高硬度环抽油泵的抗砂耐磨能力有所提高。

| Abstract: | The service life of the subsurface pumping unit will be lowered when operating in the medium of high water-cut and sand content and high degree of mineralization. Thereby the structure and material of the pump are improved. A sand-scraping ring with high hardness is added on the plunger of the pump. Field use shows that the efficiency of the modified subsurface pump is improved obviously. |
