基于GIBBS方程的油井泵功图计算与相似性分析

Pump Diagram is the closest indicator diagram of the actual working condition in the oil fields' pumping system. This paper established mathematical model of oil well based on Finite Element Analysis Method, used one-dimensional GIBBS equation to compute the pump diagram of oil well, Built a parameters' set to analyze the measured pump diagram similar, analyzed in the solving process of pump diagram effects of various factors, calculated similarity between computed pump diagram and measured diagram. The computation and similarity analysis method has been applied in JiangSu Oilfield.
