摘要: 影响深井泵泵效的原因是多方面的,它与泵的结构、加工精度、油井状况以及地面设备有关。本文立足于无游梁抽油机长冲程低冲次的运动特性,阐述其时泵效的影响,通过时比分析,说明无游梁抽油机由于其良好的运动特性,使得泵效远高于游梁抽油机的泵效。

关键词: 无游梁抽油机 长冲程抽油机 泵效

Abstract: There are many factors which affect the pump efficiency.Based on the
features such as long stroke and low speed of a no一beam pumping unit,this paper analyzes its pump efficiency.It is concluded that the pump efficiency of a no一beam pumping unit is higher than that of a beam pumping unit.

Key words: No-beam pumping unit Long stroke pumping unit
