Abstract: In order to effectively develop deep reservoirs, the selection of pumps in deep pumping technology is a difficult problem for Tahe oilfield. The optimization of deep pump should avoid the problems of large oil bar load, low pump efficiency, short pump detection period and high difficulty of deep well pumping, etc. By investigating the field application of the pump, the characteristics and parameters of the oil recovery work of five common deep pumpes were analyzed and compared. As a result, the deep pumping with side⁃flow loading pumps has the advantage of reducing the load on the sucker rod string. The actual pump depth of deep pumping with bi⁃lamellar pump is the largest. Deep pumping with self⁃compensating pump can reduce pump leakage, prevent sand sticking and prolong the life of deep pump.The oil pump of hydraulic feedback can solve effectively the problem of downward of rod string.The electric submersible pump and rod pump combination can significantly improve pump efficiency. The article provides some reference to the selection of mechanical production mode for other deep wells or the wells with insufficient fluid supply at the bottom of the wells.

摘要： 深抽工艺中泵的选取是塔河油田高效开采深层油藏面临的难题。深抽泵的优选应尽可能避免深井举升载荷大、泵效低、检泵周期短、难度大等问题。通过调研泵的现场应用情况，对五种常用深抽泵的采油工作特点及参数进行了分析对比。结果表明，实际生产中，侧流减载泵可以有效降低抽油杆柱载荷；双层泵的下泵深度最大；自动补偿泵可降低漏失和预防砂卡，延长深抽泵寿命；液压反馈式深抽泵能减小抽油杆柱的下行阻力；电潜泵⁃有杆泵复合深抽工艺可以明显提高泵效。研究结果对其他油田深井或井底供液能量不足井的机采方式的选择具有一定参考意义。
