试析地面驱动螺杆泵采油技术优化

摘要

The driving head of surface progressive cavity pump(PCP) is driven by the eectromotor,the rod and sucker are put in motion after deceleration to drive the rotor rotating for pumping. This paper focuses on PCP upgrading.%地面驱动螺杆泵是由地面电动机带动驱动头,经减速带动光杆和抽油杆柱旋转,驱动螺杆泵转子旋转抽油的一种抽油泵.本文着重就其优化技术进行了分析与探讨.
