摘要
正确认识抽油机井的生产过程是准确计算抽油机井系统效率的前提。现行的抽油机井系统效率计算公式的不足在于忽视了井中流体是多相流这一客观事实,本文在对抽油机井系统效率进行全面分析研究的基础上导出了新的计算公式。
Correctly understanding the production process of pumping unit wells is the prerequisite for accurately cal-culating the system efficiency of pumping unit wells.The fault of the current formula in use ignores the ob-jective fact that the fluid in wells is multiphase flow.Based on this the article deduces a new formula.
