摘要
在对有杆抽油系统行为预测上,S·G·吉布思提出了抽油系统的预测模型,建立了带阻尼的一维波动方程,在进行有杆抽油系统波动方程的计算时,一个重要的工作就是等效阻尼系数的确定。从试验出发,根据试验数据多元函数插值方法给出抽油机井不同含水率、不同工况下的等效阻尼系数的曲线,为油井的实际计算提供了依据。
S.G.Gibbs proposed the prediction model of pumping system,and established the damping of one-dimensional wave equation;the most important work in solving wave equation is the determination of the equivalent damping coefficient.According to multi-function interpolation method,the different water content of pumping wells and equivalent damping coefficient curve in different condition are given,which provides basis for calculation of the actual oil wells.
