摘　　要：鉴于电动柱塞泵增压注水时，需要新建泵房，维修工作量大，研制了潜油倒置式增压注水电泵，这种注水泵与常规电泵机组不同的是离心泵是倒置的，应用时配以专用的过电缆高压井口悬挂器，实现井口高压密封。这种泵具有户外安装无需建泵房、无噪声、无介质漏失、不污染环境、运转寿命长和免维护等特点。在胜利、辽河油田等６口井的应用表明，这种泵具有显著的增压注水效果，适合于边远井的增压注水。In boosting water injection by using the electric plunger pump, new pump room should be built and more work for maintenance should be done. Thereby a new submersible electric pump is developed. The difference of the new pump from the conventional pump is that the centrifugal pump is placed upside down, and it is provided with through-cable wellhead hanger to realize high-pressure seal. The new pump is characterized by noiseless, no loss of medium, no pollution, long service life and needing no maintenance. Field use shows that the pump has good performance, and is suitable for boosting water injection of marginal wells.
