Pump dynamometer card shape directly reflects the characteristics of different factors that influence the working performance of sucker rod pump performance
泵功圖的形狀直接反映著抽油泵受不同因素影響下的特征。
Using the finite difference method , the wave equation describing the dynamic change of sucker rod is solved , the pump dynamometer card is calculated combining with practical example , the pump dynamometer card taken from that calculating method is analyzed , and the governing factors influencing working performance of sucker rod pump are pointed out , the performance and efficiency of sucker rod pump are improved by the reasonable adjustment of suction parameters
本文利用有限差分法求解了描述抽油桿柱動態(tài)變化的帶阻尼的波動方程，計(jì)算出了反映抽油泵工作性能的泵功圖。結(jié)合實(shí)例，對仿真得出的泵功圖進(jìn)行分析，找出了影響泵況的主要因素，通過參數(shù)調(diào)整，改善了抽油泵性能，提高了油井效率。
