五点法确定潜油电泵特征参数

Determining Performance Parameters for Electrical Submersible Pumps(ESP)

潜油电泵采油在油田的应用日趋成熟,型号也逐渐增多,但其详细参数很难获取。提出了用特征参数表征潜油电泵特性曲线的方法,并从水力学角度推导出了用潜油电泵特性曲线上的5点参数求取表征潜油电泵特征参数的系列公式,同时用实际的泵参数验证了该方法的正确性和合理性。

ESP is widely used in oilfields, the pump types increase gradually, but its detail parameters are difficult to be obtained. Methods are proposed for characterizing its performance curves with its performance parameters, a series of formulae for characterizing, its performance parameters are derived by using 5-point parameters on its characteristic curves from the aspect of hydraulic feature, the correctness and rationality are proven by actural pump parameters.
